崩塌地质灾害受到地形条件约束,一般在峡谷地带尤其发育.地形陡峻、沟谷深切,加之强烈的风化作用影响,导致运营公路在峡谷路段安全风险剧增.该文通过文献调研简述了崩塌地质灾害的成因类型,总结为倾倒式、滑移式、错断式、拉裂式和鼓胀式五类;危岩落石的运动特征复杂,受地形条件控制表现出崩落、跳跃、滚动、抛散等形式.该文分析了高位危岩对公路设施的危害及其特点,论述了当前崩塌危岩体监测的主要技术手段及其优越点.基于该领域的研究现状,初步提出了适用于运营公路高位危岩的监测思路:无人机贴近倾斜摄影测量快速识别→危岩体与监测区段划分→视频/激光雷达图像识别监测→监测预警与应急处置.该文提出的监测思路旨在崩塌发生后迅速预警,可有效应对次生灾害的发生,减少灾害造成的进一步损失,赢得抢通救灾的宝贵时间,对山区公路类似情况具有一定的参考价值.
An briefanalysis of the current status of monitoring technology for high-level collapse hazardous rock bodies on operational highways
Avalanche geological hazards are constrained by topographic conditions and are generally particularly developed in canyon areas.The steep topography and deep ravines,together with the effects of strong weathering,lead to a dramatic increase in the safety risks of operating roads in the ravine sections.The paper briefly describes the types of causes of avalanche geological hazards through literature research,which are summarized into five categories:tipping,sliding,faulting,pulling and bulging;The movement characteristics of dangerous rockfalls are complex,controlled by topographic conditions showing forms such as crashing,jumping,rolling and throwing.The paper analyses the hazards of high-level dangerous rocks to highway facilities and their characteristics,and discusses the current main technical means of monitoring the crumbling dangerous rock bodies and their superior points.Based on the current state of research in this field,preliminary ideas on monitoring of high-level hazardous rocks applicable to operating highways are proposed:Rapid identification by UAV close tilt photogrammetry → Dangerous rock body and monitoring section delineation→Video/LIDAR image identification and monitoring→Monitoring,early warning and e-mergency response.The monitoring idea proposed in this paper is aimed at rapid early warning after the occurrence of collapse,which can effectively deal with the occurrence of secondary disasters,reduce further losses caused by the disaster,and win valua-ble time for rescue and relief,and it has certain reference value for the similar situation of the mountain highway.
