| Abstract: |
Multi-pylon suspension bridge is the bridge type scheme that bridge workers dream of. The rigid mid-pylon suspension bridge is the best solution for multi-pylon suspension bridges with more than three pylons. Its core is to improve the anti-slip performance of the cable saddle. Through a large number of experiments and induction, the nominal friction coefficient of the cable saddle considering the lateral wall friction resistance is obtained, and then a cable saddle is proposed with high friction performance. The calculation method of the nominal friction coefficient and the anti-slip evaluation method of the cable saddle are given. On this basis, combined with the improvement of wind resistance performance, driving comfort and multi-span branching capacity, a "live-load anchorage design method" for multi-pylon suspension bridges was proposed, and it was successfully applied on the engineering example-"Wenzhou Oujiang North Estuary Bridge" project. |
