Analysis of the Effect on Vertical Bearing Capacity of Prefabricated Single Pile Constructed by Static Pressure and Hammer-Driven Sunken Pile Pressure in Tianjin District

摘要: 通过对JGJ 94-94规范有关预制桩部分的编制说明及编制依据等资料分析,结合试验研究与工程实践对静压预制桩单桩竖向承载力的问题进行了讨论。研究表明:按《建筑桩基技术规范》(JGJ 94-94)估算的静压预制桩的单桩竖向承载力值远远低于单桩竖向静载荷试验实测值。

Abstract: Based on the experiemental research and engineering practice, Summarizing and analyzing the code of JGJ 94-94 in order to use and design reasonably static pressure prefabricated pile. It shows that the vertical bearing capacity of prefabricated pile according to the 《Specification for Pile Foundation of Building》(JGJ 94-94) is more less than that of practial test pile according to static loading test.
