In the construction of the D-runway in Tokyo International Airport (Haneda Airport), "the settlement prediction and management system (HSAP)" which can efficiently evaluate the consolidation settlement of artificial reclamation was developed. The reclamation history data base which reflected the actual construction until July, 2009 and the reclamation plan after that was made. The actual measurement and the calculation value were compared and the various consolidation parameters were identified. Moreover, the long-term consolidation test and constant strain rate consolidation test were executed, and the secondary consolidation parameter was set based on the isotache model's concept. Based on the prediction result of the residual consolidation settlement, the filling height of the D-runway at the start of in-service period was decided to be 0.70m, which is required from the aviation operation.
