铜锣山隧道区岩溶特征及地下水文分析
|
摘要
南大梁高速公路铜锣山隧道处于岩溶地区,而一般山区岩溶工程地质条件较复杂,勘察难度大。通过加大对隧道岩溶区的调查研究,采用区域地质环境条件分析、岩溶特征分析、岩溶水文地质条件的综合分析法,全面阐述了隧址区的岩溶发育特征和地下水文分布规律。
Tongluoshan Tunnel of Nanchong—Dazhu—Liangping Highway locates in karst area,while the engineering geological conditions are complicated in mountainous karst areas generally and the investigation is difficult. With intensified investigation on the karst area of Tunnel,the comprehensive analysis method,including the analysis of regional geological environment,karst characteristics and karst hydrogeological conditions,was used to explain the karst development characteristics and groundwater hydrological distribution law in the tunnel zone.
