top and bottom heading method

Confronted with accidents in a shallow-buried weak tunnel through old road using the bench excavation method,such as great subsidence and cracks in the ground surface as well as those in the preliminary support,a double down-side drifts construction method was presented.

针对某隧道软弱围岩下穿公路段在原台阶法施工中出现地表下沉、开裂等问题,提出双下侧导坑施工方法,分析其传力机制,并应用MIDAS软件建立仿真模型,进一步研究该工法的施工性态。
