Construction method of excavated roadbed of high-speed railway in deep artificial spoil area
The invention discloses a construction method of an excavated roadbed of a high-speed railway in a deep artificial spoil area. The method is characterized by comprising the following steps: step A, leveling the land of a site; step B, excavating artificial spoil in a layered mode, and carrying out slope brushing; step C, carrying out dynamic compaction on a cutting foundation base; step D, constructing a slope surface protection project of the arched framework of the cut slope; step E, constructing a cast-in-situ bored pile; step F, constructing a cast-in-situ bored pile top joist; step G, filling roadbed foundation bed filler; and step H, carrying out construction of affiliated structures of the cutting section. The construction method has the beneficial effects that the construction quality of the excavated roadbed in the deep artificial spoil area can be ensured, the stability of the side slope and the foundation of the artificial spoil cutting roadbed is ensured, the post-construction settlement of the foundation can be effectively controlled, the reliability of roadbed filling construction is ensured, and no disease is generated in the subsequent operation of the roadbed.
本发明公开一种深厚人工弃土地区高速铁路挖方路基的施工方法，其特征在于，包括以下步骤：A.对场地进行土地平整；B.分层开挖人工弃土，刷坡；C.对路堑地基基底进行强夯；D.施工路堑边坡拱形骨架坡面防护工程；E.施工钻孔灌注桩；F.施工钻孔灌注桩桩顶托梁；G.填筑路基基床填料；H.施工路堑地段附属构筑物。本发明可达到确保确保深厚人工弃土地区挖方路基的施工质量，确保人工弃土路堑路基边坡和地基的稳定性，能够有效的控制地基的工后沉降，保证路基填方填料施工的可靠性，确保路基在后续运营中不产生病害的有益效果。
