公路危岩及灾害具有点多面广,规模小,小变形,突发性和致灾性强等突出特点,其安全监测系统应具有低成本、耐久,高精度和高准确度等特点。基于此,提出了包括基于激光测距的非接触式危岩表面位移监测方法,危岩裂缝监测和宏观变形监测,以及基于射频识别技术(RFID)的危岩崩塌落石监测方法等系统的、适应公路交通需求的远程智能危岩安全监测方法。建立了公路崩塌落石灾害信息灾害声光报警装置,可将灾害信息及时告知过往车辆,避免次生事故发生。该监测与报警方法可为公路危岩加固处治决策和灾害预警提供技术支撑。
The highway rock and disaster have the characteristics of wide point, small scale, small deformation, suddenness and strong disaster. The safety monitoring system should have the characteristics of low cost, durability, high precision and high accuracy. Based on this, the methods of non-contact dangerous rock surface displacement monitoring based on laser range finding, the monitoring of dangerous rock cracks and macroscopic deformation, the monitoring methods of dangerous rock collapse and falling rock based on radio frequency identification (RFID) Remote Intelligent Dangerous Rocks Safety Monitoring Method for Highway Traffic Demand. A sound and light alarm device for informational disaster of landslide and rockfall disaster has been established, which can timely inform the passing vehicles of disaster information and avoid secondary accidents. The monitoring and alarming method can provide technical support for highway dangerous rock reinforcement treatment decision and disaster warning.
