EMULATION ANALYSIS OF THE SOIL PARAMETERSprime|EFFECTS ON THE BEARING PERFORMANCE OF THE LARGE DIAMETER HOLLOW PILE

Using the MARC program, the authors analyze effects of soil parameters, such as cohesion, frictional coefficient, and elastic modulus, on the bearing performance of a large diameter hollow pile. The result shows that the elastic modulus is a controlling factor. The paper also evaluates the influence of the underlying soil,s modulus on the S e (the ratio of pile end settlement to pile top settlement) and the axial stresses. A close matching between the emulation results with the actual test data assures that the model is appropriate for analysis.
