| 摘 要： | 利用离散元－边界元耦合模型对溪洛渡工程地下厂洞室群静，动力响应进行了分析，对离散元模拟地下结构的一些问题进行了探讨，得到了一些结论：离散元模型能够很模拟地下洞室群的变形，通过与边界的耦合，可以模拟辐射阻尼的影响，由于辐射阻尼的影响，地下洞室群的地震响应比地面结构小很多。

| Abstract: | Employing the coupling model of distinct element boundary element,the static and dynamic analysis of underground power plant of Xiluodu Project is conducted.Some problems in distinct element simulation of underground structure are discussed.The conclusion that the distinct element method can simulate the deformation of underground structures is drawn.The effects of radiation damping can also be modeled,if distinct elements can be coupled with boundary elements.The seismic responses of underground structures will be much smaller than that of structures on the ground surface,due to effects of radiation damping. |
