摘要: [目的] 针对降雨型滑坡预警中多源数据融合不足的问题,本文以福建省龙岩市为例,构建了融合三维监测与多模型分析的滑坡预警系统。[方法] 基于1984—2012年635起滑坡及同期降雨数据,确定EI-D降雨阈值曲线,验证准确率为93%;采用FR-SVM建立区域易发性评价模型,AUC值为0.85;利用无人机与六相机阵列实现边坡三维重建与形变监测;FLAC3D流-固耦合模拟表明,台风暴雨5 d内安全系数由1.676降至1.230,暴雨历时是重要变量。[结果] 该预警系统实现了区域易发性评估与单体变形监测的多层次协同。[结论] 本文可为同类地区滑坡防控提供技术参考。

Abstract: [Purposes] To address the insufficient integration of multi-source data in rainfall-induced landslide early warning,this study developed an early warning system integrating 3D monitoring and multi-model analysis with Longyan city,Fujian province as the study area. [Methods] Based on 635 landslide events and corresponding rainfall data from 1984 to 2012,an EI-D rainfall threshold curve was established with a validation accuracy of 93%.A regional landslide susceptibility model was constructed using the FR-SVM method,yielding an AUC of 0.85.UAV photogrammetry and a six-camera array were employed for 3D slope reconstruction and deformation monitoring.FLAC3D fluid-mechanical coupling simulation revealed that the factor of safety decreased from 1.676 to 1.230 within five days of typhoon-induced rainfall,indicating that rainfall duration is a critical variable for slope instability. [Findings] The integrated early warning system achieves multi-level synergy from regional susceptibility assessment to individual slope deformation monitoring. [Conclusions] This paper provides technical reference for landslide prevention and control in similar rainfall-prone areas.
