Solved Problem on Soil Mechanics

A multistory building with a basement is to be constructed. The top 4 m consists of loose silt, below which dense sand layer is present up to a great depth. Ground water table is at the surface. The foundation consists of the basement slab of 6 m width which will rest on the top ...

A propped cantilever made of a prismatic steel beam is subjected to a concentrated load P at mid span as shown. Q1. If load P= 80 kN,find the reaction R(in kN) (correct to 1-decimal place)using elastic analysis.

Two different soil types (Soil 1 and Soil 2) are used as backfill behind a retaining wall as shown in the figure, where γt is total unit weight, and c' and φ' are effective cohesion and effective angle of shearing resistance

The soil profile below a lake with water level at elevation = 0 m and lake bottom at elevation = -10 m is shown in the figure, where k is the permeability coefficient. A piezometer (stand pipe) installed in the sand layer shows a reading of +10 m elevation.

Beam PQRS has internal hinges in spans PQ and RS as shown. The beammay be subjected to a moving distributed vertical load of maximum intensity 4 kN/m of any length anywhere on the beam. The maximum absolute value of the shear force...
