摘要
Abstract
The traditional single variable or equidistant grey prediction model does not take into account the system correlation between monitoring points and the actual settlement observation cycle often has unequal interval characteristics, which is not enough to reflect the actual law of subgrade settlement deformation. In consideration of the correlation between the settlement point of each section of the actual condition and the nonequidistance observation, a optimized NMGM(1, n) model for prediction of subgrade settlement is established. The analysis of an engineering example shows that the optimized model is suitable for the modeling conditions. It has good fitting and prediction accuracy and can meet the needs of practical engineering applications.关键词
