Other Abstract

根据拟建川藏铁路线性工程的特征选取了道路状况、海拔高度、铁道类型等6个评价指标,采用贡献权重法对推荐设计方案进行了定量易损性评价。运用GIS系统中的自然断点法对易损性结果进行分级、制图及统计分析。结果表明:较高和高易损度区主要位于巴塘县(A1K640)到白玉县(AK746+924)之间的线路,并且处于较高和高易损度的车站多达57座(占75%)。建议在后期建设和维护时有针对性地加强环境监测,并修建相应的滑坡灾害防护设施以降低易损性,防止线路遭受滑坡灾害。

Based on the characteristics of the proposed linear Sichuan -T ibet railway engineering,the six evaluation indexes were selected in this paper, including road conditions,altitude,r ailway type,and so on. T he contribution weight method was applied to evaluate the quantitative vulnerability of the recommended design scheme. The vulnerability results were grading,mapping and statistical analysis by using the natural breaks method of GIS system. The results show that lines of the higher and high vulnerability area are between Batang county ( A1K640) and Baiyu county ( AK746 + 924) ,and the stations of the higher and high vulnerability degree are up to 57 ( 75%) seats. To prevent the landslide hazards of those railways,environmental monitoring should be strengthened and the corresponding protection measures should be taken to reduce the vulnerability of landslide hazards.
