摘要
EH4电导率成像系统在复杂地质条件下对构造、岩溶等不良地质现象的工程勘测,具有勘探深度大与分辨率高的特点,从而为水电隧洞工程勘察和评价提供了有效手段及依据。通过在吉沙水电站引水隧洞工程勘测中对地质灾害准确预报的实例说明,该系统是在特殊景观条件下先进的工程地质勘探手段。
EH4 electric conductivity imaging system is characterized by deep reaching exploration and high resolution when applied to engineering reconnaissance for unfavourable geology such as structure and karst landscape under complicated geological condition therefore it provides an efficient tool and basis for reconnaissance and evaluation of hydroelectric tunneling. The system have been proven to be a advanced geological prospecting tool for civil engineering, exampled by the precise forecasting for geological disasters during a reconnaissance for water guiding tunnel in Jiesha Hydroelectric Station.
