【Abstract】 Based on the multi-freedom system with vertical compulsory vibration and the Kelvin model of soil,the paper carries out simulation calculation of sinking large diameter cylinder to determine the dynamic response, the peak stress in the cylinder and sinking feasibility.The results can be used to solve construction problems. The adaptability of the model was verified with site observations.更多还原
