摘要
受构造展布及岩性特征的影响,光照水电站坝址区岩溶水文地质条件具明显的东西向展布特征,岩溶发育与地下水动态亦与之相适应。坝址区主要岩溶工程地质问题为隧洞及大坝、厂房基坑岩溶涌水问题。通过对坝址岩溶水文地质特征的分析,可达到预测预报的目的,对下一步地质工作及今后大坝施工具有重要的指导意义。
Under the influence of structure distribution and rock characteristics,the karst hydro-geologic condition of Guangzhao Hydropower Station has an obvious feature of distributing along east to west,and the karst development and the strike of underground water are also bound up with the feature.The main engineering geologic problem is karst blow on tunnels and foundation ditches of the dam and the powerhouse.It could achieve the goal of advance notice to analyze karst hydro-geologic characteristics in dam area,it also has important guiding significance for geologic works and constructing of the dam later.
