3:1 eFdRRkFpWVRRMDFjYzVjZ2Vz... Done 4 of 10 2 Soil Mechanics - Homework Dr Haluk Isik 2 Problem 2 A clay layer of 4 m thickness with
\rho _(sat)=2.0Mgm^(-3)is overlain by a 4 m thick sand layer with
\rho _(sat )=1.9Mgm^(-3)and
\rho _(dry )=1.65Mgm^(-3), the top of this layer being the ground surface. The water table is located 2 m below the ground surface. The clay layer is underlain by a sand stratum that is in artesian conditions, with the water level in a standpipe being 4 m above the ground surface. Calculate: (a) The effective vertical stress at the top of the clay layer (b) The effective vertical stress at the base of the clay layer (c) If the dry sand is excavated, at what depth will the effective stress at the bottom of the clay layer become zero?
