| description | The invention discloses a method for reinforcing an enlarged section of a two-way curved arch bridge, which specifically comprises the following steps that S1, the bearing capacity of a two-way curvedarch bridge foundation structure is rechecked, the enlarged section is reinforced on an old two-way curved arch bridge, the bearing capacity of an original bridge foundation structure needs to be rechecked before implementation, and it is guaranteed that the bearing capacity of the foundation meets the requirement after transformation; according to the foundation structure, the mechanical property of a foundation soil layer can be collected through underwater foundation inspection, on-site excavation and dynamic sounding means, then the quality of soil is detected, the bearing capacity of foundation soil is evaluated, and foundation structure parameters are recovered and subjected to checking calculation; by means of the method, an old two-way curved arch bridge can be effectively reserved, the bearing capacity o |
