摘　　要：根据牛顿插值平均法对非等时距基坑累计位移变化量进行等时距变换,结合灰色系统理论,建立非等时距灰色GM(1,1)模型,并采用VB与MATLAB编程语言对该模型进行编程实现,更加高效、直观、准确地对基坑变形进行了分析预报。结合某工程前数期的实测数据进行建模、分析和预测,取得了良好的效果。In this paper,non-equal interval cumulative displacement deformation of foundation pit is converted into equal interval data using Newton interpolation. According to the grey system theory,a non-equal interval grey model is established.Then it is achieved with VB and MATLAB programming language. And the predication of foundation pit deformation become more efficiently,intuitional and accurately to conduct. Finally,by using the measured data from a project in Qingdao city to model,analyze and forecast,the good effect is achieved.
