Doubt Point
1. A 10m thick bed of sand is underlain by a layer of clay 6m thick. The water table that was originally at ground level is lowered by drainage to a depth of 4m, whereupon the degree of saturation above lowered water reduces to 20%.
Determine the increase in effective pressure at mid of clay layer due to water table lowering. Given saturated densities of sand and clay as 2.1g/cc and 1.8g/cc and the dry density of sand 1.7g/cc.
