摘要
为解决川西峡谷山区公路韧性评估难题,以排序法和专家调查分析法为基础,结合四川省西部山区公路特点,从公路韧性的抵抗力、恢复力和路网冗余度出发,建立山区公路韧性评估指标体系,提出山区公路韧性评估方法,并对映秀至汶川通道进行实例验证.结果表明,2013-2023 年的公路建设对映秀至汶川通道整体韧性的提高作用显著.
Abstract
In order to solve the problem of highway resilience evaluation in western Sichuan canyon mountainous area,based on the sorting method and expert investigation and analysis method,combined with the characteristics of mountainous highways in western Sichuan Province,starting from the resistance,resilience and road network redundancy of highway resilience,the resilience evaluation index system of mountainous highway is established,the resilience evaluation method of mountainous highway is proposed,and the Yingxiu to Wenchuan channel is verified by an example.The result show that the overall resilience of Yingxiu to Wenchuan channel has been improved obviously by the highway construction from 2013 to 2023.
