Other Abstract"5·12"汶川地震灾区的泥石流灾害具有规模超大、群发性等特点。针对这些特点,监测预警将是及时有效而经济合理的防灾手段之一。在分析国内外泥石流预警研究进展的基础上,针对目前地震次生泥石流监测预警实践中的一系列问题,提出了一种基于泥石流形成运动过程的泥石流监测预警体系。该体系从泥石流形成机理研究出发,监测泥石流形成运动各阶段的特征参数,并根据各参数预警阈值建立相应的临灾预警等级,形成了全流域的泥石流综合监测预警体系,适用于汶川地震灾区这种高频率、大规模泥石流的防灾减灾工作; According to the massive total volume, group-occurring of debris flows in Wenchuan Earthquake stricken area, the monitoring and warning system will be an economic and effective process. Based on analysis of past performance of debris flow warning and existing problems, this paper proposed a new debris flow hazard monitoring and warning system based on the initiation and motion mechanism of debris flow. The new system were consisted by rainfall monitoring, fluid level monitoring, pore-water pressure monitoring, soil moisture monitoring, ground vibration monitoring and video monitoring. And the warning rank were established after the comprehensive analysis of threshold value of all these detectors. It would be suitable to use this comprehensive monitoring and warning system for protecting debris flow threatened areas in Wenchuan Earthquake stricken area.
