| 摘 要： | 乌江渡水电站扩机工程地下厂房系统所在的山体存在着巨大的临空面,厂房系统下游开挖边界与临空面之间的岩柱较薄,地质条件复杂,又受原枢纽大坝拱推力作用,经过平面圾限元计算分析,认为围岩是稳定的,布置是可行的。

| Abstract: | The mountain which the underground powerhouse system located in exists a giant freeing surface. The rock pillar between the underground cavity and the freeing surface of the mountain is thinner, and the geological condition in this region is complicated. In addition, the arch thrust of dam acts to this surrounding rock. According to the results of two_dimensional finite element method, the surrounding rock is stable and the arrangement of undergound powerhouse is availabe. |
