Reinforcement Scheme of Reinforced Soil Retaining Wall in Tongye Interchange of Qingyin Expressway
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.
