| 摘 要： | 大直径钻孔灌注桩竖向承载力的确定是桩基础设计的重要内容。通常采用经验法或试桩法来确定单桩竖向承载力。当试桩数量过少时 ,试桩法并不可靠。贝叶斯方法可以将有限的试桩数据与间接经验结合起来 ,以提高参数估计的精度并以大直径钻孔灌注桩为例 ,讨论确定单桩竖向承载力的贝叶斯方法。

| Abstract: | It is important to determine the vertial capacity of large diameter predrilled cast in place pile in the design of pile foundations,Ordinarily,the enpirical based method or the method on pile tests is used for a single pile.The results of testing on a few piles induce the method is unreliable.The Bayesian approach can combine the testing piles data's with indirect experiences to improve the accuracy parameter for estimation.The Bayesian approach for estimation of a single prefabricate pile is discussed. |
