摘　　要：通过对植筋的拉拔试验,研究了焊接温度对植筋粘结滑移性能和抗拔力的影响,考虑了植筋的直径、锚固深度和焊接位置3个因素,得出在焊接温度影响下植筋极限抗拔力和滑移量的变化情况,并在试验分析基础上提出施工建议。Effects of welding temperature on bond-slip behavior and ultimate strength of post-embedded bars was researched based on the pull-out tests. In the experiments three influence factors, reinforcement diameter, anehorage length, and welding position, were considered. The change of ultimate strength and slippage were obtained. On the basis of analysis, some suggestions are proposed for design and construction.
