关于抗拔桩设计的讨论

On design of uplift piles

随着城市地下空间的开发利用,抗拔桩的用量急剧增加。但抗拔桩设计有关的概念一直没有理清,各本设计规范也没有列出基础抗浮设计的公式。设计人员只能依据自己的理解,各行其是。同一工程不同人设计抗拔桩的用桩数量会相差数倍,有必要进行讨论。

With the development of urban underground space,use of uplift piles is in rapid growth.However there is still some confusion in design.The formula for anti-floating of foundations has not been solved in codes.As a result,based on their own experience,designers vary considerably in the number of uplift piles used in one project.It is necessary to further discuss the design of uplift piles.
