摘　　要：为研究采用高强灌浆料的钢筋浆锚搭接连接的受力性能,重点考虑了钢筋直径、搭接长度等主要影响参数,完成了16组共96个试件的拉拔试验。试验结果表明,采用高强灌浆料的钢筋浆锚搭接连接的钢筋间接搭接长度不小于0.4 l_(1)时,采用高强灌浆料的浆锚搭接连接的最终破坏形态均为试件端部钢筋屈服或拉断,未发生锚固破坏,采用高强灌浆料的钢筋浆锚搭接连接的钢筋间接搭接长度可确定为0.4 l_(1)。To study the force performance of rebar lapping in grout-filled hole using high-strength grouting material,This paper carried out 16 withdrawing tests on 96 samples,with special consideration of some main influencing factors,such as steel diameter and overlapping length,etc.The test result showed that the final damage form of mortar overlap connection using high-strength grouting material is steel end yielding or breaking and no anchor damage happens when the steel overlapping length is less than 0.4 l_(1).Therefore,the steel overlapping length of steel-reinforced mortar anchor connection using high-strength grouting material could be determined to be 0.4 l_(1).
