欧标及常用美标打入桩桩基承载力计算对比

Calculation comparison for driven pile bearing capacity between Europe code and the US codes

打入桩桩基承载力的计算,是高桩码头、轨道梁等水工结构计算的重要组成部分。随着国内设计企业近几年走出去的步伐逐渐加快,一定程度上要求设计人员快速掌握并应用不同国家的设计理念和相关规范。对于桩基础,不同的设计规范和参考文献之间存在着一定的差异性,如何进行设计以满足安全性和经济性的需要,并符合相应国家的规范要求,是一个值得研究的课题。结合正在实施的海外项目的设计经验,选取国际上认可度较高的欧洲、美国规范及部分工程手册,通过横向对比,得出推荐的钢管桩桩基设计流程和参数,为海外项目桩基设计提供一定的借鉴和参考。

The calculation of bearing capacity of driven pile foundation is a key part in the design of maritime structure such as pile-supported wharf and crane rail beam.With the trend of domestic engineering enterprises expanding overseas markets,engineers are required to master and exercise design methods of different countries in a short time.As to the pile foundation,there are numerous design standards and references which are not consistent with each other in detail.How to carry out such a design that can satisfy safety and economic requirements,and compliant with related regulations,is worth studying.Based on engineering experiences from the oversea projects being executed,we present a recommended design procedure and parameters for calculating driven pile bearing capacity after comparing the methods in several wide-used resources,and can serve as a reference in other oversea projects.
