Variable cross-section bridge abutment and construction method
The invention discloses a variable cross-section abutment and a construction method, the construction method is applied to the variable cross-section abutment, and the variable cross-section abutment comprises two bearing platforms which are arranged at intervals in the transverse bridge direction; the pile foundation is arranged at the bottom of the bearing platform and used for supporting the bearing platform; one end of the platform body is supported on the top of one bearing platform, the other end of the platform body is supported on the top of the other bearing platform, and the height of the cross section of the platform body is gradually increased from the middle to the two ends; the table rear filler is arranged on the rear side of the table body, and the table rear filler is of an integrated rigid structure. Traditional filled earth behind the abutment is replaced by the filler behind the abutment, the filler behind the abutment is of an integrated rigid structure and has self-stabilization performance, horizontal loads cannot be transmitted to the abutment body, the horizontal stress condition of a pile foundation is improved, meanwhile, the height of the cross section of the abutment body is increased gradually from the middle to the two ends, the dead weight of the abutment body is reduced, and the construction efficiency is improved. Therefore, the vertical load of the pile foundation can be reduced, and the vertical stress condition of the pile foundation can be improved.
本发明公开了一种变截面桥台及施工方法，施工方法应用于变截面桥台，变截面桥台包括：两个承台，两个承台沿横桥向间隔设置；桩基，桩基设于承台的底部并用于支撑承台；台身，台身的一端承托于其中一个承台的顶部，台身的另一端承托于另一个承台的顶部，台身的横截面高度由中部至两端递增；台后填充物，台后填充物设于台身的后侧，台后填充物为一体式的刚性结构。通过将传统的台后填土替换为台后填充物，台后填充物为一体式的刚性结构，具有自稳性能，不会对台身传递水平荷载，有利于改善桩基的水平受力情况，同时，台身的横截面高度由中部至两端递增，有利于减轻台身的自重，从而有利于减轻桩基的竖向荷载，进而有利于改善桩基的竖向受力情况。
