摘要
对于深埋长大隧道,地应力情况非常复杂,为了合理指导施工方法,需要在孔内进行三维地应力测量。首先介绍了三维地应力测量的原理,然后应用该方法在西康高铁进行测量,获得了较好的结果。实践证明,单孔水压致裂三维地应力测量方法能够方便快捷地获得孔内三维地应力数据,测量成本相对较低,测量结果真实可靠。
For the deeply buried long tunnel,the condition of geostress is especially complex.It is necessary to conduct 3D geostress measurement,so as to guide the construction method reasonably.Firstly,this paper introduces the principle of three-dimensional ground stress measurement,and then adopts this method to measure the Xikang high-speed railway.Finally,good results are obtained?The practice shows that this method can acquirethe three-dimensional geostress data in the hole convenientlyand quickly.Besides,the test cost is relatively low and the test results are reliable.
