摘要:
川藏铁路沿线多经过艰险山区,地质结构复杂,泥石流灾害发生频繁,破坏力极强,如何对泥石流灾害进行防控,是建造川藏铁路急需解决的重大问题。基于山区铁路沿线泥石流的特点,分析了川藏铁路沿线泥石流的类型、成灾机理及运动过程,并据此建立泥石流预警系统。泥石流预警系统包括数据采集系统、数据传输系统、数据中心及预警系统,以降雨量、源地土体降雨入渗深度、泥石流运动过程阶段次声波以及沟道泥位作为预警的关键参数,并计算4个参数的临界值。预警过程中,由数据采集系统采集现场信息,通过数据传输系统将这些数据传送到中心计算机,与4个参数的阈值比较,从而发出预警级别。最后,对此预警系统进行仿真,判断此方法的可行性。
Abstract:
Along the Sichuan-Tibet Railway,there are many difficult and dangerous mountainous areas and the geological structure is complex. Debris flow disasters occur frequently,and the destructive power is extremely strong. How to prevent and control debris flow disasters is a major problem that needs to be solved urgently for the construction of the Sichuan-Tibet Railway. Based on the characteristics of the debris flow along the mountain railway,the types,disaster mechanism and motion process of debris flows along the Sichuan-Tibet railway are analyzed,and an early warning system for debris flows is established. The early warning system of the debris flow includes data acquisition system,data transmission system,data center and early warning system. The key parameters of the early warning are the rainfall,the depth of soil infiltration,the infrasound wave during the debris flow and the channel mud position. And the critical value of four parameters is calculated. During the early warning process,the data acquisition system collects on-site information and transmits these data to the central computer through the data transmission system. Compared with the threshold of the four parameters,an early warning level is issued. Finally,the early warning system is simulated,determining the feasibility of this method.
