本业水库扩建工程库区工程地质条件及渗漏分析

摘要

The planning engineer is regional tectonic developed,which is distributing intensively developed karst in reservoir area of carbonate rock,the range of the height of low valleys is not large. According to achievement of engineering geological mapping,investigation and test data, in the basis of analysis regional fault,stratum and rock character,there are not throughout the reservoir of conducting-water structure and solution corridor in the extension proiect,there are large thickness of impervious stratum. So the possibility of leakage of reservoir water is small,the engi-neering geological conditions of the reservoir is good in the extension proiect.%拟建本业水库工程区域构造发育，库区分布强岩溶化碳酸盐岩地层，存在高差不大的低邻谷，在综合分析区域断层、地层、岩性的基础上，根据工程地质测绘，结合勘查及试验资料分析认为，扩建工程未形成贯穿库外的导水构造及溶蚀通道，库区与低邻谷之间存在雄厚的阻水河间地块，扩建水库库水向外渗漏的可能性小，具备扩建的工程地质条件。
