| Debris flow is a loose solid material under the action of hydrodynamic form of solid, liquid, gas three-phase hybrid material concentrated rapid flow and accumulation of a sudden strong dangerous geological disaster, nearly ten years had caused venezuela vargas region about 30000 people died (1999), the Philippine town of st. Bernard thousands of people have been killed more than 200 pupils (2006), zhouqu county of gansu province, 1765 people were missing (2010).Establish and improve the mud-rock flow disaster warning and mitigation system such as remote monitoring, has been the important means of non-engineering disaster mitigation measures such as at home and abroad.Taking ChengKun railway K349+462 of Qiao Le Mu gully multimode remote monitoring project, introduce advanced technology and equipment from Japan, The mud-rock flow disaster monitoring from the outbreak of mud-rock flow elements:water (rainfall, water level), loose solid material (formation scaling), flow detector (debris flow meter) for real-time monitoring, monitoring data through wireless spread to data management platform, through the analysis of the data management platform for intelligent, and warning information. Through the above research, each item of debris flow monitoring and organic combination of the set classification threshold monitoring information, realize the accuracy and timeliness of ascension. At the same time according to the characteristics of debris flow hazards in the mountain area along the railway, the multimode debris flow warning technology are analyzed and discussed, compatible with existing ChengKun railway rainfall early warning system, and further refinement of the process of debris flow monitoring and alert, to improve the practicability and reliability of monitoring and early warning, this system can be applied to the actual work of railway flood disaster prevention. |
