| Abstract: | Combined with the construction technology of shallow-buried section at the entrance of the second double Qilianshan railway tunnel, the paper expounds the construction scheme of arch wall long pipe shed combined with separated excavation for the shallow-buried section in plateau permafrost region which can not only effectively reinforce the surrounding rock, but also ensure the stability of the tunnel structure. Meanwhile, the scheme is relatively simple, and it can greatly reduce the construction cost and improve the work efficiency. |
