各类软弱结构面,如断层、煌斑岩脉、层间挤压带、深部裂隙等,会对拱坝坝基及坝肩稳定产生不利影响。本文以某高拱坝为例,通过建立三维有限元模型,研究复杂地质地基条件对大坝应力、位移以及坝肩稳定性的影响。由分析得,在正常蓄水位工况下,位移符合拱坝的一般规律,拉、压应力与容许拉、压应力相比偏大。采用刚体极限平衡法对坝肩进行稳定校核。选取了6 个不同高程的拱圈进行校核,均满足规范要求。

There are many different kinds of weak structural planes in the abutment rock mass like faults,lamprophyre dike,inner layer compressed zone and deep-seated fracture.All of these are disadvantageous to the stability of the dam abutment and foundation.Taken a high arch dam as an example,a three-dimensional finite element model is established to study the efforts of the complex geological conditions of the dam stress,displacement and abutment stability.According to the result,the changes in displacement meet the general law of arch under the working condition of the normal storage level.Tensile stress and compressive stress is larger than the allowable value.Rigid body limit equilibrium method is used to check the stability of the abutment.Six different elevations of the arch are selected.All of them meet the stability requirements.
