摘　　要：以李坑子特大桥为例,对栈桥和平台进行初步设计,然后采用有限元软件Midas Civil建立栈桥和平台的三维有限元分析模型,并对其在不同荷载组合作用下的受力情况进行分析验算。分析表明,上部荷载作用下栈桥和平台的强度、刚度及稳定性均满足设计要求。Based on the Likengzi long-span concrete bridge,the trestle and platform are preliminarily designed,and then the three-dimensional finite element analysis model of the trestle and platform is established by using the finite element software Midas Civil,and the stress state of the trestle and platform under different load combinations are analyzed and checked.The analysis shows that the strength,stiffness and stability of trestle and platform under the action of upper load meet the design requirements.
