Anti-frost heaving plate pile roadbed structure in cold region
The invention belongs to the field of roadbed structures, and particularly relates to a frost heaving prevention plate pile roadbed structure in a cold region. The frost heaving prevention plate pile roadbed structure comprises a foundation bed surface layer, an improved soil layer, an embankment layer and a concrete vibration isolation plate which are sequentially arranged from top to bottom. A pile foundation is arranged at the bottom of the concrete vibration isolation plate; a buffer groove and water-absorbing geotextile are arranged in the embankment layer, the buffer groove is centrally arranged at the middle lower part of the embankment layer, the top of the buffer groove is closed, the bottom of the buffer groove is open, and open holes for the water-absorbing geotextile to enter and exit are formed in the left side and the right side of the buffer groove; the compaction degree of filled soil in the buffer groove is 0.65-0.7; the water absorption geotextile transversely penetrates through the buffer groove in the width direction of the roadbed structure. According to the water-absorbing geotechnical cloth, water in the embankment layer can be moved forwards into the buffer groove, most frost heaving deformation can be achieved by controlling the compaction degree of filled soil in the buffer groove, deformation of the embankment layer is avoided, the influence on a roadbed structure is reduced, and the water-absorbing geotechnical cloth has remarkable social and economic benefits.
本发明属于路基结构领域，具体涉及一种寒区防冻胀板桩路基结构包括由上至下依次设置的基床表层、改良土层、路堤层和混凝土隔振板；所述混凝土隔振板的底部设置有桩基础；所述路堤层内设置有缓冲槽和吸水土工布，所述缓冲槽居中设置在路堤层中下部，所述缓冲槽顶部封闭、底部开放、左右两侧开设有可供所述吸水土工布进出的开孔；所述缓冲槽内部填土压实度为0.65～0.7；所述吸水土工布沿路基结构的宽度方向横穿所述缓冲槽；本发明的吸水土工布可将路堤层中的水分前移到缓冲槽中去，再通过控制缓冲槽内填土夯实度能够大部分冻胀变形，避免路堤层变形，减轻对路基结构的影响，具有显著的社会经济效益。
