摘　　要：考虑材料不同模量性的混凝土桥面板的计算是一个新的材料非线性问题,利用拉压不同模量理论,建立了研究不同模量混凝土桥面板结构的非线性有限元算法,编制了相应的计算程序,并对广东金马大桥主梁的桥面板进行了分析和计算,结果表明计算分析方法更精确,更为合理.The calculation for the concrete bridge deck slab of different elastic modules is a new material nonlinear problem. Using the theory of the different extension - compression elastic, the finite element numerical method and the computer program were established for the problem of bridge plate with different extension - compression elastic moduli. By the example calculation and analysis of the Jinma bridge, the calculation and research methods are considered to be more precise and logical.
