Displacement back analysis of embankment dam using genetic algorithm

Dam safety evaluation of the embankment dam is very important in the dam operation and its management, and its safety evaluation must be based on the observation data during its operation. The genetic algorithm is applied to parameters back analysis of the soils in the dam body. According to the charactors of the embankment dam observation data, a method which is suitable to the back analysis of the soil dam is supposed, and a computer program EDBAGA based on optimatical genetic algorithm is developed. The application of EDBAGA on Baiguishan dam shows that the accuracy of the back analysis is affected by observation data number and a multi-section analysis method is suggested to compensate the deficiency of the observation data.
