摘要
应用FLAC3D软件,结合实际工程,考虑混凝土、围岩和锚杆3者变形对岩锚吊车梁受力状况的影响,计算分析了岩锚吊车梁及附近围岩在运行期轮压作用下的工作性态和稳定性,分析了岩锚吊车梁锚杆的受力情况以及吊车梁与岩壁接触面的稳定性,论证了三维有限差分方法用于研究水电站地下厂房岩锚吊车梁的合理性.
Combined with the extended project practice of the underground powerhouse at some hydropower stations, the effect caused by deformation of concrete, rock mass and bolt on a rock bolt crane girder was considered, and the FLAC^30 code was applied to simulate and analyze the wheel load stress state of a rock bolt crane girder on the chamber during the operational phase. The stress distribution of bolts on a crane girder and the stabihty of the interface between rock and crane girder were also investigated. The numerical results suggest that this can be a powerful approach to the stability analysis of a rock bolt crane girder.
