Overhead roadbed structure, roadbed assembly, roadbed system and construction method
The invention belongs to the field of geotechnical engineering, in particular to an overhead roadbed structure, a roadbed assembly, a roadbed system and a construction method. The overhead roadbed structure comprises a bearing plate, a foundation bed surface layer is filled between the two retaining walls; a plurality of joists are arranged at the bottom of the bearing plate, at least two pile foundations are connected to the bottom of each joist in the length direction of the joist at intervals, track structure foundations are arranged on the surface layer of the foundation bed, buffer layersare compacted between the track structure foundations and the retaining wall, and when the number of the track structure foundations is at least two, buffer layers are also compacted between the adjacent track structure foundations. In the overhead roadbed structure, not only is the foundation treatment work amount is small, the occupied area is small, the use amount of filler is small, the construction quality is more controllable, the environment-friendly property is realized, the construction cost is lower, but also the dynamic stress, the dynamic displacement and the fatigue effect of thehigh-speed rail train on the bearing plate and the lower structure can be reduced, and meanwhile later operation and maintenance of the rail structure and the bearing plate are facilitated.
本发明属于岩土工程领域，具体涉及一种架空式路基结构、路基组件、路基系统及施工方法，其中架空式路基结构包括承载板，两个挡墙之间填筑有基床表层，承载板底部设置有若干根托梁，每个托梁底部沿托梁长度方向间隔连接有至少两根桩基，基床表层上设置有轨道结构基础，轨道结构基础与挡墙之间压实有缓冲层，当轨道结构基础为至少两条时，相邻轨道结构基础之间也压实有缓冲层。本发明的一种架空式路基结构，不仅地基处理工程量小、占地面积少、填料用量少、施工质量更可控、环保而且施工成本更低，而且，可减小高铁列车对承载板及下部结构的动应力、动位移和疲劳作用，同时也方便轨道结构和承载板后期的运营和维护。
