建設残土の有効利用のための土量配分計画モデル

抄録

Although enormous volume of soil is excavated and discharged from construction works, disposal sites for the surplus soil decrease in urban area year by year. With this point as background, it is desirable to establish soil recycling system, that is effective utilization of soil between construction sites where surplus soil is discharged and other sites where soil is used as material for embankment, landfill, etc. In this study, three models for soil allocation are proposed corresponding to certainty of input data. (1) Model I is based on presupposition that all the relevant data are known deterministically. (2) Model II determines proper soil allocation in consideration of adjustment of working time on condition that input data for start time of each construction work has uncertainty. (3) Model III determines proper matches of construction works from the viewpoint of effective utilization of surplus soil.
