Foundation-engineering Questions Set 5:
The value for bearing capacity factor for cohesion, Nc for piles as per Meyerhoff, is taken as
Solution:
The internal angle of friction for general shear failure in soil mechanics is?
Solution:
Which of the following tests is used to calculate the shear strength in shallow foundation work?
Solution:
If an infinite slope of clay at a depth of 5 m has a cohesion of 1 t/m2 and a unit weight of 2 t/m3, then the stability number will be:
Solution:
The methods of Pauw and Balakrishna Rao are based on the assumption of ________.
Solution:
The contact pressure for a flexible footing on any type of soil is:
Solution:
A concrete pile with 20 m embedded length having 50 cm diameter is driven into a homogeneous consolidated clay deposit with c = 30 kN/m2 and α = 0.65. If the safe load carried by the pile is 250 kN, then the factor of safety is
Solution:
The width of a square footing and the diameter of a circular footing are equal. If both the footings are placed on the surface of sandy soil, the ratio of the ultimate bearing capacity of circular footing to that of square footing will be
Solution:
A pile of diameter 0.4 m is fully embedded in a clay stratum having 5 layers, each 5 m thick as shown in the figure below. Assume a constant unit weight of soil as 18 kN/m3 for all the layers. Using λ- method (λ = 0.15 for 25 m embedment length) and neglecting the end bearing component, the ultimate pile capacity (in kN) is_______.
Solution:
Increasing the depth of foundation in saturated clays results in an increased ultimate bearing capacity for strip footings
