400km-hour high-speed railway embankment structure suitable for Sichuan and Chongqing layer mudstone area
The invention discloses a 400km-hour high-speed railway embankment structure suitable for a Sichuan and Chongqing layer mudstone area, which comprises an embankment body layer, a subgrade bed lower bottom layer, a subgrade bed upper bottom layer, a subgrade bed lower surface layer and a subgrade bed upper surface layer sequentially filled from bottom to top. The embankment body layer and the subgrade bed lower bottom layer are filled with red mudstone cement improved soil, the subgrade bed upper bottom layer is filled with filler A and filler B, the subgrade bed lower surface layer is filled with graded broken stone, and the subgrade bed upper surface layer is filled with asphalt concrete. The high-speed railway embankment structure is simple in structure and can meet the design requirement of a high-speed railway subgrade with the speed of 400 kilometers per hour.
本发明公开了一种适用于川渝红层泥岩地区400km时速高铁路堤构造，包括从下而上依次填筑的路堤本体层、基床下底层、基床上底层、基床下表层和基床上表层，所述路堤本体层和所述基床下底层采用红层泥岩水泥改良土填筑，所述基床上底层采用A、B组填料填筑，所述基床下表层采用级配碎石填筑，所述基床上表层采用沥青混凝土填筑。该高铁路堤构造的结构简单，能满足时速400公里级高铁路基的设计要求。
