锤击预应力高强混凝土管桩承载力特征值计算

Calculation of Characteristic Value for Hammer-driving PHC Piles

基于管桩基础设计实例分析,提出桩侧摩阻和端阻特征值取值不同于规范取值的建议,即摩阻力用统计分析的方法计算,端阻力则取《预应力混凝土管桩技术规程》的端阻修正系数予以修正。

Based on analysis practical examples of pipe pile foundation,suggestions to calculate characteristic value of friction and end bearing capacity are presented,that is,the value of friction bearing are calculated with statistical method and the end bearing are revised with raised coefficient in specification for pipe pile foundation.
