摘　　要：盾构隧道施工中,由于盾构刀盘后面为有压舱,刀盘工作处于“黑箱”状态。为了实时监测盾构掘进过程中刀盘滚刀及刀盘整体的工作状态,研发了一套盾构隧道施工刀盘状态实时监测系统。该系统由传感器、控制与数据传输及算法与显示三个子系统组成;传感器子系统集成了自制的滚刀磨损量与转速传感器、温度传感器、数据采集模块和电源;集成的传感器安装于刀盘滚刀刀箱内,可实时监测滚刀的磨损量、转速与刀盘的温度。采集的数据通过有线或无线传输到中心端,再通过有线方式传送给上位机。上位机软件集成了盾构设计参数及隧道地层参数、盾构施工参数、传感器监测参数,可实时显示传感器采集的参数,并结合地层条件与盾构施工参数综合判定盾构刀盘工作状态,预测滚刀使用寿命。经过实验室测试、工厂测试,结果表明该系统满足设计要求,可用于盾构刀盘工作状态监测。During the shield tunnelling,the cutterhead is in a black box state because the chamber behind the cut⁃terhead is pressurized.In order to monitor the working state of the disk cutters and cutterhead in real time,a realtime monitoring system of cutterhead conditions in shield tunnelling is developed.The system consists of three sub⁃systems,namely the sensor subsystem,control and data transmission subsystem,algorithm and display subsystem.The sensor subsystem integrates the self-made disk cutter wear sensor,disk cutter rotation speed sensor,tempera⁃ture sensor,data acquisition module and power supply unit.The integrated sensors are mounted in the disk cutter housings on the cutterhead to monitor the disc cutter wear and rotation speed and cutterhead temperature in real time.The collected data is transmitted to the central end through wire or wireless modes,and then transmitted to the upper computer by wire.The software of the upper computer integrates the shield design parameters,stratum param⁃eters,shield driving parameters and sensor monitoring parameters,by which it can display the parameters monitored by these sensors in real time,comprehensively determine the working condition of the cutterhead and predict the ser⁃vice life of the disc cutters.Through laboratory testing and factory testing,this system is proven to meet the design requirements and can be used for monitoring the working state of shield cutterhead.
