| Abstract: | The author takes an extradosed cable-stayed bridge with single-cable-plane on Jiangmen- Zhuhai Expressway--main bridge of Hemaxi Bridge as example, studies the impact of primary struc- tural parameters on loading and displacement of the main girder, and analyses the reasonable height of the main tower of Hemaxi Bridge by adjusting primary structural parameters including height of tower, length of main girder without cables on the side of tower and midspan etc. |

| Keywords: | main bridge of Hemaxi Bridge height of tower length of main girder without cables on the side of tower length of main girder without cables on the midspan |
