复杂岩基上重力坝的深层抗滑稳定问题是一个极其复杂的工程问题,许多因素彼此错综地互相影响着.目前我们还没有弄清楚各个影响因素之间本质上的联系.无论是纯摩公式还是剪摩公式,单用一个“安全系数”是无法表征坝基岩体的深层抗滑稳定性的.因为刚体极限平衡法的致命弱点是,它只考虑滑裂面上的静力平衡条件,没有校核达到这种极限平衡状态时的应力和变形情况.
The problem of deep anti-sliding stability of gravity dams on complex rock foundations is an extremely complex engineering problem. Many factors interact with each other in an intricate manner. At present, we have not yet ascertained the essential relationship between various influencing factors. In addition to the shear formula, a single “safety factor” cannot be used to characterize the deep anti-sliding stability of the dam foundation. Because the fatal weakness of the rigid body limit equilibrium method is that it only considers the static equilibrium conditions on the slip surface. Check the stress and deformation when reaching this limit equilibrium.
