The following are the various methods which can be adopted for carrying out the stability analysis of gravity dams: 1. Gravity Method: This method of stability analysis is also sometimes known as two dimensional methods. In this method, the dam is considered to be composed of parallel sided vertical cantilevers. Each cantilever is considered free to act without any attachment [...]
