Abstract
This paper is intended to analyze the bearing properties and its affecting parameters of high-speed railway CFG-pile composite foundation by means of numerical simulation based on typical volume element and 3D model established with the software FLAC 3D. The static load curves of numerical simulation accord with the field test which means the model been taken are reasonable. Take different thickness and modulus of the cushion for analysis. The results prove that the settlement of the composite foundation decreased with the increase of modulus of the cushion. And the pile-soil stress ratio increases with the increase of modulus of the cushion. With the increase of the thickness of the cushion, the settlement of the composite foundation decrease, the pile-soil stress ratio increase, and the settlement on the top of the pile decrease. When the cushion thickness is over 500mm, neither the cushion modulus nor the cushion thickness would have influence on the pile-soil stress ratio.
