摘要
本文通过对近百块新老混凝土粘结抗拉试件的试验研究，考察了粘结面的处理方法、粗糙度、新混凝土的强度及其浇筑方式、试验方法对粘结抗拉性能的影响规律。为阐明粘结抗拉机理提供翔实的试验依据，并为混凝土修补工程提供参考。
Based on the experimental study of nearly one hundred adhesive tensile test specimens of young on old concrete, the effects of specific factors on the adhesive tensile performance are investigated. These factors are as follows: method of interfacial treatment, interfacial roughness, strength of young concrete, pouring method of young concrete, testing method. The obtained experimental results can provide the evidence for clarifying adhesive tensile mechanism as well as the reference for the practical concrete structural repair methods.
