Therefore, the occurrence time of most landslides corresponds to the rainy season, especially the frequency of heavy rainstorms and heavy rainstorms. Short-term continuous rainstorms will lead to the emergence of disaster groups.

Embodiment Construction

[0029] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0030] The landslide prediction method of a specific embodiment provided by the invention comprises the following steps:

[0031] Step 1: Draw a contour map of the mountain body, and divide the mountain body into different altitude levels according to the contour lines: the data (coordinates, measured elevation) of the field measured points are collected by special instruments to generate point-type data files. Import the data file through the contour line automatic drawing program developed by VBA to generate Delaunay triangulation. Search for the first equivalent point, use interpolation method to calculate the coordinates of the equivalent point on the edge ...

Abstract

The invention relates to a mountain landslide prediction method, which comprises the following steps: drawing a mountain contour map; measuring the soil thickness of the mountain, and drawing a mountain bedrock contour map; according to the mountain contour map and the mountain bedrock contour map, predicting a mountain landslide place, wherein the bedrock gradient at the place changes between 25.0 and 45.0 degrees, and the soil thickness is over 15cm; measuring the infiltration rate of the soil on the predicted mountain landslide place; and predicting the mountain landslide time. According to the invention, based on the relation of the mountain soil changing with time, the mountain landslide place is predicted by taking the mountain contour map, the mountain bedrock contour map, the gradient and the soil thickness as evaluation factors, and the landslide position can be accurately predicted. According to the parameters such as soil infiltration rate, soil bulk density and soil water content, formula calculation is performed to predict the mountain landslide time, thus the mountain landslide time can be predicted relatively accurately.

Description

technical field [0001] The invention relates to a geological disaster prediction technology, in particular to a mountain landslide prediction method. Background technique [0002] Landslide is a kind of natural geographical disaster which is common all over the world and produces serious damage. Landslides mainly refer to the soil or rock mass of mountain slopes, under the influence of factors such as river erosion, groundwater activities, earthquakes and human destruction, under the action of gravity, along the weak surface or weak zone, integral or scattered along the slope The natural phenomenon of face down sliding. my country is one of the countries with the most serious landslide disasters in the world. 70% of the country has complex geological conditions and landslides are widely distributed. At present, the areas threatened by landslide disasters have accounted for 1 / 5 to 1 / 4 of the country's land area. It is very important to scientifically and timely and accurate...
