摘要
该文简要介绍了GM(1,1)模型的建模及精度检验方法。依据单桩载荷试验中桩顶沉降随荷载变化的特征,建立了单桩极限承载力的预测模型,并通过工程实例对单桩极限承载力进行了灰色预测。
This paper briefly introduces the establishment and precision examination method of the GM(1,1) mod-
el. Based on the characteristic that the pile top settlement changes with the load during the single pile
plate load test, the grey prediction model of the single pile ultimate capacity was established. Moreover
by case histories, the grey prediction was conducted for the single pile ultimate bearing capacity.
