摘要
通过对不同钢纤维掺量的混凝土试块进行力学特性研究,其中采用劈裂法和套筒致裂法对钢纤维混凝土试件抗拉强度的分布特征进行分析,并对比普通混凝土力学特征数据,反映出混凝土在抗拉强度、韧性等方面得到很大提高。通过井壁模型试验的研究,钢纤维混凝土确实是千米深井井壁支护的理想材料。
in this paper, the concrete test block which has the different dosage of steel fibre will be used for mechanical properties research, including the splitting method and the sleeve crack method which are adopted to the distribution features of the tensile strength of steel fiber reinforced concrete specimen will be analyzed, and compared with the mechanics characteristic data of ordinary concrete, reflecting that the tensile strength, toughness, ere of the concrete have greatly improved. Through the study of the shaft wall model test, the steel fiber reinforced concrete is, indeed, the ideal material of the km deep well casing supporting.
