摘　　要：地表位移是边坡变形监测中的重要特征量,而常规的地表位移监测仪器难以有效融入远程自动监测系统中。利用新型触发式位移计对公路边坡地表位移进行监测,位移计与接收器之间可以利用无线传感网进行短距离无线组网,接收器连接采集传输系统通过GPRS网络将监测数据远程实时传送到远程监控中心,形成了节能、高效、无线、实时的地表位移远程监测系统。该位移计精度可达到1 mm,通过室内标定和现场变形对比观测分析,验证了该设备的精度。通过在某高速公路边坡的安装运行,位移计成功地进行远程监测预警,根据实时的位移监测结果,为高速公路的防灾减灾提供了参考依据。Surface displacement is an important character in slope deformation monitoring, but conventional monitoring instrument is difficult to be incorporated into remote automatic monitoring system. New trigger displacement meter was used to monitor the surface displacement of highway slope, wherein the meter and the receiver was in short-distance wireless networking by wireless sensor network, and the receiver connected to capture and transmit system can transfer the real-time monitoring data to remote surveillance center by GPRS network, thus a remote real-time monitoring system, which is of energy conservation, high efficiency and wireless, was established. The accuracy of the displacement meter may reach 1 mm, which is validated by comparative analysis of laboratory calibration and on-site deformation observation. The displacement meter has been installed along a highway slope and put into service, and made remote monitoring and early warning successfully. The real-time monitoring result offers reference to highway geohazard prevention and reduction.
