摘　　要：　在对二次环抱牛腿粘结面进行受力分析的基础上,利用新旧混凝土粘结抗剪强度的试验研究成果,建立二次环抱牛腿粘结面的抗剪承载力公式,其中短牛腿公式经工程实例验证正确可行,弥补了现行技术规范的欠缺,可供设计参考。Based on the mechanics analysis of secondly-surrounding brackets, making full use of the research achievement of shearing strength in the bond interface between new and old concrete, the formulae of anti-sheared capacity for the brackets are introduced, and verified partly by some engineering examples. The study fills the gap in the norm, and offers consult for design.
