小湾水电站坝前堆积体规模较大且坝肩开挖时下侧局部被挖除 ,水库蓄水后堆积体下部将浸于水体中。水库水位的变化也将影响其稳定性 ,故需对其进行稳定性分析和加固方案的分析。作者在先前使用平面离散元法(UDEC)及有限元法对该堆积体在自然状态下的稳定性初步进行二维数值计算与分析的基础上 ,对堆积体又进行了预应力锚索加固方案的三维有限元分析 ,取得了相应的研究成果。
Xiaowan Hydropower Station dam in front of a large body of accumulation and the excavation of the lower part of the excavation of the lower part of the reservoir after the accumulation of body will be immersed in water. Changes in the reservoir water level will also affect its stability, it is necessary to carry out stability analysis and reinforcement program analysis. Based on the previous two-dimensional numerical calculation and analysis of the stability of the pile under natural conditions using the planar discrete element method (UDEC) and the finite element method, the authors carried out the prestressed anchor reinforcement program Dimensional finite element analysis, and achieved the corresponding research results.
