钢管桩桩芯混凝土与钢管桩内壁粘结强度的计算,国内港工规范尚无明确的计算理论和计算公式。文章借鉴美国石油协会的《海上固定平台的规划、设计和建设——应力设计手册》(RP2A-WSD)中的计算理论和计算公式,并结合具体的工程实例进行分析和探讨,希望对今后类似结构问题的解决提供可借鉴之处。

In domestic codes and specifications for port engineering, there has been so far no definite theory and formula for calculation of the bond strength of the core concrete inside a steel tubular pile to the inner wall of the steel cylinder. Using the calculation theory and formulae specified in Planning, Designing and Constructing Fixed Offshore Platforms-Working Stress Design (RP 2A-WSD), edited by American Petroleum Institute(API) for reference, analyses were made on practical engineering examples in order to offer reference for dealing with similar structural problems in future.
