| Abstract: | Based on the field monitoring data of dam deformation and combining with calculation and analysis of finite element model, the deformation modulus of dam and foundation are obtained by inversion. A combined model is established by using a feedback parameter. The paper proposes a reliable new finite element model and an approach for the analysis of dam structure in large-scale hydraulic engineering. The results show that the proposed method is accurate, reliable, and practical. |
