摘要
结合轨道交通的典型基础结构和沉降监测要求,对基于光纤光栅技术的基础结构沉降实时监测系统软硬件进行了设计和现场实施,实现了对典型基础结构沉降的实时、连续、在线、自动检测,实现了结构物随时间发展的相对沉降、不同结构物之间沿线路纵向相对沉降、同一结构物沿线路纵向相对沉降、同一结构物沿线路横向侧倾等状态的监测,并尝试将列车运行时的车致动力响应与基础结构的长期沉降建立联系。系统经现场验证,结果可靠。
Considering the typical structure conditions and requirements for settlement monitoring of metro system in Kunming City, the real-time monitoring system is designed and installed in the field. The monitoring of metro structure settlement is realized with the real-time, continuous, on-line and automatic detection. The monitoring parameters include the relative settlement of one kind of structure with time accumulation, one kind and different kinds of structure along train travel direction, one kind of structure transverse tilt. The relationship between the dynamic response caused by passing trains and the long-term settlement of the structures is monitored. The whole monitoring system is verified by field test.
