【摘要】 研究了新旧水泥混凝土接面不同毛面形式其接面强度的区别,通过对八种不同造型的接头界面的连接试验,找出了界面造型与接面强度关系的规律,提出了接面凿毛的最佳界面形式,得出新旧混凝土体对接时界面凿毛造型应是槽形为最佳的结论,并提出提高接面强度的方法和工艺,这一成果对桥梁施工工艺具有指导意义。更多还原

【Abstract】 This experiment has studied the intensity of new-old cement concrete connect by different form interface,the law of interface types & intensity has been discover by eight-kinds experiment.And the best interface form in joint has been make sure,that is to say the best form of new-old cement concrete interface is groove face.It’s to table a proposal of the way and technics,also to be make sense for bridge construction.更多还原
