In this study the bearing capacity of farm land for a vehicle which is regarded as two adjacent loads penetrating into soil on rigid pan in plane strain is analyzed by the slip - line method in order to establish a reasonable designing method for the traveling device of vehicles. Five types of the slip - line field are proposed for variation of load width and its interval., 論文}, pages = {3--10}, title = {耕盤のある圃場における支持力のすべり線解析(第1報) : 干渉状態のすべり線場}, volume = {60}, year = {1998} }
