摘要
抗滑稳定分析是混凝土重力坝设计中一项十分重要的内容,其目的是核算坝体在各种工况作用下沿坝基面或沿地基深层软弱结构面的抗滑稳定安全性。利用有限元法计算坝体的应力和位移,较精确地考虑了坝体所受到的各种荷载及复杂的地质情况,并可以基于此计算结果分析坝体的抗滑稳定性,为坝工设计提供可靠的指导依据。
Stability against sliding of foundation analysis is a very important problem of concrete gravity dam design,the aim is accounting slide stability of dam in a variety of working conditions under the surface along the foundation or along the weak structure of the deep foundation.Using finite element method can calculate dam of the stress and displacement,consider a variety of loads and complex geological conditions,and then can calculate slide stability of dam based on the results,provide a reliable basis for dam design.
