| 摘 要： | 深基坑降水过程中，建筑物产生的不均匀沉降变化具有系统性和不确定性。采用灰色系统理论建立了建筑物沉降量的系统预测模型MGM(1，n)。工程实例显示，与单变量GM(1，1)模型相比，MGM(1，n)模型有较好的精度和预测可靠度，对沉降预测有一定指导意义。

| Abstract: | During pits dewatering,non-uniform settlement of buildings has systemic and uncertain characteristics. The prediction model for the building settlement is suggested according to grey system theory. The engineering practice proves that MGM(1,n) model possesses rather better precision and forecast reliability comparing with GM(1,1) model,which will have positive influence on settlement prediction. |
