引汉济渭工程黄三隧洞地下水渗流同位素综合示踪探测分析研究
Analysis on comprehensive isotopic-tracing detection of underground water seepage in Huangsan Tunnel of Hanjiang River to Weihe River Valley Water Diversion Project
摘要
Abstract
The lithology of the deeply buried water conveyance tunnel of Huansan Section for Hanjiang River to Weihe River Water Transfer Project is complicated and variable under a quite complicated hydrogeological condition.In order to deeply analyze the hydrogeological condition of Huangsan Section,the method of comprehensive underground isotopic-tracing detection is adopted for the in situ testing and the indoor sampling analysis made on the areas of the drillings along the line of Huangsan Tunnel,Daping Tunnel,Liangxinhe Rover,Shapinghe River,etc.Through the comprehensive analysis made in the aspects of temperature,conductance,water chemistry,environment isotope,groundwater flow rate,etc.,the conditions of groundwater recharge,runoff,discharge,etc.and the hydraulic connection as well as the connectivity therein are evaluated in combination with the basic works of hydrogeological survey and experiment concerned.The result show that there are water-rich areas surrounding southern and central Huangsan Tunnel,in which groundwater is mainly affected by the meteoric water;the surrounding rock can be divided into secondary water-rich area,weak water-rich area and water-poor area,accounted for 7.9％,15.4％ and 76.7％ in the tunnel.The actually exposed water burst amount is coincided with that from the prediction made in the original design,and then the availability of the method of the comprehensive isotopic-tracing detection is verified as well.The result obtained herein has a certain reference value for the similar project.关键词
