摘　　要：新老混凝土结合面的连接性能是增大截面加固的关键难题。表面粗糙度、界面剂、修补材料、植筋等均是重要因素。目前各国规范对于抗剪计算均没有全面考虑上述因素,建议根据广泛的试验数据,建立包含上述影响因素的普适性设计计算方法。The connection performance of the new and old concrete joint is the key problem to increase the section reinforcement. Surface roughness,Interface agent,Repair material,Bars are important factors. At present, all the countries have not fully considered the above factors in the calculation of shear resistance, recommended according to a wide range of test data, A universal design calculation method with the influence factors is established.
