摘　　要：在四川某大桥锚碇基础施工中,首次应用了地下连续墙框架基础,并且在地下连续墙的接头处采用了特殊接头施工工艺,实现了地下连续墙的刚性连接,增加了框架基础的整体受力性能。地下连续墙框架基础的使用,意味着施工过程中无需进行基坑开挖即可进行锚碇基础的施工,减少了施工步骤,缩短了桥梁建造的工期,节约了工程造价。实际施工表明,该类型基础在桥梁锚碇施工中具有一定的应用前景。In the anchor foundation construction of a bridge in Sichuan,the diaphragm wall frame foundation is applied for the first time,and the special joint construction technology is adopted at the joint of the diaphragm wall,which realizes the rigid connection of the diaphragm wall and increases the overall mechanical performance of the frame foundation.The use of diaphragm wall frame foundation means that the construction of anchor foundation can be carried out without foundation pit excavation,which reduces the construction steps,shortens the construction period of bridge construction and saves the project cost.The actual construction shows that this type of foundation has a certain application prospect in the bridge anchorage construction.
