力条件是σ2≈σ1,所以,在单轴应力状态下的围岩也更容易出现破坏. 图13 一般地应力条件下洞室开挖前后应力莫尔圆[4] Fig. 13 Mohr circle under general geostress condition before and after excavation[4] 图14 猴子岩应力条件下洞室开挖前后应力莫尔圆[4] Fig. 14 Mohr circle under Houziyan’s geostress condition before and after excavation 3.2 地质构造与围岩开裂的关系 施工地质编录资料显示(见图15),主厂房上下游侧岩锚梁-拱肩之间边墙部位岩体质量较好,其中上游侧岩锚梁-拱肩部位Ⅲ1类围岩占87.7%,Ⅲ2类围岩占12.3%；下游侧岩锚梁-拱肩部位Ⅲ1......
and underground water level is leveled with ground water level and drainage water analysis is applied in the program. Mohr–Coulomb elastic-plastic model is applied in the simulation with calculation... of Mohr–Coulomb model. Therefore, the reasonable setting of initial stress is of vital importance to finite element analysis of geotechnical engineering. In terms of pile foundation, generally speaking......
. The Mohr circles of different confining pressures and strength envelope were drawn, and the cohesion and internal friction angle were calculated. The micro parameters of subsequent virtual tests were.... According to the stress-strain curves of 50, 100 and 150 kPa confining pressure, the Mohr circles and strength envelope are drawn in Figure 5. The shear strength parameters are calculated......
