| 摘 要： | 某水电站布置有大型的地下洞室群,其规模在国内外已建和拟建的工程中都是十分罕见的。总体上说,地下厂房区岩体质量较好,但由于多期的构造作用,在厂房区岩层中发育有不同级别的结构面,对围岩的稳定性有一定影响。对此,本文运用围岩分类法和数值模拟法分析了厂房开挖后围岩的整体稳定性,然后运用UNWEDGE软件对主厂房顶拱部位的不稳定块体进行了分析评价。

| Abstract: | The underground chamber group, where a big power station is designed, is so large that it is rarely matched throughout the world. On a whole, the quality of rock mass in the chamber group is better. Because of tectonism, there are several structure planes in the rock mass. Rock mass stability surrounding the large-scale underground cavern swarm was analyzed with the rock mass classification and numerical modeling methods. And then the block geometric parameters and stability were calculated with UNWEDGE software. |
