土/水連成解析を用いた道路アセットマネジメント支援の試み

抄録

Presented is the trial of road asset management supported by soil/water coupled finite element analysis. For the highway embankments on soft foundation, excessive long-term settlement and deformation are usually seen as a result of consolidation settlement The authors consider that settlement and deformation of highway embankments are the indicators effectively applicable to predict deterioration of highway. The soil/water coupled finite element analyses are conducted in analyzing the 20 years old existing highway embankments and its predictability of settlement and deformation during and after construction is verified. Based on the results of the simulation, the performance modeling of highway is carried out and the predicted life-cycle cost is compared with cost actually needed in the past 20 years.
