摘　　要：青银高速公路铜冶互通投入运营后,部分匝道出现路面裂缝、路基不均匀沉降、挡土墙面板变形等病害。2022年8月,受强降雨影响挡土墙面板坍塌10 m。分析了铜冶互通加筋土挡土墙路段病害产生的原因,提出了锚杆框架梁、边坡填土等加固方案。从施工可行性、工期和造价等因素综合考虑确定了加固方案,并从滑动稳定性和倾覆稳定性等方面进行了验算。After the operation of Tongye Interchange of Qingyin Expressway,there are diseases such as pavement cracks,uneven settlement of subgrade,and deformation of retaining wall in several ramps.Affected by the heavy rainfall in August 2022,the retaining wall panel collapsed by 10 m.This paper analyzed the disease causes of the reinforced soil retaining wall section in Tongye Interchange and proposed the reinforcement schemes of anchor frame beam and slope filling.The reinforcement scheme was determined in comprehensive considerations of construction feasibility,construction period,and cost,and its sliding and overturning stability were checked.
