摘　　要：对比分析了钻孔灌注桩和PHC管桩的优缺点,选取典型软土区段进行PHC管桩的线刚度、桩身强度和地基承载力计算分析。通过试桩确定在本项目工程地质条件下的PHC管桩的单桩承载力等参数,为施工图设计提供关键设计参数。确定PHC桩的沉桩工艺和特点,为后续大面积施工提供参考标准。This paper compares and analyzes the advantages and disadvantages of bored pile and PHC pipe pile.The linear stiffness,pile strength and foundation bearing capacity of PHC pipe pile has been calculated and analyzed in typical soft soil sections.The single pile bearing capacity of PHC pipe pile under the engineering geological conditions of this project has been determined through the pile test results,and will provide key design parameters for the construction drawing design.Confirmed the pile sinking technology and characteristics of PHC pile,and provide a reference standard for the subsequent large-scale construction on site.

关 键 词：PHC管桩 桩基对比分析 试桩 单桩承载力
