摘　　要：拾荷隧道与广梅汕铁路斜交 ,隧道拱顶距铁路已建成的路肩挡墙基础底只有 10m ,由于修筑铁路开挖路堑以后山体失稳 ,造成表土坡残积层崩塌 ,因此 ,拾荷隧道下穿铁路段成为施工中的技术难点 ,设计与施工采用长管棚注浆术及相关新工艺 ,达到了减震。Owing to the landslide and unsteady slop because o f the railway cut,the section of Shihe tunnel beneath the railway is very difficu lt to construct. In this engineering field,the long tubular shanty grout inject ion and some new relevant techniques are adopted.It proves that it is effective to reduce the vibration and strengthening surrounding rock.

关 键 词：隧道下穿铁路 长管棚注浆 施工技术 实例
