| 摘 要： | 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.

| Abstract: | Based on bolting and grouting reinforcing test in site,gap between chamber and soft surrounding rock were feedback analyzed according to grouting statistics data,analyses model was set up by FLAC,the effect of relation between chamber and surrounding rock to support internal force and surrounding rock self-bearing capacity were analyzed.Support deformation and destroy feature was analyzed.The conclusion received gave some guidance to improve big section chamber in soft surrounding rock.6figs.,2tabs.,5refs. |
