摘要
以山西省某混凝土面板堆石坝为例,采用子单元法计算了其在极端工况下的渗流特性,结果表明大坝各组成部分在极端工况下不会出现渗透破坏。最后,对各材料的渗透系数进行了敏感性分析,垫层的渗透系数较其他部分为敏感,因此必须加强对垫层工程质量的严格控制。
Taking a concrete face rock-fill dam in Shanxi Province for example,the seepage features under extreme conditions are calculated here by using a subunit method.The results show that there wouldn＇t appear the permeated destroy in the component parts of the dam.At last,the sensitivity analysis is made for the hydraulic conductivity of the each material.The permeability coefficient of the under-layer is better sensitive than other parts.So,the construction quality of the under-layer must be strengthened.
