An unequal time interval forecasting model of GM (1, 1) is established according to the grey theory in the present paper, which can be modified using the residual error GM (1, 1) model.
运用灰色理论建立了软基沉降的不等时距预测GM(1, 1)模型，并可用残差的GM(1, 1)模型对其进行修正。
The results show that when to data to be observed is unequal interval, it is more effective for the grey-chaos time series to analyse the data.
结果表明，当观测数据为非等时序列，采用灰色混沌时间序列进行分析比较有效；
The error analysis by the Time-data -Separation Approach of unequal interval sequence is difficult.
对于非等时序列的时数分离可以建立模型，但这种模型误差分析较困难。
