高韧性混凝土粘结界面力学分析

Mechanical Analysis on High Toughness Concrete Bonding Interface

针对高韧性混凝土修复技术,基于弹性力学模型,对高韧性混凝土修复结构中粘结界面内力进行分析,推导了界面正应力和切应力公式,建立了在复杂应力作用下高韧性混凝土修复结构的开裂破坏准则,为高韧性混凝土结构修复技术提供理论支持。

Aiming at high toughness concrete recovery technique, based on elastic mechanics model, the analysis on internal force of bonding interface in high toughness concrete recovery structure is made, the formulas of normal stress and shear stress of interface are derived, and the failure criterion of cracking of high toughness concrete recovery structure under the effect of complex stress is built, so as to provide theoretical support for recovery technique of high toughness concrete structure.
