As per Terzaghi theory, NC, N, and N, are known as :

For obtaining allowable load from single pile load test (dop : IS 2911-P1-1964) data, which of the following criteria is applicable :

The degree of disturbance of sample which is measured in terms of Area ratio 'Ar' is defined as :

Match List - I with List - II, and select correct answer using codes given below :

A group of 4 piles with two piles in a row were driven into a soft clay extending from ground level to a great depth. The piles were placed 90 cm c/c with a pile diameter 30 cm and length 8 m. The UCS (Unconfined Compressive Strength) of soft clay is 60 kPa. Compute allowable load on pile group (Assuming block failure ) for a factor of safety 2-5?

The maximum shear stress under the centre of a continuous strip occurs at what depth beneath the centre ? (If ‘B’ is width of the strip)

The standard penetration test is useful to measure :

The shape of the hydrograph of runoff is affected by : 

The uplift pressure on the face of a drainage gallery in a dam is equal to : 

The method of estimating high flood discharge is :

The flow-mass curve is a graphical representation of

What does the Gumbel's distribution method require of the annual flood series to estimate the magnitude of a flood with a return period of T years ?

The percentage of the total sediment flow depositing in the reservoir is called its :

The relation between duty D in hectares/cu.m. depth of water A in mt. and base period in days is given by :

Trap efficiency of a storage reservoir is defined as ratio of:

Match the List - I with List - II
