| 摘 要： | 围岩呈薄层状、支护结构-围岩未耦合和施工不当导致复杂层状岩层的新扎沟隧道塌方，结合工程实际情况，提出双排超前注浆小导管＋钢拱架＋喷射钢纤维混凝土联合治理塌方区域，在塌方影响区域设置监测站。监测数据显示，围岩变形在一定的时间段内趋于稳定，表明该方案治理复杂层状岩层隧道塌方行之有效。

| Abstract: | Thin layered surrounding rocks, uncoupling of support structure and surrounding rocks, and inappropriate construction resulted in the collapse of Xinzhagou tunnel. According to the actual conditions of the project, it is proposed to treat the collapse area by ap- plying pilot grouting pipes in double rows and steel arch frames combined with steel fiber shoterete. Observation stations are set up in the collapse-affected area. Monitoring data show that the deformation of surrounding rocks becomes stable in a certain period, indicating that the treatment program is feasible and effective for collapse in complex layered rock tunnel. |
