摘要
实验证明,岩土材料不适应关联流动法则,而应采用非关联流动法则。把广义塑性力学理论引入到极限分析的上界法,据此编制了有限元程序,并引入数学规划方法寻求问题的最小上界解。通过和经典解析解的比较可知,该方法是一种合理有效的方法。
The associated flow rule for trandional plastic theory is not in accordance with the geotechnical experiment and the non-associated flow rule should be adopted. The finite element method of upper bound theorem based on the generalized plastic theory and its application are presented. The linear programming method is applied to search the minimum upper bound solution. It is proved that the presented method is reasonable and practicable by comparison with classical solution.
