沉降自动监测系统在深厚岩盐路基中的应用

Application of Automatic Settlement Monitoring System in Deep Rock Salt Subgrade

针对目前路基沉降监测主要以人工现场监测为主、监测设备环境适应性差、与工程施工相互干扰、精度受人为影响因素大等技术现状,研发出了能实现远程监测与管理的路基沉降自动监测系统,阐述了系统的工作原理、组成结构、技术指标等,并结合依托工程,对沉降自动监测系统进行了现场测试。结果表明,该路基沉降自动监测系统体积小、精度高、不干扰施工和交通,能实现远程监测与管理,适用于恶劣自然环境下的路基总沉降和分层沉降实时监测。

Aiming at the technical problems of subgrade settlement monitoring,such as requiring artificial field monitoring, poor environmental adaptability of monitoring equipment and interference with the construction and great human impact on precision,etc.,an automatic monitoring system of subgrade settlement is developed, which can realize remote monitoring and management. At the same time, the operating principle,structure and technical indexes of the system are described and the field test of the system is carried out based on the project. The results show that the automatic settlement monitoring system of the subgrade is small in volume,high in accuracy,does not interfere with construction and traffic and it can realize remote monitoring and management and be applied to the real-time monitoring of the total settlement and layered settlement for subgrade under harsh natural environment.
