Embodiment Construction

[0100] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0101] Such as figure 1 As shown, a method for intelligent early warning and forecasting of soil slope hazards includes the following steps:

[0102] S1, set up a rainfall monitoring station with automatic data conversion function on site, and embed soil infiltration meters and displacement meters with automatic data conversion function;

[0103] S2, the rain gauge and the sensor respectively collect the real-time working conditions of the slope rainfall and the deformation and displacement data of the slope to the data collection station through the optical fiber cable, and the data...

Abstract

The invention relates to an intelligent early warning and prediction method for a soil slope danger. The method comprises the following steps: 1) a rainfall monitoring station is set in an onsite mode, and a soil penetration meter and a displacement meter are buried; 2) a rainfall condition, soil permeability and displacement data of the slope are acquired in real time and transmitted to a remote client; 3) the data are formatted and processed; 4) the weight size of data such as the rainfall condition, the soil permeability and the slope displacement influencing a slope safety factor is calculated; 5) a safety factor for each time period of the slope is determined; 6) the rainfall condition at each time period, the slope soil permeability factor and a relation among deformation, displacement and the safety factor are calculated, and a soil slope destruction happening time is predicted; 7) hidden destructed slope critical destruction and instability time are acquired, and disaster happening time is predicted; and 8) in combination with results from the sixth step and the seventh step, early warning and prediction are carried out on a slope danger. Compared with the prior art, the method can be used for carrying out soil slope danger early warning and prediction more reasonably, more quantitatively and more practically.

Description

technical field [0001] The invention relates to the technical field of disaster early warning and forecasting for soil slope engineering, in particular to an intelligent early warning and forecast method for soil slope dangers. Background technique [0002] China is one of the countries with the worst landslides in the world. Only in the six years from 2006 to 2011, there were 157,927 landslides in the whole country. In recent years, China's annual economic losses caused by landslide disasters are more than 1 billion US dollars. In 2009, there were only 16 super-large and large-scale landslide disasters across the country, with direct economic losses reaching 190 million yuan; in 2011, there were 7 major landslide disasters with more than 10 people dead, missing, or direct economic losses of more than 100 million yuan, with direct economic losses of more than 100 million yuan. Loss of 599 million yuan. Landslide disasters not only cause huge economic losses, but also seri...
