| Abstract: | The article analyzes the stress performance of bowstring arch after ship stroke by ANSYS,and discusses how to select the element type and to set up the constitutive relation model of the material.The article more completely considers the pile-soil interaction and puts forward the cautions for the simulating analysis according to the experience.Finally,the comparison with the measured data validates the truth and reliability of the simulating result,and the relative reinforcing measures are put forward for t... |
