在现场锚注加固试验基础上,根据注浆量统计结果,对软岩硐室围岩间空隙分布进行反分析,采用FLAC建立相应数值分析模型,分析了不同支护围岩关系对支护体内力和围岩自承能力的影响以及支护体的变形破坏特征,得出的结论对改进煤矿大断面软岩硐室支护工艺有一定意义.图6,表2,参5 Based on the grouting test results, based on the statistical results of grouting volume, the gap distribution of surrounding rock in soft rock chamber was analyzed inversely. The FLAC was used to establish the corresponding numerical analysis model. The relationship between different supporting rock and surrounding rock was analyzed. Force and self-bearing capacity of surrounding rock as well as the deformation and failure characteristics of the support body, the conclusions drawn are of some significance for improving the soft rock chamber support technology for large-section coal mines.
