摘要
用优化方法对前人得出的静压桩复压力时效性增长曲线进行参数反演,确定反分析目标函数,通过工程试验检测数据的验证分析,认为根据反演所得增长曲线可用于估算其他施工方法、桩长、直径、场地地质等相似条件下的静压桩复压力增长,其结果可为静压桩设计及施工提供有益参考.
Parametric inversion is conducted for growth curve of the jacked pile re-pressure. Then the target function used for anti-analysis is determined. Through verification analysis on testing data in engineering, it is proved that the growth curve obtained by parametric inversion can be used to estimate the re-pressure growth of statically pressure piles with similar geological conditions, construction methods, pile length and pile diameter. The results of this paper are instructive and constructive to the jacked pile design and construction.
