欧标及API规范桩基承载力设计

欧洲标准作为当前较新的设计标准应用逐渐广泛，其在桩基设计上采用分项系数法取代了传统标准中采用的安全系数法。分项系数可选择多个路径，并且可根据试桩情况，调整分析系数的数值，对于缺乏试桩的情况需对数值计算进行校正，设计方法先进。API-RP2A方法在桩基极限承载能力的计算上应用最为广泛。总结了几内亚力拓铁矿码头项目和几内亚阿联酋铝业码头项目中的设计经验，介绍了将欧标与API规范相结合进行桩基承载力设计的方法，并与国内2012版港口工程桩基规范进行了比较。

Evaluation of ultimate pile bearing capacity using Eurocode 7 and API-RP2A

Eurocode,as a new standard,is more and more widely applied in international engineering projects.By introducing a partial factor methodology against the traditional safety factor methodology,it provides multiple design approaches with adjustment of partial factors based on pile test availability,and is considered an advanced code.API-RP2A provides a most widely used method for evaluating the ultimate pile bearing capacity.This paper presented an evaluation method for pile bearing capacity by utilizing a combination of Eurocode 7 and API-RP2A based on experiences from the Simandou Project and the Kamsar Bauxite Jetty Project in Guinea,and gives a comparison to the Chinese Code for Pile Foundation of Harbor Engineering(2012).
