Method for reinforcing enlarged section of two-way curved arch bridge
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 of the bridge structure can meet the design requirement for improving or maintaining the original design load effect, and the construction work amount and difficulty are reduced.
本发明公开了双曲拱桥增大截面的加固方法，该加固方法具体包括以下步骤：S1：对双曲拱桥基础结构承载力复核，在旧有双曲拱桥上增大截面加固，实施前须对原桥基础结构承载能力进行复核，确保基础承载力满足改造后要求；基础结构可通过水下基础检查、现场挖探、动力触探手段，采集基础土层力学性质，进而探测土的质量，评价地基土承载力，对基础结构参数进行恢复并验算；本发明既能有效的保留旧有双曲拱桥，又能使桥梁结构承载能力满足提载或维持原设计荷载作用的设计要求，减小建设工程量和难度。
