• ## Question: What is 'floating foundation' ?

Posted in: Civil | Date: 05/09/2015

For a floating raft foundation, or floating foundation, the foundation has a volume such that, were that volume filled with soil, it would be equal in weight to the total weight of the structure. When the soil is so soft that not even friction piles will support the building load, the final option is the use of a floating foundation, making the building like a boat that obeys Archimedes’ principle; it is buoyed up by the weight of the earth displaced in creating the foundation.

• ## Question: What are the major criteria to be satisfied in the design of a foundation?

Posted in: Civil | Date: 05/09/2015

The foundation of a structure is in direct contact with the ground and transmits the load of the structure to the ground. Foundations may be characterised as shallow ( strip or raft) or deep(piles, piers or caissons). When designing foundations, two principal criteria must be satisfied:

Bearing capacity There must be an adequate factor of safety against collapse (plastic yielding in the soil and catastrophic settlement or rotation of the structure).

Settlement Settlements at working loads must not cause damage, nor adversely affect the serviceability of the structure.

There are other considerations that may be relevant to specific soils, foundation types and surface conditions.

• ## Question: What is under-damped system?

Posted in: Civil | Date: 05/09/2015

Damping is an influence within or upon an oscillatory system that has the effect of reducing, restricting or preventing its oscillations. In physical systems, damping is produced by processes that dissipate the energy stored in the oscillation.

• ## Question: What are the differences between ultimate bearing capacity, safe bearing capacit...

Posted in: Civil | Date: 05/09/2015

The various terms which are used in connection with the bearing capacity of soils are summarised under,

1. Ultimate Bearing Capacity of Soils:

The intensity of loading, at the base of foundation, at which soil support fails in shear is called ultimate bearing capacity of soils.

2. Safe Bearing Capacity of Soils:

The maximum intensity of loading that the soil will safely carry without risk of shear failure is called safe bearing capacity of soil. This is obtained by dividing the ultimate bearing capacity by a certain factor of safety, and it is the value which is used in the design of foundation. The factor of safety normally varies from 2 to 3.

3. Net Pressure Intensity:

Let = width of the footing, W1 = weight of soil that was existing above the base of foundation prior to excavation. = total load on the base of the foundation {This being sum of (i) total dead load upto footing top (ii) Self weight of footing (iii) Weight of backfill soil located above the footing (iv) Live load on the foundation due to floors above, and due to snow, wind, seismic forces etc. (wherever applicable)} qn = net pressure intensity

Net Pressure intensity= (Net load on base of foundation/Area of footing)

Net load on base of foundation = (W— W1)

qn = (W-W1)/Bx1

Hence net pressure intensity refers to loading acting on the bottom of the foundation trench, in excess of the weight of soil removed from the trench. Net pressure intensity is normally considered in the design of foundation, thereby utilising the advantages of reduction of loading brought about on account of removal of soil from the foundation trench.

4. Allowable Bearing Pressure:

It is the maximum allowable net loading intensity which can be applied to the soil taking into account the ultimate bearing capacity, the amount and kind of settlement expected and the ability of the given structure to withstand the settlement. It is, therefore, dependent upon both the sub-soil and the type of building proposed to be erected thereon. The allowable bearing pressure adopted in the design of foundation is lesser of the following two values, (a) The safe bearing capacity of soil, or (b) The maximum allowable bearing pressure that the soil can take without exceeding the specified limits of permissible settlement.

• ## Question: Differentiate between magnitude & intensity of an earthquake.

Posted in: Civil | Date: 05/09/2015

Intensity: The severity of earthquake shaking is assessed using a descriptive scale – the Modified Mercalli Intensity Scale. Magnitude:Earthquake size is a quantitative measure of the size of the earthquake at its source. The Richter Magnitude Scale measures the amount of seismic energy released by anearthquake.

• ## Question: What is the importance of drainage in irrigated lands?

Posted in: Civil | Date: 05/09/2015

Irrigation and drainage, artificial application of water to land and artificial removal of excess water from land, respectively. Some land requires irrigation ordrainage before it is possible to use it for any agricultural production; other land profits from either practice to increase production. Some land, of course, does not need either. Although either practice may be, and both often are, used for nonagricultural purposes to improve the environment, this article is limited to their application to agriculture.

