摘要: 探讨了采用地基–基础–上部结构共同作用分析的方法,分析长短 PHC 管桩基础的工作性能。该方法以变刚度调平理论 ^[1] 及地基–基础–上部结构共同作用理论 ^[2] 为基础,以瑞士开发的高性能岩土工程数值分析软件 zsoil.pc v2010 x64 版本为求解工具,提出了基于上述理论和工具处理长短 PHC 管桩基础的方法。还介绍了 3 个基于上述理论处理长短 PHC 管桩基础的工程实例,均取得了较好的处理效果。

Abstract: The soil-foundation-superstructure interaction analysis method is employed to analyze the performances of the foundation with long-short PHC piles. This method is based on the theories of adjusted foundation rigidity design for reducing differential settlement^[1] and soil-foundation-superstructure interaction analysis^[2]. High performance geotechnical software zsoil.pc v2010 x64 is employed to solve such problems. The approach to the tteatment of foundation with long-short PHC piles based on the above theories is proposed. Three projects of treatment of the foundation with long-short PHC piles are also introduced. Satisfactory treatment effect is obtained.
