关中地区引调水线路隧洞工程主要工程地质问题分析及对策

Analysis and Countermeasures of Main Engineering Geological Problems in Tunnel Engineering of Water Diversion Line in Guanzhong Area

近年来由于关中地区经济迅猛发展和人口不断增长,水资源供需之间的矛盾日益加剧,引调水工程对关中地区社会经济的快速发展起着关键作用。以东庄水利枢纽供水工程和引汉济渭工程为基础,介绍了关中地区引调水线路隧洞工程的主要工程地质问题,对在关中地区输水隧洞所涉及的一些重要工程地质问题进行阐述,如洞室围岩类别及稳定性、洞室突水涌泥、放射性及有害气体等。并结合实践经验提出具有针对性的解决措施,对指导工程勘察设计以及建设具有重要意义。

In recent years,due to the rapid development of economy and the continuous growth of population in Guanzhong area,the contradiction between supply and demand of water resources is becoming more and more serious.The water diversion project plays a key role in the rapid development of social economy in Guanzhong area.Based on the water supply project of Dongzhuang Water Conservancy Project and the Hanjiang-to-Weihe River Water Diversion Project,this paper introduces the main engineering geological problems of the tunnel project of the water diversion line in Guanzhong area,and expounds some important engineering geological problems involved in the water conveyance tunnel in Guanzhong area such as the type and stability of the surrounding rock of the cavern,the water and mud inrush of the cavern,radioactivity and harmful gas.Combined with practical experience,it puts forward targeted solutions,which is of great significance to guide engineering survey design and construction.
