Anti-arching roadbed structure of ballastless track in cutting section and construction and design method
The invention relates to the field of roadbed engineering, in particular to an anti-arching roadbed structure of a ballastless track in a cutting section and a construction and design method. The roadbed structure comprises a bearing plate which is longitudinally arranged along a line, vertical arm plates which are vertically arranged are connected to the two sides of the bearing plate correspondingly. The vertical arm plate is used for blocking a side slope soil body on the corresponding side of the cutting; wherein at least one side of the bearing plate extends out of the corresponding vertical arm plate and extends into the slope soil body on the corresponding side, the bearing plate is connected with a pre-stressed anchor cable, the bottom of the pre-stressed anchor cable extends intoa force holding layer, an elastic compression layer is arranged at the bottom of the bearing plate, and at least one pre-stressed anchor cable penetrates through the elastic compression layer. According to the anti-arching roadbed structure of the ballastless track of the cutting section, the arching deformation of the cutting section of the ballastless track of the soft rock deep cutting sectioncan be effectively controlled; meanwhile, the stability of a side slope is ensured, so that the requirements of a high-speed railway on line smoothness and the stability of the side slope are met.
本发明涉及路基工程领域，特别是路堑地段无砟轨道抗上拱路基结构、施工及设计方法，其中，路基结构包括沿线路纵向设置的承载板，所述承载板两侧分别连接有竖向设置的立臂板，所述立臂板用于阻挡路堑对应侧的边坡土体，所述承载板的至少一侧伸出对应的所述立臂板，并伸入对应侧的所述边坡土体中，所述承载板连接有预应力锚索，所述预应力锚索底部伸入持力层中，所述承载板底部设置有弹性压缩层，至少一个所述预应力锚索贯穿所述弹性压缩层。本发明所述的一种路堑地段无砟轨道抗上拱路基结构，能够有效控制软岩深路堑地段无砟轨道路堑地段上拱变形，同时保证边坡稳定，以满足高速铁路对线路平顺性和边坡稳定性的要求。
