| 摘要： | The phenomenon of a bridge surrounded by or unilaterally close to a fill is often encountered in practice.In the case of a fill adjacent to a bridge with pile foundations,the lateral loads acting on the piles are induced by the soil settlement and lateral displacement.The piles were thus forced to deflect,inducing deformation and damage of the piers and the superstructure.In this paper,the influence of surcharge loads on an adjacent bridge is analyzed based on a real project.Additionally,the degrees of bridge injuries are evaluated and the corresponding strengthening strategies are proposed,which can be used as a reference in disaster prevention,strengthening and maintenance of similar bridges. |
