Effect of Vertical Pressure on Horizontal and Vertical Permeability of Soil and Effect of Surcharge Pressure on 3D Consolidation of Soil

Table 2

Coefficient of volume change under different vertical pressures for silty sand with clay soil and silty-clay soil tested by 1D oedometer.

Types of soil	Vertical stress	Coefficient of volume change
	σ (kN/m^2)	mv × 10^−4 (m^2/kN)
Silty sand with clay soil	100	02.90
	200	01.50
	400	00.75
	800	00.56
Silty-clay soil	100	03.80
	200	02.40
	400	01.10
	800	00.86
