将极限分析上限法用于加筋土结构物稳定性分析的关键是滑动面上内力功如何计算的问题。在总结了基于传统塑性理论上限法内力功的计算方法的基础上,将基于广义塑性理论的上限法应用到杨俊杰的内力功计算方法中。对比基于传统和广义塑性理论的上限解及离心试验结果,认为基于传统塑性理论的上限法应用简单,计算结果基本可靠;基于广义塑性理论的上限法虽然理论上比较完善,但当滑动面为曲线时,应用繁琐。
The key of using the upper limit analysis method in the stability analysis of reinforced earth structure is how to calculate the internal force on the sliding surface. Based on the calculation method of internal force of upper limit method based on traditional plastic theory, the upper limit method based on generalized plastic theory is applied to the calculation method of internal force of Yang Junjie. Compared with the upper bound solution and the centrifugal test based on the traditional and generalized plastic theory, the upper bound method based on the traditional plastic theory is simple and the calculation results are basically reliable. The upper bound method based on the generalized plastic theory is theoretically perfect, but when the sliding surface is curved When, the application is cumbersome.
