摘要
简述现有桩基沉降预测方法存在的不足,结合桩基沉降的特点,引入灰色预测GM(1,1)模型,建立基于灰色GM(1,1)模型的单桩及群桩沉降预测研究模型,并给出其建模的原理及建模的过程。最后,通过工程实例,进行实证分析,研究表明该模型具有良好的适应性,能更好地反映桩基沉降变形的规律,提高预测的精度,具有良好的工程应用价值和推广前景。
The study briefly overviews the shortcomings of the existing prediction methods for pile foundation settlement, com- bines the characteristics of the pile foundation settlement, in this paper, the gray GM （1,1） model is introduced, and the settle- ment prediction model for both single pile and pile group is established based on the gray GM （ 1,1 ） model, also the modeling principles and process is giverr At last, the empirical analysis is applied by engineering instance, the study shows that the model has good adaptability, can better reflect the deformation discipline of pile foundation settlement, improve the prediction accuracy, so the study result has good engineering applications value and promotion prospects.
