摘要
通过对隧道坍塌的机理进行分析,及时采用了强支护,对隧道不同坍塌部位分别采取管棚法、小导管注浆法及二次衬砌加强及回填法等进行了处理,取得了理想的处理效果。
According to the analysis of the mechanism of collapse in tunnels,the paper adopts the strong support promptly,and undertakes some treatment,such as the tunneling with pilot pipes,the small pipe pouring method,the secondly lining strengthening and the backfilling method,and better effect is achieved.
