A Slip-Line Analysis for the Bearing Capacity of Farm Land on a Sole Pan (Part 1)

Interfering Slip-Line Fields

Abstract

Bearing capacity of farm land which generally consists of soft soil on hard sole pan differs from that of homogeneous semi-infinite ground. 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.
