基于物联网技术的路基沉降监测系统应用研究

Monitoring system of embankment settlement based on Internet of Things technique

软土地区路堤填筑过程中路基沉降监测对于指导施工和设计具有重要实际价值,而人工监测具有成本高、连续性差、易受环境影响等局限性,已越来越不适用工程建设的需要。本文以杭州绕城西复线湖州段软基处理工程为依托,创新性地采用“物联网+”技术进行路基沉降实时监控。该系统实现了高速公路施工期和运营期路基沉降的远程、实时、高精度监测和预警,为准确预测路基沉降发展、指导施工和道路运维提供支持。

It is significant that for guiding construction and design based on the monitoring work of embankment over soft soils. However, due to the limitations of high cost, poor continuity and vulnerability to environmental impacts, manual monitoring has less met the requirements in practice. This paper introduces an application of remote monitoring system for settlement which has been used in the ground improvement project at Huzhou Section in Hangzhou Beltway. The engineering application shows that this system is able to achieve real-time and remote tracking of monitoring data during embankment construction, so as to conduct a real-time analysis of embankment settlement, and to provide supports to construction and maintenance of roadway.
