| Abstract: | The collapse treatment scheme for the Dahualing right-line tunnel of the Zhangjiakou-Chengde Expressway is presented in detail in the paper, which includes the following. （1） the general guide lines for tunnel collapse treatment in waterproofing, stabilizing the tunnel foundation, strengthening surrounding rock, and carefully planned tunnel excavation; （2） specific scheme and technical measures for ground surface waterproof treatment, tunnel foundation stabilization, short space Ⅰ-type steel tunnel arch supports, small pipe advanced grouting, adding new supports while deformed primary supports are removed, short advance space arc excavation with up bench core soil remained, providing arch feet locking bolts, primary support quickly ring-closed, and pouring permanent lining as soon as possible. The technical measures described in the paper may serve as a good reference for other similar projects. |
