铁路双线隧道喷射钢纤维混凝土施工技术

Railway double line tunnel spraying steel fiber concrete construction technique

结合喷射钢纤维混凝土在铁路双线隧道中的应用实例,介绍了钢纤维混凝土配合比设计及喷射作业要点,探讨了采用带刚性组件的普通液压试验机进行钢纤维混凝土韧度系数和等效抗弯强度试验的方法,结果表明该方法取得了很好的效果。

Combined with the application of spraying steel fiber concrete in railway double line tunnel, it introduce the design of the adapted ration of the steel fiber concrete and the working points of spraying, discusses the methods of using the hydraulic experiment machine that with strip rigid component get the steel fiber concrete toughness coefficient and equivalent bend strength experiment, and the effect indicates that the method got the good effect.
