| Abstract: | In this paper, the anisotropy of undrained shear strength induced by initial anisotropic stress state is taken into consideration.Based on the constitutive equation of the anisotropic clays, the theoretical values of the undrained shear strength of normally consolidated and slightly overconsolidated clays can be obtained. Using the theoretical strength results for the analysis of resistant heave stability for deep excavations, the safety factor of stability can be achieved and the analysing method is verified by the practical engineering example. |
