摘要
应用弹粘塑性自适应有限元分析方法，对三峡工程船闸第二闸室边坡开挖的全过程进行模拟分析，得出了有关应力，变形和屈服的一些认识。成果表明：与常规的有限元分析相比，自适应可使前处理简化，便于优化设计；软件具有某种标准性和规范性，易于工程技术人员掌握。
Elasto-viscoplastic adaptive finite element method is implemented in the simulation of the excavation process of the navigation lock in Three Gorges Project, by which the stress distribution, the deformation pattern, as well as the safety factor of plastic yield in the rock masses during and after excavation are obtained. The results show that, compared to the conventional FEd, the adaptivity leads to the following improvements: (1) the pre-processing. is simpler, (2) the corresponding program software is standardized.
