A Case Study on Stratified Settlement and Rebound Characteristics due to Dewatering in Shanghai Subway Station

Table 1

The properties of the soil samples.

Layer number	Name	Density (g/cm^3)	Water content (%)	Porosity ratio	Cohesive force (kPa)	Internal friction angle (°)
Topsoil*	Silty clay	18.4	39.8	1.13	19	27.5
Layer number 4	Sandy clay	18.1	36.9	1.1	7	31
Layer number 5	Silty clay	18.4	39.8	1.13	20	27

*Means that layer topsoil is the layer with same gravity of all layers above layer number 4 and number 5.
