| Abstract: | Taking design works of low tower cable-stayed bridge in Dongsha-Xinlian expressway in Guangzhou as example finite element model is built based upon MIDAS/Civil 2006 program.Utilizing structural parameters in original design scheme the deformation,internal force and stress of control cross-section of bridge are calculated and analyzed through change the wall distance of double thin-wall piers.In the end based upon comparison of the stress values in control parts optimum rigidity of piers is selected. |

| Keywords: | low tower cable-stayed bridge double thin-wall pier change wall distance optimization study |
