摘　　要：为了保证高速公路的安全正常运行,必须要掌握下穿隧洞施工对地层的扰动和支护结构的受力情况。结合滇中引水工程香炉山隧洞实体工程的现场监控量测,介绍了相关监测方案及其监测结果。成果显示:隧道施工过程中,围岩变形趋于稳定,钢拱架和二衬内力的安全系数均满足设计规范要求,说明隧道施工方案合理,工程结构稳定可靠,所用传感器有效完成相关监测任务。In order to ensure the safe and normal operation of highways,it is necessary to grasp the disturbance of the strata and the stress situation of the support structure caused by the construction of underpass tunnels.Based on the on-site monitoring and measurement of the Xianglushan Tunnel physical project of Central Yunnan Water Diversion Project,this paper introduces the relevant monitoring schemes and their monitoring results.The results indicate that during the tunnel construction process,the deformation of the surrounding rock tends to stabilize,and the safety factors of the internal forces of the steel arch and secondary lining meet the design specifications.It indicates that the tunnel construction plan is reasonable,the engineering structure is stable and reliable,and the sensors used effectively complete the relevant monitoring tasks.
