基于ANP和扩展TOPSIS法的青藏铁路冻土路基安全性分析
The safety analysis of the Qinghai-Tibet railway permafrost subgrade based on ANP and the extension of TOPSIS method
摘要
Abstract
For the purpose of legitimately and comprehensively determining the influencing factors and their weights, and objectively analyzing the security of the Qinghai-Tibet Railway permafrost subgrade, this paper established a safety analysis model of the Qinghai-Tibet Railway permafrost subgrade based on ANP and the extension of TOPSIS method. This model selected 7 typical monitoring sections, determined 17 main influencing factors, adopted the ANP model and analyze the weights of each influencing factors based on the Super Decision software. Then the grey correlation degree of each monitoring section is calculated based on the extended TOPSIS method and finally the safety classification of monitoring sections is given out. It has been proved that the analytical results are identical to the existing results and the safety of the 7 monitoring sections is highly consistent with the site conditions according to the comparison of the evaluation result and the actual situation. Consequently, it is very effective to use the proposed model to analyze the safety of subgrade.关键词
