| 摘 要： | 利用已知的塑性力学分析结果,采用塑性极限上限分析方法,建立被动土压力三角形破坏机构,推导其基本计算公式,并编制相应程序找出最优破坏机构,得出被动土压力最优上限解。将计算结果与库仑解以及其他极限分析结果进行比较,表明计算结果合理,方法简便,易于编程。

| Abstract: | Based on the analysis result of plastic mechanics that has been already known,triangle failure mechanism of passive earth pressure is established using plastic upper limit analysis method to educe the basic calculation formula.The corresponding program is prepared to find the optimal failure mechanism in order to get the optimal upper limit solution of passive earth pressure.Comparing the calculation result with the traditional Coulomb's solution and other limit analysis results,it is shown that this result... |
