摘要
为了通过预测单桩沉降量去估算其极限承载力,基于静载荷试验所得的桩基沉降量具有灰指数律特征,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。工程实例证明,所建立的灰色预测模型具有较好的实用性和创新性。
The paper is base on the settling volume of single pile getting from static load test that has gray index rule character in order to evaluate its ultimate bearing capacity through forecasting the settling volume of single pile. It considers Load Q as generalized time, establishes forecasting model of GM (1,1) with equal step distance and unequal step distance of load sequence. Proved by engineering example, the grey forecasting model is practicable and innovative.
