Multi-level regional crustal stability evaluation method and system driven by multiple geoscience indexes

Abstract

The invention provides a multi-level regional crustal stability evaluation method and system driven by multiple geoscience indexes, and belongs to the field of crustal stability evaluation. The method comprises the steps that firstly, a basic evaluation unit is determined as an evaluation grid based on an evaluation platform, a three-layer regional crustal stability evaluation system composed of surface crustal stability, shallow crustal stability and deep crustal stability is constructed, and corresponding kernel characteristics are geological disaster susceptibility, engineering rock and soil characteristics and structural stability; evaluating the surface crustal stability, the shallow crustal stability and the deep crustal stability of each evaluation grid, processing the stability of each level to obtain a standardized score, and constructing surface, shallow and deep crustal stability row vectors; splicing the stability vectors of the three levels into a matrix, solving the trace of each matrix as a comprehensive regional crustal stability R score, and grading the crustal stability based on the R score. The accuracy and the application range of the evaluation result are improved.
