摘　　要：通过植筋的拉拔试验研究了焊接温度对植筋粘结滑移性能的影响,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拉拔力与植筋的滑移量变化曲线,并在试验分析基础上提出了设计和施工建议.By pull-out tests, this paper makes research of the effects of welding temperatures on the bond-slip behaviour of post-embedded bars, taking into account such factors as reinforcement diameters, anchorage depths and welding positions. Obtained are change curves of pulling and sliding capacities under the influence of welding temperatures, and presented are design and construction suggestions based on the test analysis.

关 键 词：植筋 焊接温度 滑移量
