摘　　要：作者在学习、执行《混凝土结构后锚固技术规程》JGJ145-2004,J407-2005的过程中,发现该《规程》7.0.3条关于锚栓(化学植筋)最小有效锚固深度比在一般情况下偏大,实际基材混凝土厚度难以满足《混凝土结构后锚固技术规程》对基材混凝土最小厚度的构造要求。为此,作者对确定锚栓最小有效锚固深度比的原则、方法提出几点建议,抛砖引玉,以求得安全、经济、可行的锚栓最小有效锚固深度比。Through studying and executing the Technical Specification for Post-installed Fastenings in Concrete Structures （JGJ145-2004 and J407-2005）, It＇ s found out that the minimal effective anchorage depth ratio about the anchor （ bonded rebars ）, described in the item of 7. 0. 3 in the Specification, is high in the ordinary course of events and the actual base material concrete depth id difficult to meet the detailing reauirements of minimal depth to the base material concrete stated in the Specification. Therefore, the author puts forward some suggestions on the principle and method of ascertaining the ratio to seek a safe, economical and preacticable minimal effective anchorage depth ratio.
