| 摘 要： | 山岭隧道进洞是隧道施工的开始,也是关键环节,由于施工扰动造成地应力的重分布,成为洞口边坡滑动或者洞口浅埋段塌方的诱导因素。因此,合理的施工方案与施工计划对控制洞口边坡以及浅埋段的稳定性至关重要。文章结合江西省景婺黄(常)高速公路新建隧道洞口施工过程中的沉降问题进行了探讨,并结合施工监控与反分析预测技术提出了一些针对性的工程技术措施,为工程的顺利进行提供了技术保障。

| Abstract: | Excavating into a mountain tunnel is the beginning and an important process of construction.Ground stress undergoes redistribution that sometimes induces the landslide and collapse at the tunnel entrance.Thereupon rational construction scheme is quite important for ensuring the stability of the tunnel entrance and the shallowly embedded section.The ground settlements caused by the excavation of Xinjian tunnel on Jingwuhuang(Chang) highway were discussed in detail in this paper.Some engineering measures were taken combined with construction monitoring and the technology of back analysis.Results of the research provided technological guarantee for the smooth completion of the project. |
