Frozen soil road foundation structure and construction method thereof
The invention relates to a frozen soil road foundation structure and a construction method thereof, belongs to the technical field of frozen soil area road foundation enhancement, and solves the problems of frozen soil degradation, road foundation stability reduction and the like caused by external water entering a foundation in the prior art. The invention discloses a frozen soil road foundation structure. The frozen soil road foundation structure comprises a steel sheet pile retaining wall and a foundation main body structure, the steel sheet pile retaining wall is vertically arranged on the inner side of the edge of the cross section of a roadbed in the runoff upstream direction, the bottom of the steel sheet pile retaining wall is inserted into a permanent frozen soil layer, the edge of the tamping layer is connected with the downstream side of the steel sheet pile retaining wall, and the upper surface of the tamping layer is flush with the earth surface. By means of the structure, external incoming water is effectively obstructed, especially underground runoff is obstructed, the problems of frozen soil degradation, foundation stability reduction and the like caused by the external runoff are avoided, the phenomenon of differential settlement of a roadbed is relieved and even avoided, the pavement condition of the frozen soil road is effectively improved, and the service life of the frozen soil road is effectively prolonged.
本发明涉及一种冻土公路地基结构及其施工方法，属于冻土区公路地基增强技术领域，解决了现有技术中外部的水进入地基导致冻土退化和道路基础稳定性下降等问题。本发明公开了一种冻土公路地基结构，所述结构包括钢板桩挡墙和地基主体结构；所述钢板桩挡墙沿径流迎水方向竖直设置于路基横截面边缘内侧，底部插入到永久冻土层中，所述夯实层边缘与所述钢板桩挡墙背水一侧相连接，夯实层上表面与地表平齐。实现了对外部来水的有效阻隔，尤其是实现了对地下径流的阻隔，避免了由于外部径流引起的冻土退化、基础稳定性下降等问题，减缓甚至避免了路基不均匀沉降现象的发生，有效提高了冻土公路的路面状况和服役寿命。
