隧道采用新奥法原理施工时,利用监控量测获得隧道净空变化观测值,可以很好的了解隧道围岩体内的应力动态过程及发展趋势、围岩的稳定性、支护的合理性以及确定二衬的施做时间等。通过超前地质预报和监控量测为玉希莫勒盖隧道的设计与施工提供依据,研判隧道围岩稳定性情况。 When the tunnel is constructed according to the new Austrian law, the monitoring observation can be used to obtain the observation value of the change of the clearance of the tunnel so as to get a good understanding of the dynamic process and development trend of the surrounding rock in the tunnel, the stability of the surrounding rock and the rationality of the support Second lining of the implementation time and so on. By means of advanced geologic forecasting and monitoring surveying, it provides the basis for the design and construction of Jade Molygai Tunnel and studies the stability of tunnel surrounding rock.
