广东省营运高速公路边坡病害特征分析

Analysis of slope damage characteristics of operating expressway in Guangdong Province

营运高速公路边坡养护长期缺乏规范指导,随着边坡本身地质环境的不断劣化、防护措施老化及极端天气增加,部分路段时常发生滑坡、泥石流或落石等突发性地质灾害,造成极大的社会影响。本研究以近40条营运高速公路近年来的边坡历史病害为研究对象,统计广东省营运高速公路边坡病害类型,结合灾害易发性、危险性,对营运高速公路边坡病害特征进行统计分析,得到了营运高速公路边坡病害特征规律,研究成果可为广东省营运高速公路边坡的维养提供有利的参考和指导。

There has been a lack of normative guidance for the maintenance of expressway slope in Guangdong Province for a long time.With the continuous deterioration of geological environment of the slope itself,the aging of protective measures and the increase of extreme weather,sudden geological disasters such as landslides,debris flows,or rockfalls frequently occur in some sections,and cause great social impact.Taking the slope historical diseases of approximately 40 operating expressways in recent years as the research object,the disease types of operating expressways slope in Guangdong province were categorized in this study.Combined with the vulnerability and risk of disasters,the slope disease characteristics of operating expressways were statistically analyzed,and the slope disease characteristic patterns of operating expressways were obtained.The research results can provide favorable reference and guidance for the maintenance of expressway slope in Guangdong Province.
