| 摘 要： | 应用UNWEDGE软件结合青岛某LPG地下储库水幕廊道1K0+125～145段进行关键块体的搜索计算,得到4个可移动块体。其中,块体1位于廊道底部,为自稳块体;块体4、5分别位于廊道左右边墙,安全系数为1.945和3.385,基本满足自稳要求;块体8位于廊道顶部,体积和重量均较大,安全系数取为0,需采用特别支护和分析结果提出支护方案。从支护前后结果对比可以看出,块体安全系数提高幅度较大,块体8在锚杆支护和锚喷支护情况下安全系数分别为1.278和6.406,喷射混凝土对于提高块体安全系数作用明显,支护方案满足工程安全性要求。

| Abstract: | The research and calculation of the key block of 1K0+125~145 section in water curtain gallery at Qingdao LPG underground storage have been done using UNWEDGE software,and obtained four removable blocks.Block 1 was a self-stable block and located at the bottom of the gallery.Block 4 and block 5 located at the left and right walls separately,with the security factors of 1.945 and 3.385,can meet the basic requirements of self-stable.Block 8 located on the top of the gallery with large size,heavy weight and a s... |
