| 摘 要： | 绩-黄高速佛岭隧道施工期间出现局部塌方，对塌方洞穴面进行喷射混凝土封闭，沿岩面安装钢筋网，用钢拱架支撑，最后采用模筑混凝土和小导管注浆方法加固处理，处理后围岩变形监测结果表明处理方案合理可行，加固效果良好。

| Abstract: | Foling long and large tunnel in Jixi to Huangshan collapsed partially.The caved-in face was prayed concrete to support.Then bar-mat,which was propped up by steel arch,was fixed along the caved-in face. Finally,model-building concrete and little tremie grouting was adopted to reinforce.After a series of measures, surrounding rock deformation monitoring showed that the processing scheme was feasible and the reinforcing effect is good. |
