The invention relates to the technical field of arch structures, in particular to an FRP double-segment concrete arch structure and a construction method thereof. The arch structure comprises an FRP double-duct piece, the FRP double-duct piece comprises an FRP outer duct piece and an FRP inner duct piece, the FRP outer duct piece and the FRP inner duct piece are arranged in parallel, and the FRP double-duct piece is in an arch shape; a plurality of FRP stirrups, wherein each FRP stirrup is arranged between the FRP double pipe pieces; and the concrete is filled between the FRP double pipe pieces. The invention has the advantages of simple structure, light weight, high strength, corrosion resistance and the like. The FRP double-duct piece can be used as a tensile member of the structure and also can be used as a light formwork for concrete pouring, transportation and construction are facilitated, the construction process is simplified, and the construction efficiency is improved. The FRP stirrup is used as an anti-shearing component, can improve the bonding performance of the FRP double-pipe piece and the concrete, effectively ensures the collaborative operation of the FRP double-pipe piece and the concrete, and is an important positioning component of the FRP double-pipe piece.
本发明涉及拱结构技术领域，尤其涉及一种FRP双管片混凝土拱结构及其施工方法。该拱结构包括FRP双管片，所述FRP双管片包括FRP外管片和FRP内管片，所述FRP外管片和FRP内管片平行设置，所述FRP双管片呈拱形状；若干个FRP箍筋，每个FRP箍筋均设置在所述FRP双管片之间；混凝土，所述混凝土填充在所述FRP双管片之间。本发明具有结构简单、轻质高强、耐腐蚀等优点。FRP双管片除了作为结构的受拉构件，又可以作为混凝土浇筑的轻质模板，便于运输施工，也简化了施工流程，提高了施工效率。FRP箍筋除了作为抗剪构件，既可以提高FRP双管片和混凝土的粘结性能，有效保证FRP双管片和混凝土的协同作业，又是FRP双管片的重要定位构件。
