Reinforced concrete composite structure roadbed of expressway in permafrost region and construction method
The invention relates to a reinforced concrete composite structure roadbed of an expressway in a permafrost region and a construction method. Heat absorbed by the black asphalt concrete pavement in the permafrost region is conducted to a subgrade and a permafrost layer below, so that a melting disc is formed in the permafrost layer of the subgrade, and a thaw collapse phenomenon occurs. A pile foundation of the pile-slab foundation is vertically arranged; the pile plate foundation concrete slab is horizontally arranged above the pile plate foundation pile foundation; at least two steel webs are vertically arranged at the top of the pile-slab foundation concrete slab, and the bottoms of the steel webs are inserted into the pile-slab foundation concrete slab; the prefabricated concrete carriageway plate is horizontally arranged on the top of the steel web. The steel-concrete composite structure roadbed adopts the steel webs to replace high-standard filler, so that the overall self weight is light, and heat absorbed by the black asphalt concrete pavement can be prevented from being transferred to a frozen soil layer below; transverse connection beams are arranged between the steel webs to serve as energy dissipation components, and the purpose of structural aseismic design is achieved.
本发明涉及冻土区高速公路钢混组合结构路基及施工方法。冻土区黑色沥青混凝土路面吸收的热量向下方路基及多年冻土层传导，导致路基冻土层中形成融化盘，出现融沉现象。本发明的桩板基础桩基竖向设置；桩板基础混凝土板水平设置在桩板基础桩基上方；钢腹板竖向设置在桩板基础混凝土板顶部并纵向布置至少两个，钢腹板底部插入桩板基础混凝土板内；预制混凝土行车道板水平设置在钢腹板顶部。该钢混组合结构路基采用钢腹板代替高标准的填料，整体自重轻，可以阻断黑色沥青混凝土路面吸收的热量传递到下方冻土层中；钢腹板间设置横向联系梁作为消能构件，达到结构抗震设计的目的。
