Differential settlement resistant transition section structure of ballastless track roadbed and construction method
A ballastless track roadbed differential settlement resistant transition section structure is used for effectively controlling differential settlement of a ballastless track road-bridge transition section and meeting the requirement of a high-speed railway for line smoothness. Comprising a pile plate transition structure and a filling body transition structure, the pile plate transition structure is arranged behind a bridge abutment and comprises a pile plate structure composed of a bearing plate and piles and a first filling body filled between the bearing plate and a foundation, and the longitudinal section of the first filling body is trapezoidal. The longitudinal section of the filling body transition structure is in a trapezoid shape, the front end of the filling body transition structure is connected with an inverted trapezoid at the rear end of a first filling body in sequence, and the rear end of the filling body transition structure is connected with an inverted trapezoid of a normal embankment structure filling body in sequence. A roadbed body and a foundation bed bottom layer which are sequentially constructed upwards from the foundation are arranged outside the two transverse sides of the second filling body, and a foundation bed surface layer is filled on the foundation bed bottom layer and the second filling body. And the rear part of the bearing plate extends into the filling body transition structure and is lapped and supported on the second filling body.
一种无砟轨道路基抗差异沉降过渡段结构，以有效控制无砟轨道路桥过渡段差异沉降，满足高速铁路对线路平顺性的要求。包括桩板过渡结构和填筑体过渡结构，桩板过渡结构设置于桥台之后，包括由承载板、桩构成的桩板结构和填筑于承载板与地基之间的第一填筑体构成，第一填筑体的纵断面呈梯形。填筑体过渡结构的纵断面呈梯形，前端与第一填筑体后端倒梯形顺接，后端与正常路堤结构填筑体倒梯形顺接，填筑体过渡结构的主体为采用级配碎石填筑的第二填筑体，在第二填筑体横向两侧外为从地基向上依次构筑的路基本体、基床底层，并在基床底层和第二填筑体上填筑基床表层。承载板后部延伸入填筑体过渡结构内搭接支承在第二填筑体上。
