摘要: 对横向倾斜地表地层条件下浅埋暗挖法施工引起的地表沉降规律进行研究,以Ⅴ级围岩双线铁路隧道为研究对象,根据不同横向地表倾斜角度(水平、1:20、1:10、1:8)和10 m隧道埋深的条件进行组合,共4个模型,通过对沉降曲线形态、沉降槽宽度、反弯点位置、沉降范围进行分析并初步揭示倾斜地表情况下浅埋暗挖隧道施工引起的地表沉降规律。

Abstract: A shallow buried tunnel is situated in a laterally inclined rock mass. The ground subsidence induced by the tunnel construction is evaluated based on different ground inclination angles: no inclination, 1V:20 H; 1:V:10H and 1V:8H. The double tunnel length has a fixed 10 meters in Class V rock masses. The settlement characteristics of different inclination angle have been evaluated in this paper.
