摘要:为研究钢筋搭接长度、钢筋直径、套筒内部混凝土灌浆料强度等因素对钢筋连接效果的影响，对25个钢筋套筒注浆搭接试件进行单向拉伸试验，从试件破坏形态、试件强度、套筒应变、钢筋与套筒相对滑移量方面进行分析。由试验得出套筒长度及壁厚、钢筋直径、灌浆料强度及套筒端口处理等参数对钢筋套筒注浆搭接连接性能的影响规律，并根据试验数据和钢筋搭接连接机理分析，计算得到采用套筒注浆搭接时钢筋搭接长度计算公式，为其在装配式剪力墙中钢筋连接提供了一定的理论基础。

Abstract:In order to study the influence of the overlap length， bar diameter and strength of concrete grouting material inside sleeve on the connection effect of reinforcement， an one-way tensile test was carried out on 25 specimens of grouting overlap of reinforcement sleeve. The failure mode， strength， strain of sleeve and relative slip between reinforcement and sleeve were analyzed. The influence of sleeve length and wall thickness， reinforcement diameter， strength of grouting material and treatment of sleeve port on the performance of grouting overlap of reinforcement sleeve connection were obtained. Based on experimental data and analysis of the mechanism of reinforcement overlap connection， the formula of reinforcement overlap length when sleeve grouting overlap connection was adopted was calculated，which provided a theoretical basis for reinforcement connection in assembled shear wall.

Key words:reinforcement overlap connection;sleeve grouting;assembled structure;bond slip
