高密度电法在水文地质调查中的应用实践研究

现代化水文地质调查工作中,高密度电法凭借着工作效率高和生成成本低的优势,在地质找矿与勘察中广泛应用,并获得较强的应用效果。本文以实际案例展开分析,阐述高密度电法在水文地质环境中的调查成果,证明高密度电法应用实效性的同时,通过电极的自由组合提取更加丰富的用电信息,使电法勘探可采用多次覆盖式的测量方法。

The research and demonstration of some major geological problems of Three Gorges Project

The research process,main contents,methods and conclusions for some major engineering geological problems of the Three Gorges Project (TGP) are reviewed and introduced,including dam site selection,regional tectonic stability and seismic activity,stability of reservoir bank and reservoir-induced earthquake.Meanwhile,the above mentioned engineering geological problems are evaluated according to the preliminary test results since TGP operation and impoundment in 2003.
