摘　　要：水下灌浆是水工建筑物修补加固的重要方法。相较于水泥基灌浆材料,高分子基灌浆材料具有黏度低、可灌性好、凝胶固化速率快和弹性好等优势,适用于细小裂缝和活动裂缝的快速修复。然而,目前常用的高分子基灌浆材料用于水下灌浆时,存在力学性能差、黏结强度差、耐久性差和成本高等不足。文中结合常用的高分子基灌浆材料,分析了水下灌浆的难点,并从树脂主剂、固化剂和助剂3个方面归纳了水下灌浆材料的改性策略。最后,指出了水下灌浆材料的未来发展方向是绿色化和自修复功能化,以更好地适应复杂的水下环境。Underwater grouting is a crucial method for repairing and strengthening hydraulic structures.Compared to cement grouting materials,polymer grouting materials offer advantages such as low viscosity,outstanding irrigability,expeditious solidification rate and excellent elasticity.Therefore,they have obvious advantages in the quick and effective repair of narrow cracks and active cracks.However,the common polymer grouting materials used for underwater grouting show inadequacies which contain poor mechanical properties,low adhesive strength,poor durability and high cost.Herein,the difficulties of underwater grouting were analyzed combining polymer grouting materials and modification strategies of underwater grouting materials were summarized from three aspects:resin main agent,curing agent and auxiliary agent.Finally,the future development directions of underwater grouting materials were discussed,which pointed out that the future underwater grouting materials should be green and self-healing functionalization to better adapt to the complex underwater environment.
