南水北调西线深埋长隧洞引水工程的水文地质调查方法

针对南水北调西线一期工程区复杂的地质、地貌条件和工作条件,采用了以查明工程水文地质问题为目的的高寒区遥感水文地质综合调查方法.多时相、多层次的遥感解译是整个调查的基础,遥感解译与地面调查的密切结合是调查精度的保证.采用小流域水文图分析与泉、溪测流结合,研究地下水径流量的分布.通过多种水文地质试验,结合地质地貌环境的综合分析获得岩体透水性参数.旨在为水文地质调查工作提供若干新的思路.

Investigation Methods for Hydrogeological Conditions in the Western-Route of the South-to-North Water Transfer Project with Deep Buried Tunnel

Along the Western Route of the South-to-North Water Transfer Project,the geologic, geomorphic and climate conditions are very complicated and the field investigations are very difficult to be performed. An integrated remote sensing method is proposed for surveying the hydrogeological condition in the cold upland region at understanding the engineering hydrogeological problem. The remote sensing explanation with the data of multi time phase and multi strata sequence is the basis work, and ground work can improve the survey accuracy, The permeability of rock mass is researched based on several different types of hydrogeological field tests with the consideration of hydrogeological and geomorphic environmental situation. The comprehensive research of hydrogeochemistry and environmental isotope is also done as a very important work for the engineering hydrogeological survey with complicated tectonic surroundings, The research work is hoped to provide several new ideas for the survey work of the hydrogeological conditions.
