摘　　要：通过两座不同施工背景下桥梁深水裸岩钻孔桩基础的施工实例,介绍不同施工条件下深水裸岩钻孔桩基础的施工方法及所采取的技术措施,探讨解决此类施工问题的主要方法和相关施工设备的选配,提出进一步提高施工效率及可靠性的有关设想。Based on the two examples of bridge bored pile foundations constructed under different conditions in deep water and uncovered rock, the construction methods and technical measures adopted for the construction of the piles under different conditions are presented. The ways to deal with the problems encountered in such type of construction and selection of suitable construction equipment are discussed, and the tentative ideas to improve the construction efficiency and reliability are provided as well.
