Solution of the bearing capacity problem by the slip line method

The authors have derived the bearing capacity factor N-q on sloping ground based on the slip line method and have verified it using finite difference analysis. The bearing capacity factor N-gamma on sloping ground is obtained by an iterative finite difference solution of the slip line equations, and the results are close to those from laboratory testing. Design figures for N-gamma on sloping ground are prepared for rapid engineering use. For earthquake loading, the authors have applied the concept of equivalent horizontal acceleration and have derived N-q and N-gamma based on slip line analysis.
