Study on development of recycle plan system for surplus soil

Abstract

A management of surplus soil come out from construction works in urban area becomes a serious social problem to be settled. So after this, effective use of surplus soil must be examined because some of them can be recycled as refill material after chemical treatment. However, distribution of surplus soil for recycle is more complicated than general soil distribution within earth work sites. This paper proposes a comprehensive recycle planning system of surplus soil including cutting sites, banking sites, treatment centers and stockyards, and make it clear that an optimal plan to minimize total recycle cost can be obtained by Linear Programming.
