| Abstract: | Two kinds of nonlinear soil pressure theories on the model of horizontal layer element and soil arch effect are studied in this paper and some examples are analyzed according to experimental data. Based on the research, a new calculation model of soil pressure ,considering the displacement, time effect and embodying the nonlinear distribution rule of, the soil pressure,is put forward too and the example calculation result ：on the new model is closed to the real regular pattern. |
