摘　　要：在研究新旧混凝土粘结区面的特点及影响因素的基础上,将粘结断裂韧度作为判断新旧混凝土粘结性能的主要指标,应用断裂力学理论建立粘结断裂韧度函数,在试验的基础上应用方差分析理论分析主要因素对断裂韧度影响的显著性。结果表明:旧混凝土粘结面的处理方式对粘结面断裂韧度的影响是非常显著的,粘结材料及交互作用对粘结面断裂韧度也有显著的影响。It summarizes the characteristics of district face in new-old concrete bond, and definites the main factor of influencing bond. It also applies theory of fracture mechanics, establishes calculating formula in bonding fracture toughness, of which the fracture toughness is main index of differentiate concrete bond capability, provides variance analysis theory on the basis of experiment, and analyzes the main factor of notable influence on facture toughness. It provides reference for applied engineering.

关 键 词：断裂韧度 混凝土粘结 方差分析 显著性
