摘　　要：为进一步深入了解和掌握国际标准,针对灌注桩极限承载力,从计算公式、参数取值和安全系数等方面,对比分析了我国《建筑桩基技术规范》(简称《桩规》)和美国石油协会《Recommended Practice for planning,Designing and Constructing Fixed Offshore Platforms-Working Stress Design》(简称《API》)规范的异同;通过比较发现,中美规范单桩抗压承载力计算公式较为统一,《API》规范较为保守;单桩水平承载力两者相近,但考虑群桩效应,美标折减较多。To further understand and master the international standard,in terms of the design method of drilled piles,the similarities and differences among Chinese code Technical Code for Building Pile Foundation and American Petroleum Institute Recommended Practice for planning,Designing and Constructing Fixed Offshore Platforms-Working Stress Design are compared and analyzed.The comparative results indicate that calculation formulas of compression bearing capacity is consistent with them,and the result of API is more conservative.The horizontal bearing capacity is similar while the reduction for API is larger than Chinese code when pile group is considered.

关 键 词：标准 桩基承载力 抗压 水平
