Embodiment 1

[0113]

[0117] When the superentropy is by (-0.0979,-0.151], the negative superentropy increase rate slows down, but can reach the extreme value-0.151, this

[0118] When the superentropy is [0, 38.85), although the debris flow is degraded, it still has the conditions for the outbreak of a medium-scale debris flow,

[0119] When the superentropy is [38.85, ∞), the debris flow declines, but sporadic debris flows can still erupt, and there is still a small scale for eruption.

Abstract

The invention discloses a method for predicting debris flow activity in a strong earthquake area based on the accumulation of material sources, which includes the following steps: S1: through large-scale surveying and mapping, collect the longitudinal sections of 20 debris flow ditches, and calculate the longitudinal sections of each ditch according to the elevation Carry out equal divisions, measure the ditch length l and the height difference h of each ditch segment; S2: measure the total ditch length L of the main channel of the debris flow and the maximum relative height difference of the debris flow channel H; S3: Obtain the total provenance P in the debris flow basin and the drainage area A of the debris flow ditch through remote sensing interpretation and field investigation; solve the problem that the calculation results of the previous methods are not accurate enough to strengthen the prevention and control measures for highly active debris flow ditch The problem.

Description

A Debris Flow Activity Prediction Method in Strong Earthquake Regions Based on Provenance Aggregation technical field The present invention relates to the field of debris flow prevention and control engineering, particularly a kind of debris flow activity in the strong earthquake area based on the accumulation of provenance. Mobility forecasting method. Background technique Debris flow is a kind of common geological disaster in mountainous area, and its outbreak is sudden, lasts short, and destructive force is strong, and harm involves Transportation, hydropower, land and other fields. Seismic activity changes natural conditions such as the topography of mountainous areas and causes mountains in earthquake areas The slope has been in an unstable state for a long time, resulting in a large number of loose sources, which provides a more favorable condition for the occurrence of debris flow. pieces. Therefore, the debris flow in the earthquake area will remain highly ...
