RAILWAY VIADUCT
PROBLEM TO BE SOLVED: To provide a railway viaduct with a ballast track laid thereon, the railway viaduct suppressing uneven displacement between viaduct structural bodies adjacent to each other in a bridge axial direction, at the same time suppressing displacement of the ballast track.SOLUTION: A railway viaduct 1 has a plurality of viaduct structural bodies 2, 2... arranged in a bridge axial direction X, and a ballast track 3 laid on the plurality of viaduct structural bodies 2, 2.... A first displacement suppressing body 4 is disposed on a side of the ballast track 3 in a direction Y orthogonal to the bridge axial direction, to be spanned between edge parts that face each other of a first viaduct structural body 2A and a second viaduct structural body 2B adjacent to each other in the bridge axial direction X. The first displacement suppressing body 4 is sandwiched between a side wall body (reactive force part) 22 and a plurality of sleepers 32, 32... of the ballast track 3 in the direction Y orthogonal to the bridge axial direction, the side wall body having been disposed in the bridge axial direction X on each of the first viaduct structural body 2A and the second viaduct structural body 2B.SELECTED DRAWING: Figure 1
【課題】バラスト軌道が敷設された鉄道高架橋において、橋軸方向に隣り合う高架橋構造体の不同変位を抑制し、バラスト軌道の変位を抑制できる鉄道高架橋を提供する。【解決手段】橋軸方向Ｘに複数の高架橋構造体２，２…が配列され、複数の高架橋構造体２，２…にバラスト軌道３が敷設された鉄道高架橋１において、バラスト軌道３の橋軸直角方向Ｙの側方に、橋軸方向Ｘに隣り合う第１高架橋構造体２Ａおよび第２高架橋構造体２Ｂの互いに対向する端部に架け渡されるように第１変位抑制体４が配置され、第１変位抑制体４は、第１高架橋構造体２Ａおよび第２高架橋構造体２Ｂそれぞれに橋軸方向Ｘに沿って設けられた側壁体（反力部）２２、およびバラスト軌道３の複数のマクラギ３２，３２…に橋軸直角方向Ｙから挟み込まれている。【選択図】図１
