苏联国家建设委员会地基和地下建筑科学研究院详细地制定了鉴定坑道围岩应力状态、稳定性以及静荷载与地震作用下隧洞衬砌应力的计算方法。根据这些方法编制了电子计算机程序,可供设计单位从事实际计算时使用。本文列举了利用这些方法为罗贡水电站隧洞开挖和衬砌所作的一些计算成果。 (一)考虑岩体初应力主轴因岩层倾斜而呈倾斜状态时,坑道周围非弹性变形区假定边界的确定。本文将坑道围岩内应力不符库伦—摩尔(Mopa)强度条件的区域称为非弹性
The Soviet National Construction Commission foundation and the Institute of Underground Building Science developed in detail the identification tunnel surrounding rock stress state, stability and static load and earthquake calculation of tunnel lining stress. According to these methods, electronic computer programs are compiled and can be used by design units in actual calculation. This article lists some of the calculation results of tunnel excavation and lining by using these methods. (I) Considering the initial stress of rock mass When the main shaft is inclined due to the rock slope, the boundary of the inelastic deformation around the tunnel is assumed. In this paper, the area where the stress in the tunnel surrounding rock does not conform to the Mopa strength is called inelastic
