摘要
通过采用全站仪非接触量测洞内变形,结合工程实例分析得出:隧道岩溶发育区以及岩溶段经相应的处理后,可通过对其附近隧道监控量测断面的监测数据进行分析得到围岩变形规律,同时确保处理后的岩溶已消除对隧道安全施工的影响;监控量测断面距工作面距离约为5倍隧道跨度时,变形量基本稳定;通过对隧道变形曲线进行回归拟合,可以更好地掌握及预测隧道围岩变形稳定状态。
Using total station non-contact measurement method and combined with the engineering example analysis shows that through the analysis of monitoring data of the tunnel karst and karst section after the corresponding treatment,which could discusses karst area surrounding rock deformation law, meanwhile ensuring that the karst treatment have been eliminated the influence on the tunnel construction safety; Momtonng anta measuring ~c^u.. 1to,,, L about 5 times the tunnel span,the deformation is basically stable. The deformation stability of tunnel surrounding rock can be better controlled by the regression fitting of tunnel deformation curve.
