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