| Abstract: | Based on the study on the environmental condition,hydrology,geology,waterway and other factors that might impact the Yongjiang extra-large bridge,the article performs optimum design to the main tower platform on the original design plan.It also uses finite element software to build the whole bridge and partial finite element model to perform struc-ture calculation and analysis,which ensure the feasibility of this plan and provides reference to related design. |
