Construction Monitoring of Self-Anchored Suspension Bridge with Inclined Tower
Inclined single-tower self-anchored suspension bridges feature a high adaptability to geological conditions but involve complicated structural behaviors during construction due to system transformation. The erection of the tower and main cable is accompanied by changes in internal loading and represents a challenge in bridge construction. This paper reports a new construction scheme for the tower and main cable, introduces the characteristics of temporary structures, and presents the monitoring and control method for construction, through a case study of the Yingbin Bridge. The responses of the temporary structures, girders, cables, and suspenders were monitored using a structural health monitoring system and analyzed using a finite-element model. The results show that the proposed construction scheme can satisfy the safety and quality requirements of bridge construction, and the finite-element model can reasonably predict the bridge behaviors in construction. This study is expected to promote the construction of self-anchored suspension bridges with inclined towers.
