According to the design code of concrete gravity dam, starting from the actual situation, the blade calculation and design calculation are carried out in this design. The reliable and simple construction diversion solid gravity dam is adopted for calculation, and the stability calculation and stress calculation analysis are carried out in combination with the load point conditions, so as to obtain the best configuration file which is safe and economic; The construction of the dam will play an important role in flood control, irrigation and power generation. It will also play an important role in promoting the development of local industry and agriculture and solving the problem of power supply shortage in the power system.
