On the basis of full analysis for anchorage foundation of suspension bridges at home and a-broad,and by combining engineering hydrogeological conditions of rock-socketed area,this thesis presents three schemes:installing caisson foundation,building island underground diaphragm wall foundation,and sunk well bored composite piles foundation,and by comparison of three kinds of schemes,sunk well bored piles composite anchorage foundation was selected.%依据对国内外悬索桥锚碇基础的充分分析，结合锚碇区的工程地质和水文条件，提出设置沉箱基础、筑岛地下连续墙基础、沉井钻孔桩复合桩基础等3种方案，并对3种方案进行综合比较，选择了沉井钻孔桩复合锚碇基础形式。
