高速公路是服务年限长、整体延伸长度大、行车速度快的特殊线型构筑物.高速公路路基的承载能力与稳定性受路基变形的影响较大,对高速公路进行变形监测具有重要的意义.本文结合某高速公路变形监测工程实践,针对高速公路监测作业环境复杂的特点(要确保线路正常运营,不能封闭公路进行监测作业;路边树密集,无法直接使用静态GPS做平面控制测量;车流量大,桥面振动干扰大等)进行了深入的分析,并提出了应对的措施,对类似监测工程具有借鉴的意义.

The freeway is the special linear long service life, the whole extension length, speed of vehicle structures.The bearing capacity and stability of highway roadbed is greatly affected by the deformation of subgrade, the expressway has important significance for deformation monitoring.In this paper, deformation monitoring of engineering practice with some expressway, according to the characteristics of expressw-ay monitoring environment complex (to ensure normal operat-ion, line can not be closed highway monitoring operations;roadside tree density, can not directly use static GPS plane control measurement; traffic capacity, interference of deck vibration etc.) are analyzed, and puts forward the coping mea-sures, has the reference significance for similar engineering monitoring.
