摘要
对水平层单元体模型及土拱效应模型两种非线性土压力理论进行了研究,并结合试验资料进行算例分析,在此基础上提出一种能考虑位移、时间效应的,且能体现土压力非线性分布规律的土压力计算模型。算例分析结果能与实际规律较好地吻合。
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.
