中美标准中钢管桩桩芯混凝土设计方法对比分析

Comparative analysis of concrete core design methods of steel tubular pile in Chinese and American standards

结合孟加拉马塔巴里超临界燃煤电厂配套码头项目桩芯混凝土施工,对比中美规范对钢管桩与桩芯混凝土结构连接的有关规定,归纳总结出简便实用的拔桩力作用下的钢管桩与桩芯混凝土连接的计算方法,为后续海外桩基工程的桩芯混凝土计算提供参考。

Combined with the construction of pile core concrete for the supporting wharf project of Bangladesh Matabari Supercritical Coal-fired Power Plant,by comparing the relevant provisions on the connection between steel tubular pile and pile core concrete structure in Chinese and American standards,a simple and practical calculation method for the connection between steel tube pile and concrete pile core under the action of pile pulling force was summarized,which provides a reference for the calculation of pile core concrete in the following overseas pile foundation projects.
