摘要
单桩竖向承载力的确定是工程设计人员和基础施工人员最为关心的问题。针对预应力管桩基础设计中的单桩竖向承载力，提出了从经验公式计算、最后贯入度控制和高应变动测三方面综合确定的方法。
Determining the vertical bearing capacity of prestressed tubular pile is an issue which the designers are concerned about.Based on the vertical bearing capacity of prestressed single tubular pile,this paper proposes a method which the bearing capacity can be determined by the experienced formula,controlling the last penetration of pile and application of high-strain dynamic testing.Finally,the paper points out some problems that should be paid attention to in the design.
