THE CHARACTERISTICS OF THE BEARING CAPACITY OF BUCKET FOUNDATION

Zhang Jian-hong

Open publisher page 4 citations

Abstract

The finite element software(ABAQUS) was used to simulate the bearing capacity of the bucket foundations with different height-to-diameter ratios. The characteristics of the bearing capacity of the foundations under the vertical loading,the horizontal loading and the coupling loadings were analyzed. The numerical results were compared with that of experiments. It is shown that under a critical vertical loading,the horizontal bearing capacity increases with the increase of the vertical loading,but decreases with the increase of the vertical loading when the latter is larger than the critical loading. The bearing capacity,especially the horizontal bearing capacity, increase obviously with the increase of the height-to-diameter.
