Reinforced hot melt pile/reinforced gravel pile composite roadbed structure in degenerated permafrost region
The invention discloses a reinforced hot melt pile/reinforced gravel pile composite roadbed structure in a degenerated permafrost region, and relates to a roadbed structure in the degenerated permafrost region, and aims to solve the technical problems that at present, road thaw collapse damage caused by permafrost region frozen soil degradation cannot be effectively controlled, moisture cannot berapidly discharged after frozen soil is thawed, a foundation becomes a soft foundation, the bearing capacity of the foundation is insufficient, and uneven settlement of a road occurs. The multiple reinforced hot melting piles and the multiple reinforced gravel piles are vertically arranged in the permafrost foundation, the upper-layer unfrozen soil foundation and the lower-layer unfrozen soil foundation. According to the novel roadbed structure for the degeneration type high-temperature permafrost region, two different pile bodies, namely the reinforced hot melting pile and the reinforced gravel pile, are used for forming a novel binary pile composite roadbed, the melting effect of heat released by the hot melting pile on frozen soil and the excellent drainage capacity of the gravel pile are combined, and pre-melting of the frozen soil and drainage consolidation of the melted soil can be achieved at the same time.
一种退化多年冻土地区加筋热融桩/加筋碎石桩复合路基结构，涉及一种退化多年冻土地区的路基结构。本发明是要解决目前由于无法有效控制多年冻土地区冻土退化而导致的公路融沉破坏，以及冻土融化后水分无法迅速排出，使地基成为软基，地基承载能力不足导致公路出现不均匀沉降的技术问题。多个加筋热融桩和多个加筋碎石桩竖直设置在多年冻土地基、上层未冻土地基和下层未冻土地基中。本发明所述的一种退化型高温多年冻土地区新型路基结构所使用加筋热融桩和加筋碎石桩两种不同的桩体形成一种新型的二元桩复合路基，结合了热融桩放热对冻土的融化效果和碎石桩优秀的排水能力，可以同时实现冻土的预融与融土的排水固结。
