| 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。

| Abstract: | 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. |
