南京地区中风化较软岩地区嵌岩桩单桩竖向承载力计算分析

摘要

Through analyzing and comparing for new and old national code of pile foundation, local code, highway code,and railway code of pile foundation design on rock-socketed pile in Nanjing area, combined with engineering instances,a conclution can be drawn,which is the corresponding relationship of vertical carrying capacity of single pile among different codes. A reference for design of rock-socketed pile in the region is provided.%对南京地区嵌岩桩桩基设计中新旧国家桩基规范、地方规范及公路和铁路行业规范结合工程实例进行了分析比较,得出了不同规范所得单桩竖向承载力的相应关系,为该地区嵌岩桩设计提供参考.
