摘　　要：为对海底隧道沉管未铺设基础进行后注浆处理,研发一种具备超低强度高流动水下不分散混凝土注浆材料。通过研究增粘剂掺量、胶凝材料用量、掺合料种类及掺量、水胶比对混凝土抗压强度、流动性、水下不分散性能的影响规律,总结了超低强度高流动水下不分散混凝土的配制方法。In order to carry out post grouting treatment for subsea tunnel immersed foundation without laying foundation,a grouting material with ultra-low strength,high flowability and underwater non-dispersible was investigated. The effects of the amount of viscoslty-modifying admixture, the amount of cementitious material, the type and amount of concrete admixtures, water binder ratio on the compressive strength,fluidity and underwater non-dispersibility of concrete were studied. The preparation method of ultra-low strength, high flowability and underwater non dispersible concrete was summarized.
