摘 要:通过对水下不分散混凝土短柱和普通钢筋混凝土短柱在轴向和水平荷载作用下的对比试验研究,分析了两者抗剪强度的区别以及影响水下不分散混凝土短柱抗剪强度的因素。试验结果表明,用规范给出的公式计算水下不分散混凝土短柱所得的结果与试验值相差较大,通过修正得出了水下不分散混凝土短柱抗剪强度的计算公式,计算结果与试验值较为吻合。

Abstract: The comparative experiments of shear strength between non-dispersible underwater reinforced concrete short columns and normal reinforced concrete ones under axial and horizontal load were carried out in this paper. The differences of their shear strength and the effecting factors on shear strength of non-dispersible underwater concrete short column are analyzed. The experiment results showed that it is widely difference to calculate non-dispersible underwater concrete short columns by the standard formula. The shear strength formula of non-dispersible underwater concrete short column is obtained through an amendment. The calculated results are corresponding with the experimental data very well.
