摘要
以不同的监测仪器,对隧道施工过程中围岩的收敛变形、锚杆作用应力、围岩松动圈等围岩稳定性参数进行观测,为支护设计提供及时准确的反馈信息.并对已施工的一次衬砌、二次衬砌内的应力与变形,以及衬砌间的压力进行观测,取得大量的观测数据,并结合施工过程进行分析,为同类工程提供有益的参考资料.
Different monitors, such as the convergent deformation of tunnel round rock, the anchor stresses, the displacement of round rock, etc,were used to monitor the stability parameters of tunnel round rock in tunnel construction process respectively. These results provided a large of feedback information for the design of shoring system. And the stresses and deformations in the primary and second shoring system, and the pressure between the two shoring system were measured. Based on these datum the author analyzed the mechanic property of shoring system combined the process of tunnel construction. All these provided the beneficial reference for the same kind of engineering.
