摘　　要：通过对水下不分散钢筋混凝土柱和普通钢筋混凝土柱在轴向荷载和水平低周反复荷载作用下的对比试验研究,分析了两者抗剪承载力的区别以及影响水下不分散混凝土柱抗剪承载力的因素,如剪跨比、轴压比、配箍率等。试验结果表明,用规范给出的公式计算水下不分散混凝土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柱抗剪承载力的计算公式,计算结果与试验值较为吻合。The comparative experiments of shear strength between non-dispersible underwater reinforced concrete columns and normal reinforced concrete ones under axial and horizontal cyclic load are carried out in this paper.The differences of their shear strength and the effecting factors on shear strength of non-dispersible underwater concrete column are analyzed,such as shear span ratio,axial pressure ratio,hooped reinforcement ratio etc.The experiment results show that it is widely difference to calculate nondispersible underwater concrete columns by the standard formula.The shear strength formula of non-dispersible underwater concrete column is obtained through an amendment.The calculated results are corresponding with the experimental data very well.
