摘要
在桃园1号隧道工程施工过程中,通过现场监控来掌握隧道围岩与支护结构的工作状况和安全信息,及时预见险情,为调整和修改支护设计参数以及改变施工方法提供重要的依据,从而保证施工安全和降低工程造价。主要从地表沉降、拱顶下沉和周边收敛、钢支撑内力、二次衬砌的应力等几个方面对监控量测的实施与分析进行了介绍。
In construction of Taoyuan No.1 tunnel,the authors master work conditions and safety information of surrounding rock and support structure based on site monitoring to provide reference for adjusting and modifying support parameters in order to ensure construction safety and reduce the cost.Implementation and analysis of monitoring are introduced in detail from ground settlement,vault crown settlement,peripheral convergence,internal force of steel support and stress of the secondary lining.
