| Abstract: |
| Cemented Sand and Gravel(CSG) dam is a new type of environmentally friendly dam proposed in recent years, in which the foundation is the main influencing factor in the design of high dams.In order to explore the influence of foundation on the forces of cemented sand and gravel dams, finite element force analysis of Cemented Sand and Gravel dams under different foundations was carried out based on damage theory with the help of numerical simulation methods. The calculation results show that：(1) With the same dam foundation material, the less cementing material there is in the dam, the higher the damage potential of the dam and the dam foundation. (2) For the same dam material, the greater the stiffness of the foundation, the greater the damage at the heel of the dam and the less the damage at the dam site. Therefore, in the structural design of Cemented Sand and Gravel dams, appropriate material analysis of the dam body and foundation is required to reduce the structural damage of the dam. This work could provide a theoretical basis for the design and application of Cemented Sand and Gravel dams. |
