摘要
基于桩基静载荷试验所得的沉降量数据具有一些灰色特征,将荷载Q看作广义的时间,建立了荷载序列的等步长及非等步长GM(1,1)预测模型。工程应用结果表明,所建立的GM(1,1)模型在预测单桩沉降量方面具有较好的实用性和可靠性。
Since the settling volume of single pile obtained from a static load test has gray characters, Load Q is considered as generalized time and forecasting model of GM （ 1,1 ） is established with equal step distance and unequal step distance of load sequence. The results of engineering application show that the model of GM （ 1,1 ） is practicable and reliable in forecasting the settling volume of single pile.
