Estimating Ultimate Bearing Capacity Of Pressed-in Piles by CPT in Zhengdong New Developed Area
Author(s): 
Pages: 15-17,38
Year: Issue:  4
Journal: Geotechnical Investigation & Surveying

Keyword:  静力触探 静压桩 单桩极限承载力 修正系数;
Abstract: 根据郑东新区的工程勘察和静压桩施工资料,总结出了《高层建筑岩土工程勘察规程》中的静力触探估算单桩极限承载力的公式不适用于郑东新区;本文在郑东新区工程实践的基础上,通过统计分析各试验数据,修正了桩端阻力修正系数和桩侧摩阻力修正系数,建立了适用于郑东新区地质条件的经验公式,并验证了公式的可靠性,为以后的工程设计和施工提供了有价值的依据。
