Calculation of Tangent Modulus of Soils under Different Stress Paths

Table 1

Initial tangent modulus of silty clay under consolidation unloading condition.

Silty clay	Confining pressure   (kPa)	Initial tangent modulus   (kPa)
Lateral unloading	50	2.08 × 10^4
	100	2.94 × 10^4
	200	3.33 × 10^4
Axial unloading	50	3.33 × 10^4
	100	1.00 × 10^5
	200	1.18 × 10^5
