Abstract:

Based on the basic principle of shear strength reduction, three calculation models of earth pressure for the clay are derived by considering the displacement effect, the calculation results are all agreed well with the centrifugal model test results. No matter from the theoretical perspective or from the calculated values aspects; the second method is the most reasonable among the three calculation models, but it has an applicable scope. The scope is the displacement must be in , that can also be generalized to . Beyond the scope the model one and the model three can all be used.

Key words: cohesive soil, shear strength reduction method, displacement, earth pressure
