Monitoring method and monitoring system for subsurface tunnel settlement

The invention relates to a monitoring method and system for subsurface tunnel settlement, and the method comprises the steps: obtaining a monitoring position based on the length and direction of a tunnel, and installing a total station; based on the monitoring position, obtaining a plurality of reference point positions and installing a plurality of prisms; when a monitoring instruction sent by the monitoring terminal is received, sending a starting instruction to the total station; when the total station receives a starting instruction, test signals are sequentially sent to the prisms at the reference point positions, and a monitoring result is generated; and sending a monitoring result to the monitoring terminal. The tunnel settlement monitoring device has the advantages that the tunnel settlement degree can be monitored conveniently, and workers can obtain tunnel settlement information in time. 本申请涉及一种暗挖隧道沉降的监测方法及监测系统，暗挖隧道沉降的监测方法包括步骤：基于隧道的长度和方向，获取监测位置并安装全站仪；基于监测位置，获取若干基准点位置并安装若干棱镜；当接收到监测终端发出的监测指令时，向全站仪发出启动
