钢纤维喷射混凝土作为堆石坝面板材料的探讨

Feasibility Study on SFJC as Face Material of CFRD

钢纤维混凝土作为一种新型增强材料,以其较好的受力变形特性在水利水电、交通、海岸防护、港口及军事等诸多工程中已得到了广泛的应用.针对混凝土面板堆石坝面板的受力变形特点,为改善面板的受力条件,提高面板的防渗能力,同时方便施工,提出采用钢纤维喷射混凝土作为面板堆石坝面板材料的新构想;同时通过对钢纤维喷射混凝土的物理力学特性及堆石坝面板受力变形进行分析,为钢纤维喷射混凝土在堆石坝面板中实际应用进行了探讨,并提出相应的具体建议.

For the sake of improving the stress condition and enhancing the impermeability of the face slab, a new idea that steel fiber jet concrete (SFJC) is considered to be used as the material of the face slab of CFRD is proposed. The study is done for the research of characteristics and application of SFJC to construct CFRD conveniently.
