| Abstract: | The bucket foundations by the horizontal load was simulated by means of ABAQUS finite element software, and the results were compared with the model test results. The failure mode of a single tapered bucket foundation by the horizontal load in the saturated soft clay was studied by numerical calculations. On the basis of the numerical calculations with different parameters, we studied the impacts and relative sensitivities of soils’effective unit weight, undrained shear strength, bucket geometry, and loading position on the horizontal bearing capacity of a single tapered bucket foundation in the saturated soft clay. |
