摘　　要：城市防洪堤挡墙肩负着防洪安全重任。以清新区一级截洪渠挡墙除险加固治理工程为例,针对其挡墙部分砌石砂浆饱满度不足,两岸未设置护脚,墙脚处勾缝砂浆被掏空等问题突出,对堤防挡墙进行结构和渗流安全稳定复核,现状浆砌石挡墙抗滑移、抗倾覆验算不满足规范要求。提出了右岸新建挡墙形式采用C25钢筋混凝土重力式挡土墙,左岸新建C30钢筋混凝土悬臂式挡墙压顶,实现了区内防洪堤挡墙的安全长期稳定运行。Urban flood control embankments and retaining walls shoulder the heavy responsibility of flood control safety.Taking the reinforcement and treatment project of the first level flood interception channel retaining wall in Qingxin District as an example,the insufficient fullness of the masonry mortar in the retaining wall,the lack of foot protection on both sides,and the hollowing out of the joint mortar at the foot of the wall are prominent problems.This article conducts a structural and seepage safety and stability review of the embankment retaining wall,and finds that the current mortar masonry retaining wall's anti slip and anti overturning calculations do not meet the regulatory requirements.Therefore,it is proposed to build a new retaining wall on the right bank using C25 reinforced concrete gravity retaining wall,and a new C30 reinforced concrete cantilever retaining wall on the left bank to press the top,achieving safe and long-term stable operation of the flood control embankment retaining wall in the area.
