摘　　要：大量水下工程的建设,对于水下不分散混凝土的材料性能和配筋梁构件的抗弯性能,国内外已有研究,但是对于水下不分散混凝土柱的受压性能,还未见报道。本文完成了水下不分散混凝土短柱的轴心受压实验,研究了受力性能,主要包括柱的破坏形态和承载能力等,并与普通混凝土柱进行了对比实验。基于实验结果的分析,探讨了现行规范中针对普通混凝土柱的计算方法对水下不分散混凝土柱的适用性。In recent years, with the development of the offshore and the construction of a large number of underwater engineering, underwater construction volume of concrete is increasing.The design technology of non-dispersible underwater concrete structures has become an urgent need to solve the problem. The material properties of non-dispersible underwater concrete and the bending performance of non-dispersible underwater concrete beams were studied at home and abroad. But the compression performance of non-dispersible underwater concrete columns have not been reported . In this paper, the axial compression performance of non-dispersible underwater concrete columns were experimentally investigated. The failure modes and loading capacity of the columns of non-dispersible underwater concrete were mainly discussed. Based on the analysis of experiment results, it can be proved that it is feasible to apply the current concrete design cede to calculate the loading capacity of the columns of non-dispersible underwater concrete.
