From the durability theory and current national standard,combined with the practical engineering of built high-rise building,this paper discussed the application of ultra long reinforced concrete piles in durability design and bearing capacity selection,the deep foundation pit to ultra long piles and the selection principle of pile end in soil layer,provided reference for similar engineering.%从耐久性理论和现行国家规范出发，结合已建超高层建筑的实际工程，对超长钢筋混凝土灌注桩在耐久性设计和承载力选择、深基坑对超长桩的影响以及桩端所在土层的选择原则等内容进行了探讨，为类似工程提供参考。
