摘要
针对山区公路沿线滑坡灾害时空演化复杂、诱发机制多样及传统处治手段响应滞后的问题,提出一套识别-预警-控制全流程一体化的滑坡处治方法。在隐患识别方面,融合遥感影像、InSAR干涉测量、无人机航测及激光雷达等多源数据,提出滑坡快速识别与演化追踪方法,并结合地球物理勘探与钻孔测斜,精准解析滑动面几何特征。在监测预警方面,建立融合GNSS、测斜、应力计、微震及气象传感器的多参量监测体系,构建基于变形-力学控制-环境响应的分级预警模型,实现复杂地质条件下滑坡的动态监测与精准预警。在控制策略方面,提出集成微型桩和智能锚固等构件的结构优化与阶段化快速应急处治策略,实现针对性强、部署高效的处治目标。提出的方法在都巴高速那良滑坡治理工程中得到验证,结果表明其在公路沿线滑坡“识别-预警-控制”一体化处治中适应性较强。
To address the challenges of complex spatiotemporal evolution,diverse triggering mechanisms,and delayed responses of conventional treatments for highway-associated landslides,this study proposed an integrated full-process“identification-early warning-control”approach for landslide hazard management.In the hazard identification stage,a rapid landslide detection and evolution-tracking method was developed by integrating multi-source data including remote sensing imagery,Interferometric Synthetic Aperture Radar(InSAR)interferometry,Unmanned Aerial Vehicle(UAV)photogrammetry,and Light Detection and Ranging(LiDAR),combined with geophysical prospecting and borehole inclinometers to accurately delineate the geometric characteristics of sliding surfaces.In the monitoring and early warning stage,a multi-parameter monitoring system was established by integrating Global Navigation Satellite System(GNSS),inclinometers,stress meters,microseismic sensors,and meteorological instruments,and a hierarchical early warning model was constructed based on deformation-mechanical control-environmental responses,enabling dynamic monitoring and accurate early warning under complex geological conditions.In the control strategy stage,a phased rapid emergency treating strategy was proposed,integrating structural optimization with components such as micropiles and intelligent anchoring systems,to achieve highly targeted and efficiently deployable countermeasures.The proposed methodology was validated through its application to the Naliang landslide treatment project along the Duba Expressway.The results demonstrate its strong engineering adaptability and high potential for broader implementation in integrated“identification-early warning-control”treatment of landslides along highway.
