The φu=0 analysis has been successfully used for the stability analysis of earth structures on cohesice soil stratum at or near end of construction. A design graph for low embankment with surcharge is compiled using circular slip surface by the φu=0 analysis for the case when the undrained strength of soil increases linearly with depth. By applying to stability analysis of two case records, an accuracy of the graph is found to be satisfactory.
　The same analysis is applied to the problem of bearing capacity of rectangular footing with assumption of cylindrical slip surface. The value of bearing capacity by the present analysis is found to be between those by Terzaghi and Skempton. The ultimate bearing capacity of strip footing for the case of inclined uniform loading and also for the case of earthquake is briefly described in the appendices.
