The invention relates to a goaf site high-speed railway subgrade settlement monitoring device. The device comprises a laser signal receiving wall, an automatic level adjusting platform, a laser transmitting port A, a laser transmitting port B, a circuit receiving module board, a laser receiver M and a laser receiver N, wherein a microcomputer receiving control system and the laser receiver M are embedded in the front end face of the laser signal receiving wall; the laser transmitting port B is connected with the ground plane through the automatic level adjusting platform; and the laser transmitting port A, the laser receiver N and the circuit receiving module board are all embedded in the side surface of a train. The settlement observation method comprises the five steps of subgrade observation equipment positioning, laser signal receiving wall construction, train body observation structure assembling, settlement observation and settlement judgment. According to the invention, the purpose of accurate detection of settlement monitoring of a goaf site subgrade is realized on the premise of relatively low cost; and meanwhile, real-time judgment and early warning on an operation state of the train under the condition of uneven settlement in a comparison site are realized.

    本发明涉及一种采空区场地高速铁路路基沉降监测装置,包括激光信号接收墙、自动水准调节平台、激光发射端口A、激光发射端口B、电路接收模块板、激光接收器M、激光接收器N,一个微机接收控制系统及激光接收器M嵌于激光信号接收墙前端面,激光发射端口B通过自动水准调节平台与地平面连接,激光发射端口A、激光接收器N及一个电路接收模块板均嵌于列车侧表面上。其沉降观测方法包括路基观测设备定位,激光信号接收墙建设,车身观测结构装配,沉降观测,沉降判断等五个步骤。本发明实现在耗费较小的成本代价前提下实现采空区场地路基的沉降监测进行精确检测的目的;同时实现对比场地内不均匀沉降情况下对列车运营状态实时判断预警。
