为了促进石碴坝的的发展,以利水利建设,我们综合四川省简阳县石盘水库,用有限单元法对石碴坝的应力应变进行了非线性增量分析。分析时视坝体为平面应变问题,采用了三角形单元,荷载分八次施加。在具体的非线性分析方法上,既采用了“中点增量法”,也探索了“中点增量迭代法”。分析工作的一部分,完全是针对石盘水库石碴坝的;另一部分则研究了石碴坝的某些共 In order to promote the development of the ballast dam and facilitate the construction of the water conservancy project, we integrated the Shiban reservoir in Jianyang County, Sichuan Province and carried out nonlinear incremental analysis of the stress and strain of the ballast dam with finite element method. Analysis of the dam as a plane strain problem, using a triangular unit, the load points applied eight times. In the specific non-linear analysis methods, both the “midpoint incremental method”, but also explored the “midpoint incremental iteration method.” Part of the analysis is directed at the ballast dam of Shiban Reservoir; on the other hand, some of the ballast dam
