Early warning system and early warning method for railway landslide hazard

Abstract

Aiming at the worldwide problem for the early warning of the railway landslide hazard, in combination with the railway safe running and maintaining requirement, and synthetically using the geology, atmosphere, hydrology and electronic information technologies, the invention provides a three-level early warning method which decomposes the complex problem of the early warning of the railway landslide hazard into three levels of simple problems which are independent from one another such as tendency forecast, slip velocity forecast and accurate alarm and synthetically early warns by the monitoring of a rain gauge, a pull rope displacement sensor and a pressure sensor, wherein the method early warns (or monitors) the three levels such as the whole tendency of the happening of the landslide, the previous status which threats a line, and the precise moment which endangers the railway after the happening of the landslide, so that the three-level five-grade early warning solution which is suitable for the railway can be designed and realized, the exact, effective and practical early warning monitoring system for the railway landslide hazard can be formed, and various suggestions can be provided aiming at the using mode of the railway; and therefore, the invention is suitable for the landslide dangerous point sections along the railway, and the aim of effective early warning and monitoring of the railway landslide hazard can be achieved.

Description

technical field [0001] The invention relates to an early warning system for landslide disasters suitable for railways, including a three-layer and five-level early warning system for railway landslides and an application mode for railways. Background technique [0002] Landslide disaster is a disaster event in which the slope soil or rock mass loses its original stable state under the action of gravity and slides down along the sliding surface (or sliding zone) inside the slope, causing casualties and property losses. It has the characteristics of concealment, suddenness and destructiveness. The occurrence of landslide disasters is caused by the change of natural environment, and also by the frequent and unreasonable engineering activities of human beings. [0003] There are many monitoring and forecasting schemes or methods for landslide disasters, some of which are already very mature, and some are still in the stage of research and experimentation. [0004] The followin...

Problems solved by technology

[0009] Aiming at the worldwide problem of early warning of railway landslide disasters, the present invention proposes to decompose the complex problem of early warning of railway landslide disasters into trend forecast, imminent slip forecast, Precise alarm is a simple problem with three independent levels, which is a three-level alarm method for comprehensive early warning after solving them separately. This method is carried out from three levels: the overall trend of landslide occurrence, the state before the threat to the line, and the precise moment when the landslide endangers the railway. Early warning (or monitoring), designed and implemented a three-layer and five-level alarm solution suitable for railway applications, formed an accurate, effective and practical early warning and monitoring system for railway landslide disasters, and put forward various suggestions for railway operation modes to apply At the dangerous point of landslides along the railway, it can achieve the purpose of effective early warning and monitoring of railway landslide disasters
