摘　　要：目前,传统路缘石大多为矩形截面长方体结构,材质主要为大理石或素混凝土,存在稳定性差、结构强度低的缺陷。本文在分析传统路缘石缺陷的基础上,对榫卯结构钢筋混凝土复合路缘石的外部结构和内部材料组成进行了研究,研究结果表明,L形截面和榫卯结构大大增强了复合路缘石的水平和竖向稳定性,钢筋混凝土结构大幅提高了复合路缘石的强度。At present,most of the traditional curbs are rectangular section cuboid structures,mainly made of marble or plain concrete,which have the defects of poor stability and low structural strength.On the basis of analyzing the defects of traditional curb,the external structure and internal material composition of reinforced concrete composite curb for mortise and tenon joints are studied.The results show that L-shaped section and mortise tenon structure greatly enhance the horizontal and vertical stability of the composite curb,and reinforced concrete structure greatly improves the strength of the composite curb.
