基于AHP-灰色关联分析方法的嘉峪关墩台遗址病害评价
首发时间:2020-03-23
摘要:嘉峪关长城是万里长城的最西端,是现存明长城防御体系中规模最大的关隘,墩台是长城防御体系的重要组成,嘉峪关明长城墩台广泛分布在嘉峪关境内,保护工作亟待开展。本文通过历史文献的查阅和相关资料的收集整理,对研究区地理地貌特征和病害发育情况进行了系统调研,通过AHP-灰色关联分析方法对嘉峪关地区墩台遗址的危险性进行了评价,认为该地区墩台遗址的病害危险性排序为坍塌病害最危险,掏蚀病害其次,裂隙病害和冲沟病害因墩台遗址而异,并最终建立了危险性评价体系,在日后关于类似单体土遗址的保护工作中能起到积极的借鉴作用。

Deterioration Assessment of Pier Sites in Jiayuguan Based on AHP and GRA
Abstract:Jiayuguan Great Wall is the westernmost end of the great wall and the largest pass in the existing defense system of the great wall of Ming Dynasty. Piers and abutments are an important part of the defense system of the Great Wall. The piers and abutments of Jiayuguan Great Wall of Ming Dynasty are widely distributed in Jiayuguan, and the protection work needs to be carried out urgently. In this paper, through the review of historical documents and the collection and arrangement of relevant data, the geographical and geomorphic characteristics and disease development of the study area were systematically investigated, and the risk of the pier and abutment sites in Jiayuguan area was evaluated by AHP-grey correlation analysis method. It was considered that the risk of the pier and abutment sites in this area was ranked as the most dangerous collapse disease, followed by the excavation disease, fracture disease and The gully disease varies with the pier and abutment sites, and finally a risk assessment system is established, which can play a positive role in the protection of similar single earth sites in the future.
