Anti-upheaval roadbed structure of ballastless track in cutting section and construction and design method thereof
The invention relates to the field of roadbed engineering and especially relates to an anti-upheaval roadbed structure of a ballastless track in a cutting section and a construction and design methodthereof. The structure comprises a bearing plate which is longitudinally arranged along a line, at least one side of the bearing plate extends into a slope soil body on a corresponding side, an elastic compression layer is arranged at a bottom of the bearing plate, two pile plate wall assemblies are arranged on the bearing plate at intervals in a transverse direction of a line, each pile plate wall assembly comprises at least two vertically-arranged anchoring piles, and the anchoring piles are connected with the bearing plate, penetrate through the bearing plate and go deep into a stable rockstratum. According to the anti-upheaval roadbed structure of the ballastless track in the cutting section, continuous upheaval deformation of the ballastless track cutting section in a soft rock deepcutting section can be effectively controlled, stability of a soft rock slope is guaranteed, and requirements of a high-speed railway for line smoothness and slope stability are met.
本发明涉及路基工程领域，特别是一种路堑地段无砟轨道抗隆起的路基结构及其施工与设计方法，其中，包括沿线路纵向设置的承载板，所述承载板至少一侧伸入对应侧的边坡土体中，所述承载板底部设置有弹性压缩层，所述承载板上沿线路横向间隔设置有两个桩板墙组件，所述桩板墙组件包括至少两个竖向设置的锚固桩，所述锚固桩与所述承载板相连接，所述锚固桩贯穿所述承载板，并深入稳定岩层中。本发明所述的一种路堑地段无砟轨道抗隆起的路基结构，能够有效控制软岩深路堑地段无砟轨道路堑地段持续隆起变形，保证软岩边坡的稳定，满足高速铁路对线路平顺性和边坡稳定性的要求。
