摘要

沉入饱和软土中的预制制桩的极限承载力随间歇期的增长而增大，这一现象虽已被工程界广泛认可，但至今仍然没有得到很好地解决。有效地确定单桩承载力随时间变化的规律对桩基础设计非常重要。人们提出了多种估算预制桩随时间变化的桩承载力的方法，但由于不同方法有各自的适用性和局限性，算出的结果有时差别很大，在使用时很难准确把握。首先分析了用于估算饱和软土中预制桩承载力随时间变化的几种方法：对数函数法、双曲函数法、人工神经网络法和基于超孔隙水压力消散的理论解析公式法。再以简洁性、理论性、适用性等为准则，结合工程实例，对以上几种方法进行比较，指出各自优缺点，推荐基于超孔隙水压力消散的简化解析方法来估算软土中预制桩承载力随时间变化的规律。

Abstract

The ultimate bearing capacity of single pile increases with time after pile installation

and it is of great importance to foundation design. Although several methods have been established to study this time-dependent ultimate bearing capacity of single pile

they have different occasions for application

and the deduced results of them may differ greatly. Firstly，the methods for determining time-dependency of single pile are summarized. Four typical types of methods namely: (1) empirical method using logarithm function; (2) empirical method using hyperbolic function; (3) soft method using artificial neural networks; (4) analytical method using consolidation theory

are analyzed in detail. Secondly

three criteria namely: (1) simplicity and parameters physical meaning; (2) theoretical meaning; (3) general applicability; are used to appraise the methods by two case studies. Finally

analytical method using consolidation theory

established by authors

is suggested to be basic method to estimate time-dependent ultimate bearing capacity of single pile.
