引松供水工程总干线地应力测试研究
Study on Ground Stress Test of Main Diversion Line of Water Supply Project from Songhua River
摘要
Abstract
The Project of Water Supply from Songhua Lake is the largest water conservancy project in Jilin province.The total length of main diversion tunnel is about 98 km,which is one of the longest pressurized diversion tunnels in China.The tunnel will pass through different lithology layers,so the geological conditions are complex.By using hydrodynamic fracturing method,the ground stress test is carried out to study the characteristics of ground stress field of tunnel,and the maximum and minimum horizontal principal stresses and the direction of horizontal principal stress are obtained.The results show that the ground stress in test area is medium-low level.From the point of view of ground stress,the choice of tunnel axis is more favorable to the stability of surrounding rock.关键词