• ## Question: What is confined aquifer and unconfined aquifer ?

Posted in: Civil | Date: 05/09/2015

Unconfined aquifers are those into which water seeps from the ground surface directly above the aquifer. Confined aquifers are those in which an impermeable dirt/rock layer exists that prevents water from seeping into the aquifer from the ground surface located directly above.

• ## Question: What is meant by development of a tubewell?

Posted in: Civil | Date: 05/09/2015

A tube well is a type of water well in which a long 100–200 millimetres  wide stainless steel tube or pipe is bored into an underground aquifer. The lower end is fitted with a strainer, and a pump at the top lifts water for irrigation. The required depth of the well depends on the depth of the water table.

• ## Question: Give any two assumptions of wedge theory.

Posted in: Civil | Date: 05/09/2015

Two assumtions are-

1. The backfill soil is considered to be homogenious,isotropic,elastic,dry and cohesionless.

2. The rupture plane is taken to be plane passing through the heel of wall.

• ## Question: What are railway sleepers ?

Posted in: Civil | Date: 05/09/2015

A railroad tie/railway tie/crosstie  or railway sleeper  is a rectangular support for the rails in railroad tracks. Generally laid perpendicular to the rails, ties transfer loads to the track ballast and subgrade, hold the rails upright and keep them spaced to the correct gauge.

• ## Question: Explain the necessity of grade compensation at curves.

Posted in: Civil | Date: 05/09/2015

Grade compensation in curvature is provided to off-load the extra resistance due to to curvature. Compensation in BG is 0.04% per degree of curvature. So while providing/fixing the gradient in a curvature care is to be taken for compensation. It should be in such a way that calculated grade in curvature without compensation should not be steeper than ruiling gradient.  Get the ruiling gradient of the section. As per degree of curvature, calculate the amount of compensation. Flatten the ruiling gradient with compensation.Say the gradient after compensation is (C). Check out proposed gradient in curvature should be equal or flatter than (C).

• ## Question: What is meant by a crossing?

Posted in: Civil | Date: 05/09/2015

A place at which roads, lines, or tracks intersect; an intersection.

• ## Question: What are the essential requirements of a good crossing?

Posted in: Civil | Date: 05/09/2015

A level crossing (a primarily British term; usually known as a railroad crossing in North America) is an intersection where a railway line crosses a road or path at the same level, as opposed to the railway line crossing over or under using a bridge or tunnel. The term also applies when a light rail line with separate right-of-way or reserved track crosses a road in the same fashion. Other names include railway crossing, grade crossing, road through railroad, railroad crossing, and train crossing.

• ## Question: What are the functions of a Railway station ?

Posted in: Civil | Date: 05/09/2015

The redevelopment of railway stations calls for the integration of many different objectives. Two crucial challenges thereby are the development of a common system understanding among the multiple stakeholders with potentially conflicting interests and the structured definition of comprehensive assessment criteria. Defining the functions of the system railway station, i.e. discussing what the system should do, can support solving these challenges. Based on a review of Swiss railway stations in a transdisciplinary research project applying four focus groups (n=38), 28 expert interviews and two expert workshops, we present a structured framework of five generic functions of railway stations and their interdependencies. The five generic functions are: linking catchment area and transport network, supporting transfer between modes of transport, facilitating commercial use of real estate, providing public space, and contributing to the identity of the surrounding area. Potential conflicts between functions are identified. They concern the competition of multiple functions for space, for customer attention or for revenues as well as increasing system complexities with station size. We illustrate how the framework of functions can be used to foster a common system understanding and to develop assessment criteria. Although elaborated from a Swiss perspective the framework is perceived adaptable to railway stations of other countries.

• ## Question: What is Pusher Gradient?

Posted in: Civil | Date: 05/09/2015

If the ruling gradient is so severe on a section that it needs the help of extra engine to pull the same load than this gradient is known as pusher of helper gradient. In Darjeeling Railways 1 in 37 pusher gradient is used on Western Ghat BG Track.
