摘　　要：基于跨江、跨海、深水港工程的环境特点,工程中采用大量水下不分散混凝土材料,进行了水下不分散混凝土短柱的轴心和偏心受压实验,分析了水下不分散混凝土的破坏形态和承载能力.试验结果表明,水下不分散混凝土的抗压性能与普通钢筋混凝土的抗压性能具有相似的特征.Based on the environmental features of works which span over rivers and sea,or are in deep harbor,a large number of non-dispersible underwater concrete materials will be extensively used in these works.The axial and eccentric compression performance of non-dispersible underwater concrete columns was experimentally investigated.The failure modes and loading capacity of the columns of non-dispersible underwater concrete were mainly discussed.The experimental results show that the compression performance of non-dispersible underwater reinforced concrete columns and the common reinforced ones are similar in some aspects.
