摘要

This paper main introduces the hydro geological of the 300 m high arch dam named Xiluodu, combined with drilling hole and injecting water experiment, seepage test, ground water tracing-connect experiment and water-pressure test in hole, carries detailed exposition about permeability, seepage characteristics of the dam bedrock, ground water as well as its dynamic change, the basalt construction as well as its influence to permeability, relation between dam area crevasse rock mass permeability and the decency discharge, dam area Mao Kou calcareous rock hydrology geology characteristic and the seepage characteristic. Based on hydrogeology and permeability of dam area, seepage stability measures are made, this paper gives analysis result about three-dimensional seepage analysis program for the complex foundation and comparison to Ertan project,which will provide experience for other engineering.
