摘　　要：提出了基于整体最小二乘(TLS)综合考虑GM(1,n)模型中观测向量以及系数矩阵的误差,建立GM(1,n)模型,并将模型应用于某地区高铁的桥梁梁体上拱预测,结果表明,模型在高铁徐变监测中具有较高的精度、可靠性和适用性。This paper presents a method to model a GM （1, n） based on total least square. The error of observation vector and coefficient matrix arc also taken into consideration in the method. The model can be well applied to the prediction of creep appeared in the beam bridge in a certain high-speed rail projection. It can be concluded that the model is of superi- or precision, better reliability and well applicability in the monitoring of the high-speed rail creep.
