Parameter Analysis on Hardening Soil Model of Soft Soil for Foundation Pits Based on Shear Rates in Shenzhen Bay, China

Table 1

The applicable conditions for different constitutive models of cemented clay and soft soil.

Constitutive models	Analysis type	Soft soil			Cemented clay
		OCR > 1	OCR≈1	OCR < 1	Sandy soil	Low compressibility	High compressibility
MC model	Serviceability limit state
	Bearing capacity limit state	+			++	+
DC model	Serviceability limit state	+			++	++	+
	Bearing capacity limit state	+			++	++	+
DP model	Serviceability limit state	++	+	+	++	++	++
	Bearing capacity limit state	++	+	+	++	++	++
Modified CC model	Serviceability limit state		+	+			+
	Bearing capacity limit state		++	++			++
Cap model	Serviceability limit state	+	++	++	+	+	+
	Bearing capacity limit state	++	++	++	++	++	++
HS model	Serviceability limit state	+++	++	++	+++	+++	+++
	Bearing capacity limit state	+++	++	++	+++	+++	+++

OCR: over consolidation ratio; +: generally applicable, the effect is not ideal; ++: applicable, good effect; +++: applicable, very good effect.
