摘要
隧道下穿河流段处于浅埋段,不宜采用爆破开挖,因此采用悬臂掘进机开挖方法来减少扰动.文章结合莲花山隧道工程,提出下穿河流浅埋段隧道悬臂掘进机施工工法,避免隧道下穿河流浅埋段地层发生坍塌及涌水,减少开挖带来的扰动,顺利通过浅埋段,为隧道建设提供新的施工技术.
Abstract
The section under the river of the tunnel is in the shallow buried section,and blasting excavation is not suitable,so the cantilever excavation method is used to reduce the disturbance.Combined with the Lianhuashan tunnel project,the construction method of the cantilever boring machine of the tunnel under the shallow buried section of the river is proposed,which can avoid the collapse and water inrush of the shallow buried section of the tunnel under the river,reduce the disturbance caused by excavation,and smoothly pass through the shallow buried section,so as to provide a new construction technology for the tunnel construction.
