Embodiment

[0055] Such as figure 1 Shown is the basic flowchart of a kind of fuzzy variable weight engineering geological environment quality evaluation method of the present invention, and this method comprises the following steps:

[0056] Step 1: Establish a hierarchical structure model for engineering geological environmental quality evaluation, including a total target layer, a sub-target layer and an evaluation index layer. The total target layer is the general target of the engineering geological environmental quality evaluation, and the sub-target layer It is multiple sub-goals corresponding to the overall goal, each sub-goal includes multiple participating indicators, and all participating indicators form the evaluation index layer;

[0057] Step 2: Obtain the engineering geological data corresponding to all evaluation indicators in the hierarchical structure model of engineering geological environmental quality evaluation in the area to be evaluated;

[0058] Step 3: Import th...

Abstract

The invention relates to a fuzzy variable-weight engineering geological environment quality evaluation method comprising the following steps: establishing an engineering geological environment quality evaluation hierarchical structure model; acquiring engineering geological data corresponding to all participating indexes in an area to be evaluated; dividing the area to be evaluated into m basic evaluation units; establishing the evaluation index matrix and the variable weight matrix of each basic evaluation unit; calculating the variable-weight comprehensive evaluation value of each basic evaluation unit according to the evaluation index matrix and the variable weight matrix corresponding to the basic evaluation unit; getting the engineering geological environment quality grade of each basic evaluation unit according to the variable-weight comprehensive evaluation value of the basic evaluation unit; and clustering the basic evaluation units of the same engineering geological environment quality grade through use of a clustering method to get an engineering geological environment quality comprehensive evaluation partition map. The method has the advantages of high evaluation precision, objective and reliable evaluation result, and the like.

Description

technical field [0001] The invention relates to an engineering geological environment quality evaluation method, in particular to a fuzzy variable weight engineering geological environment quality evaluation method. Background technique [0002] A city is a geographical space where human habitation and economic activities are highly concentrated, and it is also the most important field of engineering construction. The quality evaluation of engineering geological environment is an important task in the overall planning of the city.
