2.) THE SOIL PROFILE SHOWS CONSISTS OF A LAYER OF DRY SAND 4m THICK WHICH OVERLIES A LAYER OF CLAY HAVING A THICKNESS OF 6m. GROUND WATER TABLE IS LOCATED AT THE INTERFACE OF THE SAND AND CLAY. a.) COMPUTE THE EFFECTIVE STRESS AT THE BOTTOM OF THE CLAY LAYER b.) IF THE WATER TABLE RISES BY 2m, DETERMINE THE EFFECTIVE STRESS AT THE BOTTOM OF THE CLAY LAYER. c.) IF THE WATER TABLE LOWERS BY 2m, DETERMINE THE EFFECTIVE STRESS AT THE BOTTOM OF THE CLAY LAYER Dry Sand ysat = 18.78 KN/m 2.00 V Ground Water Table 2.00 ysat (sand) = 21.58 KN/m Gs = 2.72 e = 0.90 6.00 Clay
