The soil profile at a site for a proposed office building consists of a layer of fine sand 10.4 m thickabove a layer of soft, normally consolidated clay 2 m thick. Below the soft clay is a deposit of coarsesand. The groundwater table was observed at 3 m below ground level. Above the groundwater table,saturation is 50%. The void ratio of the fine sand is 0.76 and the water content of the clay is 43%.The building will impose a vertical stress increase of 140 kPa at the middle of the clay layer. Assume the same soil stratigraphy as above. But now the clay is overconsolidated with anOCR =2.5, w = 43%, Cr = 0.05. Determine the primary consolidation settlement of clay, Gs = 2.7 and Cc =0.3
