摘要:

从系统理论出发,利用可拓方法基本理论,在物元模型理论的基础上建立地质灾害危险性评价的物元模型,确定了影响地质灾害危险性评价的12个评价指标,并采用层次分析法计算物元模型中各评价指标的权系数。建立地质灾害危险性分级标准,并进行相应的量化赋值。通过西气东输二线工程龙岗—西峡支干线工程地质灾害危险性分段评价的实践应用研究,证明这一方法用于地质灾害危险性评价有效可行。

Abstract:

By applying matter-element theory and extension engineering method,the matter element model of risk assessment of geological disaster was established in this paper. Twelve indexes were selected to be evaluating factors of the synthesis appraising system. The stratification analysis method used to calculate twelve aggregation of evaluating factors was proposed. The risk grading standard of geological disaster was established, and the corresponding value assignment was done. The application on the risk assessment of Longgang-Xixia Branch Pipeline Project of the Second West-to-East Gas Pipeline Project proves that the extenics method is feasible in risk assessment of geological disaster.

Key words: geological disaster, risk assessment, evaluation index, extenics method, matter element model
