    ANALYSIS OF A HYDROPOWER STATION DAM ON BASALT CONFINED WATER CHARACTERISTICS AND INFLUENCE

    • 摘要: 某电站玄武岩坝区地质条件复杂,研究表明坝区玄武岩裂隙含水系统具有不均匀性、各向异性和多级次性特点。本文结合玄武岩裂隙特征和渗透系数确定方法,给出了评价岩体渗透性的尺度。勘探揭露河床右侧及右岸岸坡发育承压水,据埋藏条件和水化学成分可分为上部承压水和下部承压水,分别对其分布范围特征;承压水水位、流量及动态特征;承压水水化学特征;贮存环境特征;补给、径流、排泄特征等方面进行阐述,分析了承压水对建坝影响,根据分析成果采取针对性处理措施,取得了较好的效果。

       

      Abstract: A power plant in basalt complex geological conditions, exploration and development of the right to expose the bed on the right bank of confined water. Research shows that the fractured basalt aquifer system with the inhomogeneity, anisotropy and multi-level characteristics. In this paper, the method of evaluating the permeability of rock mass is given based on the fracture characteristics and permeability coefficient. According to the burial conditions, the chemical composition of the water can be divided into upper and lower water pressure of confined water, respectively. The distribution characteristics of confined water level and discharge, the dynamic characteristics of confined water, water chemistry characteristics, storage environment characteristics, supply, runoff and discharge characteristics are discussed, analyzed the influence of confined water on the dam, take targeted treatment measures based on the analysis results, achieved good results.
