摘　　要：浆锚搭接连接主要用于装配式混凝土结构纵筋的连接。为研究浆锚连接节点可能出现的主要缺陷种类及形成机理,进行多次实地考察和模拟试验分析。试验结果表明,浆锚搭接连接的缺陷形成的主要原因有漏浆、二次灌浆、浆锚孔堵塞、钢筋及预留孔洞偏移、施工扰动、浆锚料流动性降低及其他施工不规范等。Grout-filled lap joint is mainly used to connect the longitudinal reinforcement of prefabricated concrete structure. In order to study the common defect types that the grout-filled lap joint can form, several field investigation and simulation test analysis are carried out. The experimental results show that the main reasons for the defect formation of the grout-filled lap joint are leakage, secondary grouting, grouting hole plugging, reinforcement and hole deviation, construction disturbance, the reduction of fluidity of grouting material and other construction irregularities.
