桩基承载力计算方法的中英规范对比分析与应用

Comparative Analysis and Application of Calculation Methods of Pile Foundation Bearing Capacity Specified in Chinese and British Standard

安哥拉卡宾达地区有优质的海岸线,但码头资源非常匮乏。本文以卡宾达一新建港口工程为依托,比较中英规范标准对钻孔灌注桩竖向承载力的计算结果与现场试桩结果的不同,发现采用英国标准更接近现场试桩结果,并对建筑桩基技术规范中砂土地基中桩基承载力公式进行修正。对今后类似工程建设有一定的借鉴作用。

Cabinda of Angola possesses high quality coastline but scarce port resources.Based on new-built Cabinda port project,the field pile test result is compared with the calculation result of vertical bearing capacity of cast-in-place pile specified in Chinese and British Standard respectively,which shows the calculation result of British Standard being closer to the field pile test result,and leads to the formula correction of pile foundation bearing capacity for sandy soil specified in Technical Code for Building Pile Foundations.The above will serve as a reference for similar projects in the future.
