| Abstract: | The finite element analysis software is used to conduct analysis of main span mid-span elevation and displacement maximum node point elevation for 7 parameters that have considerable influences on the geometry of long span pretsressed concrete continuous rigid-frame bridge.The values that cause influences on the main span midspan elevation and displacement maximum node elevation are obtained at the time the parameters are varying,and the principal parameters will have influences on the geometry of the type of the bridge are pointed out in accordance with their actually possible occurrence. |
