The subject of analysis is determined by wall rock displacement-time curve type, if curve type is stable type, the final displacement should be predicted, if curve type is unstable type, then the unstable time should be predicted. An integrated prediction and evaluation method, which named SDPM, is established, which takes residual standard deviation as basic indicator, the relative error, fitness, relative weight of the model is defined. Base on above research, the tunnel wall rock displacement time forecasting software is developed by Microsoft SQL Server 2000 database and Delphi program language, its main functions include predicting stable displacement of wall rock; predicting unstable time of wall rock; comprehensive prediction by SDPM method; and so on. Application cases indicate that the SDPM method and software is effective and convenient.
