文章结合淳开公路小金山隧道工程施工期间塌方情况,阐明了该隧道塌方原因,从而提出了处治该隧道塌方的WNF方案。同时,在隧道塌方处理过程中,对塌方段的喷射混凝土应力进行了监控量测。根据监测数据,对WNF方案的处治效果进行了分析评价。分析结果表明,WNF法处治小金山隧道塌方是可靠的,可为类似地下工程的塌方处治提供参考和借鉴。
In this paper, the causes of landslip in Xiaokanshan tunnel during the construction of Chunkai Highway are expounded, and the cause of landslip of the tunnel is clarified. A WNF solution to the landslip in the tunnel is proposed. At the same time, during the process of tunnel collapse treatment, the shotcrete stress in landslide was monitored and measured. According to the monitoring data, the treatment effect of WNF regimen was analyzed and evaluated. The analysis results show that the WNF method can be used to treat the collapse of Xiaoshan tunnel, which can provide references for the treatment of landslides in similar underground projects.
