Application of Extension Method for Risk Assessment on Geological Disaster in Pipeline Project of Natural Gas Transmission
摘要
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.关键词
