Method of identifying slip factors causing slope instability by utilizing displacement monitoring

Abstract

The invention discloses a method of identifying slip factors causing slope instability by utilizing displacement monitoring. The method of identifying the slip factors causing the slope instability by utilizing the displacement monitoring includes the following steps: step one, the number of to-be-tested slopes, the number of samples of the slopes, and slope elements in a to-be-test area are determined; step two, slope displacement monitoring foundation pile points are arranged, displacement monitoring datum points are selected to form a slope displacement monitoring control net; step three, optical fiber monitoring displacement number equipment and equipment monitoring of the displacement monitoring datum points are arranged; step four, quantified slip factors and qualitative slip factors causing the slope instability are determined; step five, reference variable, namely slop displacement statistical magnitude is determined; step six, a prediction equation of relevancy of the slip factors causing the slope instability is set up; step seven, the prediction accuracy of the prediction equation of relevancy of the slip factors causing the slope instability is calculated; and step eight, the contribution and influence degrees of each slip factor to the slope instability are analyzed. The method of identifying the slip factors causing the slope instability by utilizing the displacement monitoring achieves the conversion from qualitative variable to quantitative variable, and resolves the problem of mutual conversion of multiple correlations among the factors.

Description

technical field

[0001] The invention relates to a method for identifying slip factors caused by slope instability, in particular to a method for identifying slip factors caused by slope instability using displacement monitoring. Background technique

[0002] Slope instability is a very harmful geological disaster and a common environmental geological phenomenon. Its formation conditions are complex and there are many slip factors. It is not only closely related to regional geological and background conditions, but also to external environmental factors and groundwater. It is closely related to sliding factors such as human activities, and its formation and occurrence are the result of the comprehensive action of the above-mentioned internal and external sliding factors. However, the above-mentioned slip factors have different effects on the slope and the magnitude and degree of their effects are different. The slip factors are not only numerous, but also complex in compositi...
