摘　　要：为了保障城市隧道工程明挖段施工安全,文章以杭州市艮山东路过江隧道工程下沙明挖段为例,就城市隧道工程明挖段施工风险及监测展开研究。首先介绍了工程背景及特点,然后对工程风险源进行了分析,并提出了风险控制和监测应对措施以及监测工作重点,在此基础上进一步优化了监测项目的选取和基准网的布设,可为类似工程提供参考。In order to ensure the construction safety of open excavation section of urban tunnel engineering, this paper takes the Xiasha open excavation section of Genshan East Road Crossing River Tunnel in Hangzhou as an example to study the construction risk and monitoring of open excavation section of urban tunnel engineering. Firstly, the engineering background and characteristics are introduced, and then the engineering risk sources are analyzed, and the risk control and monitoring countermeasures as well as monitoring work focus are proposed. On this basis, the selection of monitoring projects and the layout of reference network are further optimized, which can provide references for similar projects.
