摘　　要：调研了国内外大跨悬索桥的锚碇基础形式及相应的地质条件,总结了不同地质情况下常用的锚碇基础形式。根据调研结果,结合龙潭长江大桥北锚碇所在地地质条件,选取了适合本项目的地连墙基础形式,并对圆形地连墙基础形式和葫芦形地连墙基础形式进行比选。综合考虑经济性、施工的便捷性和受力合理性,选择了圆形地连墙基础形式。This paper investigates the anchorage foundation forms of long span suspension b ridges at home and abroad and the corresponding geological conditions,and summarizes the common anchorage foundation forms under different geological conditions.According to the survey results and geological conditions of the north anchorage of Longtan Yangtze River Bridge,the foundation form of the connecting wall suitable for this destination is selected,and the round foundation form and the gourd foundation form are compared.Considering economy,construction convenience and force rationality,the foundation form of circular ground wall is chosen.

关 键 词：锚碇基础 选型 圆形地连墙基础
