摘要：

According to geometry and mechanical characteristics of cable system at each construction stages for a self-anchored suspension bridge, two tensioning sequence for suspenders were determined, one is that side suspenders were tensioned firstly then the middle suspenders (TS1), the other is that side and middle suspenders were tensioned at the same time (TS2). Also, the construction methods of "multi-round cycles" and "step by step" were compared, then the optimal goals and parameters of system transformation was proposed. Based on the comparison of different plans of system transformation, the tensioning sequence for suspenders (TS1) was chosen as optimal scheme for the researched self-anchored suspension bridge, and some key calculated results at optimal scheme were compared with measured ones, the calculated results of structural response agree well with the measured ones, which indicated the feasibility, safety and controllability of the optimal scheme of system transformation for self-anchored suspension bridge.
