Abstract

The invention discloses a landslide hazard monitoring system and method. The system comprises a data monitoring equipment module. The data monitoring equipment module is connected with a data transmission module; the data transmission module is connected with a data reception module; and the data transmission module and the data monitoring equipment module are connected with a power supply module for supplying power therefor. The data monitoring equipment module comprises a rainfall monitor for monitoring rainfall, a volumetric water content monitor for monitoring landslide soil body volumetric water content, and a GPS device for monitoring landslide surface displacement. The landslide hazard monitoring system and method can judge possible spatial form and development tendency of a side slope, capture feature information of slope disaster in time and predict slope instability damage time and range in time by monitoring the landslide surface displacement, the rainfall intensity and the soil body volumetric water content in real time, and summarizing response of the soil body volumetric water content to the rainfall and deformation features of the side slope.

Description

technical field

[0001] The invention relates to the field of slope disaster monitoring, in particular to a landslide disaster monitoring system and method. Background technique

[0002] my country's loess area is about 630,000 km 2 , accounting for about 6.6% of the country's land area, and loess landslides are the most common geological disasters in loess, with hundreds of landslides occurring every year. Statistics show that there have been 1,131 loess landslides in Shaanxi Province and more than 1,300 in Lanzhou. , 4,576 places in eastern Gansu Province, due to the special structure of loess and its sensitivity to water, how to reduce the losses caused by it has become a national problem. With the development of economy, the number of large-scale projects in the west has increased, and loess landslides The monitoring and early warning has attracted the attention of government departments and relevant scientific researchers, and its monitoring and early warning work is in...
