| Abstract: | Aimed at the diseases of bridge built on soft foundation after construction such as cracks on the abutment and shear deformation on the support, the stress characteristics, causes of diseases and the developing rule of diseases were analyzed based on the reinforcement of a bridge on Dali-Lijiang Expressway, and several measures for reinforcement were proposed. The safety of later construction and operation of the bridge was guaranteed, and the successful experience provides reference for similar projects. |
