Problems solved by technology

According to the real-time soil moisture content and the rainfall counted in different time periods in the past, it can reflect the current slope conditions. However, in the rainy season in some areas in the south, it often rains continuously for many days. The

Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] Such as Figure 1-3 As shown, the present invention selects slope relative height, slope gradient, vegetation coverage, soil texture, soil water content, stratum lithology, erosion intensity, slope loose matter storage, disaster occurrence sensitive zone, previous 3d cumulative rainfall, The 24-hour rainfall and 10-minute rainfall are the impact indicators (that is, impact factors) of the soil erosion early warning model. Among them, the slope loose matter storage is an important source of water and soil erosion sources. The larger the storage, the more solid debris can be provided when water and soil loss occurs: the looser the solid debris, the easier it is to lose stability and damage under rainfall conditions. Therefore, the soil erosion ditch has a certain amount of loose matter, which provides source conditions for the formation of water and soil erosio...

Abstract

The invention develops and establishes a water and soil loss monitoring and early warning system with a forecast function. A water and soil loss early warning model is established on the basis of an efficiency coefficient method, various variates can be considered to integrally forecast a water and soil loss ditch, water content of soil and rainfall can be set into the value of a next time t1, the situation of water and soil loss can be forecasted ahead of time, dangers can be forecasted ahead of time, a user has enough response time to handle the dangers, and particularly, debris flow risks caused by water and soil loss can be avoided and relieved when in continuous heavy rain weather.

Description

technical field [0001] The invention relates to the environmental safety assessment and early warning along the railway, in particular to the monitoring and early warning of water and soil loss along the railway. Background technique [0002] The railway is the main artery of the national economy and plays an important role in transportation, but soil erosion seriously affects the normal operation and driving safety of the railway. my country is one of the countries with frequent soil erosion activities, and the railway is one of the most serious industries suffering from soil erosion. Soil erosion often causes erosion, silting, and blockage of bridges and culverts on railway subgrades, seriously affecting the safe operation of railways. With the deterioration of the global environment in recent years, extreme weather occurs frequently, and railways continue to extend to mountainous areas. Water and soil erosion disasters along the railways occur frequently, which seriously...
