stress relaxation method
Examples
- Obtain these chief research achievements . ( 1 ) the method of hydraulic fracturing , kaiser effect experiment and the finite element numerical simulation computation results , the direction of maximum horizontal principal stress intersect the small - angle of tunnel axial line , it is favorable to the stability of tunnel peripheral rock ; according to the test rust of field stress - relief method , at the present time , zhe gu mount tunnel have n ' t access to high crustal stress site , maximum principal stress magnitude is 17mpa ~ 20mpa
主要获得以下研究成果： ( 1 )综合水压致裂法、室内岩石kaiser效应试验和有限元数值模拟计算研究成果，最大水平主应力方向与隧道洞轴线小角度相交，对隧道围岩稳定性有利；根据现场应力解除法测试结果，目前鹧鸪山隧道尚未进入高地应力段，最大主应力量级为17mpa 20mpa 。
