泥石流危险度测试模型与多传感器监测系统

为较准确地预测泥石流的发生,达到防灾减灾的目的,建立一种将多种传感器感知的动态监测信息与地质环境信息相结合的泥石流危险度预测模型。根据泥石流的形成条件和演化机理,量化研究发生泥石流的临界降雨强度、临界倾斜角和临界泥砂堆积层高度。基于该模型,设计并制作由雨量、倾斜、物位3种传感器组成的多传感器监控系统。分析和试验结果表明:该模型和监控系统具有预测泥石流危险度的功能,摄取的信息较全面,准确性更高,时效性更强,置信度较高。

Hazard Test Model for Debris Flows and Multi-sensor Monitoring System

To accurately predict the occurrence of debris flow,and thus prevent and weaken the disaster,this paper built a hazard test model for debris flows which combines dynamic monitoring signals perceived by multi-sensor with geological environment information.According to the formation conditions and the evolution mechanism of debris flows,the critical rainfall intensity,critical tilt angle and critical accumulation horizon of sand and mud during debris flow were quantitatively studied.Based on the model,a multi...
