摘　　要：在桥梁建筑施工过程中,泵送混凝土为高层索塔混凝土施工的主要方式,但泵送混凝土在其使用过程中易出现质量问题。加强对泵送混凝土的研究有利于减少泵送混凝土质量问题,提高工程施工质量。结合金堂韩滩双岛大桥主塔C55混凝土施工质量控制中取得的成效以及针对该工程制定的相关有效改进措施进行了分析与论述。During the process of bridge construction,pumping concrete is the main way for high-rise cable tower concrete construction;however,quality problems often occur during the application.Strengthening the research on pumping concrete is beneficial to reduce the quality problems of pumping concrete and improve the construction quality of the project.The analysis and discussion are made by combing with the achievements of C55 concrete construction quality control of the main tower of Hantan Twin Islet Bridge in Jintang County at present and the relevant effective improvement measures taken for the project.
