【摘要】 采用模型试验和曲线拟合法，对砂浆和混凝土所形成的不同角度界面的试件进行轴向拉伸试验，导出界面开裂时正应力和剪应力的关系表达式作为界面开裂判据；把砂浆柱体从混凝土界面中压出，导出界面滑移时滑动位移和界面剪应力的关系表达式，作为界面滑移条件．运用这种方法研究砂浆和混凝土界面的开裂和滑移是简便和有效的更多还原

【Abstract】 By means of model tests and curve fitting, to deal with pull out tests of different angles at grout concrete interface, the equation of interface shear and radial stress at split stage is derived as interface split judgement; to deal with grout concrete interface pressure tests, the equation of interface shear and slip displacement at slip stage is derived as interface slip condition. By means of the method, the research of grout concrete interface split and slip is simple, convenient and efficient.更多还原
