Analysis of slope damage characteristics of operating expressway in Guangdong Province
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.
