Optimization design of arch dam shape with modified complex method

With the development of arch dam technology, the shapes of arch dam become variable. In order to obtain the reasonable shape, optimization design is the key technology and the important part in the design of arch dam. Based on the engineering example, the geometry model of arch dam is established, the difficulties in the design of arch dam such as more design variables, nonlinearity of the mathematical function and constraint condition, have been solved by using the modified complex method, finally the perfect shape is gained.
