摘　　要：依据北京山区公路沿线的地质灾害特征,提出基于物联网技术的北京地区公路高边坡地质灾害监测系统的框架,该系统由数据采集子系统、数据管理子系统、崩塌监测预警子系统及信息服务与共享子系统组成,采用C/S模式和B/S模式的双模式运行。根据多年北京突发地质灾害应急调查情况,选取密云区硫辛路崩塌多发路段进行研究与应用,监测系统可实现位移变形、倾斜度、落石报警、降雨量等野外数据采集,室内数据管理分析、监测预警、信息服务与共享等功能。根据硫辛路崩塌灾害应急调查资料与国内典型崩塌监测预警经验确定研究区单因子判据及综合判据,包括临界雨量、裂缝变形量、裂缝变形速率、倾斜度变化量以及崩塌发育过程中的宏观异常现象,为北京市地质灾害防灾减灾决策,提供一定的技术支撑。Based on the analysis of the characteristics of geological hazard along Beijing highway,this paper puts forward the framework of geological disaster monitoring system for high slope along Beijing highway based on Internet of things technology,which is composed of data acquisition subsystem,data management subsystem,collapse monitoring and early warning subsystem and information service and sharing subsystem.The system is operated in hybrid mode of C/S mode and B/S mode.According to the emergency investigation of sudden geological disasters in Beijing for many years,the Liuxin Road in Miyun is selected to conduct the demonstration research and application.The monitoring system can realize the functions of displacement and deformation,inclination,rockfall alarm,rainfall and other field data collection,indoor data management and analysis,monitoring and early warning,information service and sharing.According to the emergency investigation data of Liuxin Road collapse disaster and the experience of typical collapse monitoring and warning in China,the single factor criterion and comprehensive criterion of the demonstration area are determined,including critical rainfall,fracture deformation amount,fracture deformation rate,gradient variation and macroscopic abnormal phenomena in the process of collapse development.It provides certain technical support for disaster prevention and reduction decision-making of geological disaster in Beijing.
