摘　　要：以山东某地下水封石油洞库工程为例,利用Unwedge程序搜索洞室中层可能形成的块体,根据现场调查的各项参数计算块体的稳定性系数,以此评价块体的稳定性及支护方案的有效性。根据洞室中层节理出露趋势,对洞室下层可能存在的块体进行预测,为下层开挖支护提出建议。Taking an underground oil storage project in Shangdong as study case, the Unwedge procedure is used to find out possible block in rock mass and then the stability coefficient of block is calculated based on investigated parameters in order to evaluate its stability and the effectiveness of supporting programs. According to the tendency of joints on middle level of underground rock carven, the possible block in lower level is forecasted and then the supportings for lower level excavation are proposed.
