| 摘 要： | 在地下洞室开挖中,由于岩体中原有结构面的存在,再加上洞室开挖后应力重新分布与集中,以及爆破作业的影响,在洞室顶部一定范围内会形成岩石松散圈.某水电站地下厂房开挖有中导洞先行和两侧导洞先行两种方案,利用有限元方法并参照类似工程,确定了中导洞先行的顶拱层开挖方案.

| Abstract: | In the engineering of underground cavern excavation,due to the original structure in rock mass,plus stress redistribute and concentrate after the excavation of cavern,and again,the influence of explosive,thus,the rock loose circle will form inside certain limits of the top cavern.The excavation of a hydropower station underground workshop has two schemes,one is middle drift first and the other one is bilateral drift first.In order to obtain the better method,this thesis utilizes finite element method and re... |
