基于自动化监测技术的地铁沉降数据一致性分析

The consistency of the subway subsidence data based on automatic monitoring technology

沉降监测是地铁安全监护的重要内容,通常采用人工精密水准测量与自动化静力水准系统。随着城市轨道交通网的日益扩展,自动化监测技术的应用更趋普遍。因两种方式的监测点布设于不同的隧道结构位置上等原因,使沉降数据有时存在差异。结合工程实际,分析了人工和自动化监测数据不一致的主要表现形式,并提出了相应的改进措施。

Subsidence monitoring is an important component of the secudty monitonng regime for subway tunnels, and is usually achieved using either artificial precise leveling or automated static leveling systems. Alongside the expansion of the urban rail transportation network, the application of automatic monitonng technology is becoming increasingly popular. However, subsidence data may sometimes differ because the observation points of the two monitoring systems are at different positions within the tunnel structure. Based on an engineenng case, this paper analyzes the major patterns of inconsistency in data fTom artificial and automatic monitoring approaches, and suggests appropriate improvement measures.
