Aslope is excavated to a depth ofm in a deep layer of saturated clay of unit weightkN.m3; the relevant shear strength parameters are cu =kN/m2 and φu =The rock ledge is at a great depth. The Taylor's stability coefficient for φu = 0 andslope angle is 0.The factor of safety of the slope is :
In an iceberg,of the volume projects above the sea surface. If the specific weight of sea water is 10.5 kN/m3 , the specific weight of iceberg ir kN/m3 is
The modulus of subgrade reaction is obtained from the plate bearing test in the form of load-deformation curve. The pressure corresponding to the following settlement value should be used for computing modulus of subgrade reaction
Lysimeter and Tensiometer are used to measure respectively, one of the following groups of quantities :
A reinforced concrete column contains longitudinal steel equal to 1 percent of net cross-sectional area of the column. Assume modular ratio asThe loads carried (using the elastic theory) by the longitudinal steel and the net area of concrete, are Ps and Pc respectively. The ratio Ps/Pc expressed as percent is
X-component of velocity in a 2-D incompressible flow is given by u = y2 + 4 xy. If Y-com-ponent of velocity 'v' equals zero at y =the expression for 'v' is given by
Some of the structural strength of a clayey material that is lost by remoulding is slowly recovered with time. This property of soils to undergo an isothermal gel-to-soil-to-gel transformation upon agitation and subsequent rest is termed :
