钢筋混凝土预制桩单桩竖向承载力分析

STUDY ON VERTICAL BEARING CAPACITY OF PRECAST REINFORCED CONCRETE SINGLE PILE

传统的钢筋混凝土预制桩极限承载力预测方法,难以考虑单桩极限承载力影响因素的模糊性和相互关系,根据长期工程实践资料,提出并建立了钢筋混凝土预制桩极限承载力分析的人工神经网络方法,从而达到在施工过程中减少或不做试桩的效果。利用30根钢筋混凝土预制桩实测数据建立神经网络模型,5根桩做检验样本,证实了该方法在预测单桩的竖向承载能力时可以满足工程实际的需要。

The traditional methods for predicting the bearing capacity of precast reinforced concrete piles can not consider the fuzziness and inter-influence of the factors influencing the bearing capacity. According to long-term actual engineering data, the method of neural network is proposed to predict the capacity of precast reinforced concrete piles. So, test piles cannot or less be done during construction.
