基础沉降变形的灰色预测方法

Modeling foundation settlement by the grey system theory

用灰色系统理论建立了基础沉降变形的GM（1，1）预测模型。在建模中考虑了沉降观测时间的不等步长性以及荷载变化对沉降过程的影响。通过实例对比计算，证明了该法的可行性。

A model for foundation settlement was set up by the grey system theory. The original model was revised according to the similarity of settlement process under different load increment. The influences of load variation on settling process were considered. It is proved to be feasible through the analysis of engineering example.
