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。 According to the data of engineering investigation and static pressure pile construction in Zhengdong New District, the formula for calculating the ultimate bearing capacity of single pile in static geotechnical investigation rules of high-rise building is concluded. Based on the engineering practice of East New District, the test data of each section were statistically analyzed, the correction coefficient of pile tip resistance and friction coefficient of pile side were modified, and the empirical formula suitable for the geological conditions in Zhengdong New Area was established. The reliability of the formula , Which provides a valuable basis for the future engineering design and construction.
