摘　　要：基于跨江、跨海工程的环境特点,这些工程将大量采用水下混凝土材料。水下不分散混凝土的设计技术成了迫切需要解决的问题,因此研究水下不分散混凝土的性能非常必要。通过立方体抗压强度试验、弹性模量试验和握裹力试验对水下不分散混凝土的基本力学性能进行了试验研究。通过对试验结果的分析,得到了水下不分散混凝土的立方体抗压强度、弹性模量、握裹力等力学性能指标。这将为今后编制水下不分散混凝土结构的设计施工规程提供相关依据。Based on the environmental features of works which span over rivers and sea, a large number of underwater concrete materials will be extensively used in these works.The design technology of non-dispersible underwater concrete structures has become an urgent need to solve the problem, so it is important to study the performance of non-dispersible underwater concrete structures.Through the experiments of the basic properties of the non-dispersible underwater concrete materials （ including cubic compression strength, elastic modulus, and the bonding performance with reinforcement）, the basic properties of the non-dispersible underwater concrete as well as the influence factors are studied.These conclusions on the mechanical performance will provide references to establish related design and construction regulations of non-dispersible underwater concrete structures.
