High-speed railway roadbed form suitable for goaf site and construction method
The invention relates to a high-speed railway subgrade form suitable for a goaf site. The subgrade form comprises bridge abutments, supporting seats, a suspension lane, a driving track and a water storage tank, wherein the two bridge abutments are positioned at the outer edge positions of two sides of a goaf, a bearing foundation pit is downwards excavated in the goaf site between the two bridge abutments, the water storage tank is arranged in the bearing foundation pit, the suspension lane is positioned between the two bridge abutments, an upper end face of the suspension lane is connected with at least two driving rails. The construction method comprises five steps of bridge abutment construction, foundation pit and water storage tank construction, suspension lane construction, suspension lane construction and deviation correction operation. On the one hand, adverse effects caused by differential settlement of a foundation can be eliminated, meanwhile, energy absorption can be conducted on vibration waves generated by train dynamic loads, on the other hand, the good adjusting capacity can be achieved on residual deformation of a goaf site, and meanwhile the good water corrosion prevention capacity and the good capacity of eliminating resonance effect transmission generated by the dynamic loads are achieved.
本发明涉及一种适用于采空区场地高速铁路路基形式，包括桥台、支撑座、悬浮车道、行车轨道、蓄水槽，桥台共两个位于采空区两侧外边缘位置处，其两桥台之间的采空区场地向下开挖承载基坑，承载基坑内设蓄水槽，悬浮车道位于两桥台之间，悬浮车道上端面与至少两条行车轨道连接。其施工方法包括建设桥台，基坑及蓄水槽建设，悬浮车道，悬浮车道建设施工及纠偏作业等五个步骤。本发明一方面可以消除地基不均匀沉降造成的不良影响，同时可对列车动荷载产生的振动波进行能量吸收，另一方面可对采空区场地剩余变形具有良好的调节能力，同时具有良好的防水蚀和消除动荷载产生的共振效应传递的能力。
