摘　　要：升浆混凝土施工技术对专项加固港工建筑物水下部分有很好的适应性和独特的优势。结合港工上已采用的典型加固案例,阐述了该方法在加固破损的沉箱码头结构、增强重力式码头抛石基床稳定性和减小已有建筑物的沉降量方面的较大优势,对升浆混凝土的施工工法程序、特点和施工的技术要点进行了叙述和分析,是一种很好的就地加固方法,尤其适用于加固一些港工建筑物破损的水下部位或基础部分。采用升浆混凝土施工技术具有经济、方便、快速和安全的特点。The prepacked aggregate concrete construction technique is very suitable in strengthening the port structures under water. With the typical reinforcement cases, this paper introduces the advantage of the technique used on reinforcing destroyed caisson structure, strengthening the foundation stability of rubble bed, reducing the structure settlement volume. By introducing the construction program, construction characteristics and the key points, the technique is considered as a good method, especially in the destroyed underwater structures reinforcement. The technique has the characteristics of economical, convenient, quick and safe, and it is promising.
