[摘要] 分析了行业标准《混凝土结构后锚固技术规程》（JGJ145 - 2004）和国家标准《混凝土结构加固设计规范》GB50367-2006对于植筋锚固深度的规定，对比了二者间的差异，对于《混凝土结构加固设计规范》(GB50367-2006)中植筋位移延性修正系数ψ_ae的取值问题进行了探讨，分析了植筋锚崮深度小于钢筋锚吲长度的原因。

Abstract: This paper specifies the different stipulations about embedment length of bonded rebars, between "Technical specification for post-installed fastenings in concrete structures" JGJ145-2004 and "Design code for strengthening concrete structure" GB50367-2006. The value selection of Correction Factor of displacement ductility( ψ_ae)iS discussed. The reasons of embedment length of post-installed bonded rebars smaller than normal rebars is analyzed.
Keyword: bonded rebars; embedment length; correction factor;  displacement ductility
