Therefore, it might be very essential to study the cable stayed bridge of the super breadth composite beam. additionally, the main problems of the study are as follows : 5 、 the distributing for stress of lengthways and transverse in transect ; 6 、 discussing the change of stress of lengthways and transverse, while the breadth of bridge is changing ; 7 、 in the cable stayed bridge of the super breadth composite beam, the lengthways reinforce rib and rigidity crossbeam exert influence on stress of bridge board ; 8 、 while tower and beam are concretion, main tower affects bridge board
鑒于目前關於此類橋型研究成果不多，就此作了下列若干問題的研究： 1 、超寬疊合梁斜拉橋橫斷面上縱向應力分佈和橫向應力分佈特點的研究； 2 、對超寬疊合梁斜拉橋隨著橋寬變化時，上述兩種應力分佈變化規律進行探討； 3 、在超寬疊合梁斜拉橋中，縱向加勁肋對橋面板受力的影響；橫梁尤其是剛性橫梁在橋面板受力中所起的作用； 4 、塔梁固結時，主塔對橋面板的作用。
