本试验利用自制的地质力学模型材料(MSB),在窑洞式地下厂房的立式平面应力模型的周边上,按实际主应力方向进行加载。成功地模拟了原始地应力场,得出了洞室在实际开挖过程中围岩应力变化、洞室变形状况及破坏形态。
In this experiment, the self-made geomechanical model material (MSB) was used to load in the direction of the actual principal stress on the periphery of the vertical plane stress model of the underground tunnel building. The original ground stress field has been successfully simulated, and the stress of surrounding rock in the excavation of the cavern has been obtained. The cavern deformation and failure modes have been obtained.
