摘　　要：我国对水下不分散混凝土抗分散性能的测定已有相关的标准。但这些标准对水下不分散混凝土抗分散性能的测定是在静水下进行的,与实际施工的动水、深水高压等环境有所不符。动水环境对水下不分散混凝土的影响主要包括其对水下不分散混凝土浇筑过程的冲刷和对浇筑后未凝结硬化的水下不分散混凝土表面的冲刷两个方面。此外,不同水压对水下不分散混凝土的冲刷也存在一定的影响。就以上几方面研究中出现的国内外试验装置以及试验方法进行了综述,以期对复杂环境中水下不分散混凝土的抗分散性能的测试做出贡献。There are relevant standards for the determination of anti-dispersion performance of underwater non-dispersive concrete in China.However,these standards are used to measure the anti-dispersion performance of underwater non-dispersive concrete under static water,which is inconsistent with the actual construction of dynamic water,deep water and high pressure environment.The influence of hydrodynamic environment on underwater non-dispersive concrete mainly includes the scouring of underwater non-dispersive concrete pouring process and the scouring of underwater non-dispersive concrete surface without condensation hardening after pouring.In addition,different water pressures also have certain effects on the scour of underwater non-dispersive concrete.The domestic and foreign test equipment and test methods in the above aspects are reviewed,in order to contribute to the test of anti-dispersion performance of underwater non-dispersive concrete in complex environment.
