深埋背斜软层巷道围岩稳定性演化规律研究
The stability evolution law of surrounding rock of deep-buried roadway with anticlinal soft strata
摘要
Abstract
In view of the stability problem of surrounding rocks in the deep-buried roadway with anticlinal soft strata,the evolution law of variables characterizing the stability of surrounding rocks which change with the stress field and roadway axial arrangement angle of α in that deep-buried strata was researched through 70 groups of numerical model and industrial field tests,and the influence of the layout location in deep-buried roadway with anticlinal soft strata and axial angle of roadway on the stability of surrounding rock was revealed.The results have shown that 1) Both the change of the layout location and axial angle of roadway have obvious influence on the stability of surrounding rock in anticline structure,with the latter more significant;2) The stability of surrounding rocks at two wings is higher than that on the ridge of the anticline structure.Therefore,both the position and axial angle of roadway should be taken into account when designing the layout of roadway.关键词
