摘要

讨论了预制桩承载力的主要影响因素，分析了桩基承载力随时间变化的规律。根据灰色系统理论，建立了灰色Verhulst预测模型。利用得到的灰色Verhulst预测模型对桩的极限承载力进行了预测。结果表明，预测值与实测值的变化规律是一致的，且误差较小，能够满足工程需要。

Abstract

Influential factors of the ultimate bearing capacity of jacked pile in clay are discussed. The relationship between the ultimate bearing capacity of jacked pile and time is analyzed. Based on the gray system theory

the gray Verhulst prediction model is proposed. Then the ultimate bearing capacity of pile is predicted by the model. The results show that the regularity of predicted ultimate bearing capacity is agreement with the measured ones; and error between predicted and measured value is small. So the gray verhulst prediction model can be applied to the practical engineering.
