A highway landslide damage loss evaluation model and a construction method thereof

Abstract

The invention discloses a highway landslide damage loss evaluation model, comprising: a loss evaluation module, which is used for analyzing and calculating a highway landslide damage loss degree dataanalysis module; a data analysis module, which is used to analyze the data transmitted by the data acquisition module and make induction and statistics; a data acquisition module, which is used to collect the data of the past highway landslide accidents and provide the data source for the data analysis module; and a regional isolation analysis module, which is used to analyze the cause of highwaylandslide and the link between road landslides and losses from road landslides. At the same time, the invention also provides a method for constructing a highway landslide damage loss evaluation model, which can objectively, accurately and comprehensively evaluate the highway landslide damage loss by combining the big data analysis, the analytic hierarchy process and the influencing factor analysis method.

Description

technical field [0001] The invention relates to the field of road disaster evaluation, in particular to a road landslide damage loss evaluation model and a construction method thereof. Background technique [0002] Landslide refers to the soil or rock mass on the slope, affected by factors such as river scouring, groundwater activity, rainwater immersion, earthquake and artificial slope cutting, under the action of gravity, along a certain weak surface or weak zone, the whole or scattered The natural phenomenon of land sliding downhill. The moving rock (soil) body is called displacement body or sliding body, and the underlying rock (soil) body that has not moved is called sliding bed. [0003] Among the landslide accidents, road landslides have a larger impact range. Road landslides not only affect normal vehicles, but also may cause accidents to vehicles. Therefore, it is quite necessary to evaluate the losses caused by road landslides. In the prior art, the analytic hi...

Problems solved by technology

[0007] (1) In the prior art, the road landslide damage loss evaluation model is often constructed by a single AHP, which often has more qualitative colors, and the number of road landslide damage loss evaluation indicators is large, and there are many There are difficulties in judging the importance of the two indicators, so there are certain limitations in the evaluation of highway landslide damage and loss by using AHP alone;

[0008] (2) In the prior art, in the construction process of the road landslide damage loss evaluation model, the evaluation score of the evaluation index in the analytic hierarchy process is often determined by the expert scoring method, and the evaluation score of the evaluation index is determined by the expert scoring. Influenced by subjective factors, it cannot objectively and accurately reflect the loss of highway landslide damage, and there are certain defects;

[0009] (3) In the existing technology, when the AHP is used, it is necessary to qualitatively divide the importance of the evaluation indicators. In the process of dividing the importance, there is a certain degree of human subjectivity, which cannot accurately and objectively reflect the The loss of landslide damage, at the same time, when the evaluation index is determined artificially, a consistency test is required, and the weight value needs to be corrected according to the consistency test result, which greatly increases the amount of calculation of the weight value of the evaluation index
