If the value of the coefficient of lateral earth pressure at rest (KO) for the compressible silty clay layer of Problem 2 is 0.68, what are the total and effective horizontal stresses at mid-depth of the layer in parts (a) and (b) of Problem 2? ● Problem 2 The soil profile shown in Figure 1 consists of 5 meters of compacted sandy clay underlain by 5 m of medium dense sand. Below the sand is a layer of compressible silty clay that is 20 meters thick.
