Abstract: Jinshitan Bridge is the first self-anchored suspension bridge in China. Its total length is 198m,and the length of main span is(24+60+24)m. Some beneficial exploration and research is presented about the structure form design theory and internal force characteristics of the Jinshitan Bridge in this paper. Through computing the examples,the variational law of concrete self-anchored suspension bridges internal force is analyzed when the camber and the rise-span ratio are changed . And the law of the internal force affected by creep is also analyzed. Some conclusion can be consulted for designing and researching of this type of bridge.
