A uniform layer of sand 10 m deep overlays bedrock. The water table is located 2 m below the
surface of the sand which is found to have a voids ratio e = 0.7. Assuming that the soil particles have
a specific gravity Gs = 2.7 calculate the effective stress at a depth of 5 m below the surface.
Answer
Unit weight of materials used in Construction The unit weight of materials is an important factor to consider in engineering and construction projects. It refers to the weight of a material per unit volume, typically
Question For the smooth vertical wall shown in Figure Q1, determine the total active thrust on the wall and the position where it acts. Ground water level is at a depth of 1.5 m. Solution
Question A 10 m high retaining wall has been holding a soil with the following composition: G=2.65, e= 0.50, w=10%, and ะค=20 degrees. Determine the active thrust on the wall due to soil and water,
