Experimental determination of HSS model parameters for typical Zhengzhou strata and their application in shield tunnel construction

The hardening small strain (HSS) model can accurately capture the stress-related characteristics of soil during the small strain stage. This model has been widely used in calculating deformations for tunnels and excavations in sand and clay strata. However, research on the appropriate parameter valu...
