地表沉降监测指导浅埋大跨度隧道施工案例分析

Case analysis of shallow buried large span tunnel construction guided by ground surface settlement monitoring

针对大跨度浅埋隧道施工面临的难题,以阳灵隧道出洞口浅埋段信息化施工为例,对施工监控量测方案作了介绍,并阐述了地表沉降变形特征,通过必测项目监测分析发现,监控量测能较好的指导大跨度浅埋隧道施工,可为类似工程施工提供参考。

According to the construction problem of shallow buried and large span tunnel, with the shallow buried unkennel section construction of Yangling tunnel as an example, introduces the monitoring measurement schemes of construction, and illustrates the features of surface subsid-ence deformation, through the necessary items monitoring and analysis, it’ s founded that monitoring and measurement can guide the construction of shallow buried large span tunnel better and can provide reference for similar engineering construction.
