Abstract:
Large displacement can occur in the cable saddle of the anchorage of suspension bridge built on the soft foundation under large pulling force, which can endanger the bridge structure. In order to prevent this, a post filling method with the anchorage of open caisson was proposed. The reverse torque caused by the weight of filling body can balance out the torque produced by the large pulling force, which can compensate and control the displacement in the anchorage. Based on the analysis of the impacts of displacement in the anchorage on horizontal displacement of main tower saddle, the determination method of filling quantity was proposed using the optimization principle. The variation of safety coefficient of anchorage foundation during the post filling process was investigated, which suggested that the construction using post filling method would not decrease the stability of anchorage. Finally, the construction technique of post filling was discussed and an example was introduced for an anchorage of bridge with the post filling method.
