摘要
本文对清江隔河岩重力拱坝与复杂岩基相互作用进行了三维有限元分析,并着重研究了坝体的应力和变位,地基中结构面的应力和位移规律以及F_(to)断层不抗拉特性对坝体应力的影响。分析成果对该重力拱坝的优化设计和指导施工有所裨益。此外,这也是我们首次利用个人微机进行岩土工程大型复杂的三维课题有限元非线性分析的一个成功实例。
Three-dimensional finite element analysis has been carried out for the interactions between the gravity arch-dam and the complicated foundation of Geheyan in Qingjiang River. Special attentions have been paid on the stress and displacement of the dam body, the regularity of stress and displacement of structural surface in the foundation and the influence on the dam body stress by the no-tension characteristic of fault F10. The results of the analysis are helpful for the optimal design and construction of the dam. Moreover, it is also the first successful case for us to employ the PCAT microcomputer with a DS1-780 coprocessor board to make nonlinear analysis of three-dimensional finite element for the large scale and complicated subject in rock and soil engineering.
