摘要
在隧道“新奥法”施工中,其围岩稳定性监测是非常重要和必要的一个施工环节.文中利用光纤光栅传感器,动态跟踪监测开挖隧道围岩的应变,反演洞周收敛位移,从而有效地判断围岩的稳定性.该方法操作简单、数据可靠.
During tunnel constructing on the basis of ＂NATM＂, monitoring of its surrounding rock＇s stability is very important and essential. In This paper, fiber grating sensors are utilized to monitor the surrounding rock＇s strain. Then the clearance displacement can be calculated and the stability of the country rock can be judged. This method is simple and feasible. Collected data are reliable.
