摘要:泥位预警是泥石流灾害预警的方法之一,目前主要有接触式和非接触式泥石流泥位报警两

种方法。探讨了一种便于安装、适合山区铁路沿线泥石流监测预警的接触式泥位自动监测预警系统

的构建及应用方法。首先探讨了泥石流泥位监测系统的工作原理及其软件、硬件的组成,其次探讨

了泥位预警阈值确定方法,

最后根据现场试验观测情况及所遇到的问题提出了泥位监测系统的应用方法。该泥石流泥位监测预警系统能实现泥山区铁路沿线石流泥位信息数据采集和传输的网络化、

实时化、自动化、数字化(可视化),并根据监测信息及时向铁路相关部门发出预警信号。

Abstract :The early warning technology of mud-position is one of the debris flow early warning methods.At pres-ent ,there are mainly two kinds of early warning methods :contact type and non-contact type.This paper explores the method of construction and application of the mud —position monitoring and early warning system for mountainous area along railway line.The system is easy to install and suitable for the application of Mountainous debris flow dis-aster automatic monitoring and alarming.First ,the paper explores its working principle ,and the composition of soft-ware and hardware of the mud-position monitoring system of debris flow.Next ,it discusses the method to determine mud-position early warning threshold.At last ,according to the situation of field experiments and the problems that we met ,we proposed the application method of the mud-position monitoring system.The mud-position monitoring and early warning system for mountainous area along railway line can ensure the information collecting about the mud-position of debris flow ,the transmission and display should be networking ,real time ,automation and visualiza-tion.According to the information that they monitored ,they are able to send the early warning single to the relevant departments of the railway administration.

Key words :debris flow ;mud-position monitoring ;mud-position early warning threshold ;automatic monitoring and early warning system ;along railway line in mountainous area
