Abstract:Based on the monitoring data about the crest displacement of a gravity dam, the component of horizontal displacement caused by impounded water was separated by progressive regressive method. At the same time, an inverse problem about elastic parameter of dams and basic rocks identification using improved genetic algorithm was analyzed as an optimization problem. Also, during the inverse calculating process, contact elements were used to simulate the longitudinal joints of the dam. It is shown that the methods proposed are coincident better with the actual structure, and the results of the inverse analysis are reasonable and reliable in high degree.
