BEARING CAPACITY ANALYSIS OF FOUDATIONS ON SLOPES BY USE OF LOG-SPIRAL SLIDING SURFACES

概要

論文の詳細を見る
This paper focuses on an extension of the log-spiral analysis of bearing capacity that has been presented in the authors' previous work for strip foundations placed on the level ground, to those on the top of slopes. Comparisons are made with other analytical and experimental results to examine applicability of the method to practical problems. It is revealed that the log-spiral analysis somewhat overestimates bearing capacity values as compared to other solutions, the errors involved being around 20 percent at maximum and varying sensitively to the angle of internal friction and slope inclination. Also noticed is a relatively good correspondence with experimental results, especially with model tests on clay (φ=0), on both the ultimate bearing capacity and the shape of sliding surfaces.
