| Abstract: | Based on the catenary calculation analysis theory, the article simplifies the open cable state of self-anchored suspension bridge into the flexible cable born by the deadweight load equally distributed along the arc length and the force action centralized at the suspended cable, and calculates and analyzes the un-stressing length of the main cable for the self-anchored suspension bridge of Clearing Water River in Chengdu City, which can be referred for the design and construction of the similar bridges. |
