Hydrothermal protection roadbed structure in permafrost region
The invention provides a permafrost region hydrothermal protection roadbed structure which comprises a seasonal active layer foundation, and the seasonal active layer foundation periodically changes from a freezing state to a melting state along with seasonal changes. The permafrost foundation is located below the seasonal active layer foundation, and the permafrost foundation is in a frozen state throughout the year; the roadbed body is located above the seasonal active layer foundation, and the roadbed body is stacked into a structure with a trapezoidal section through roadbed filler; wherein protective road structures are arranged on two sides of the roadbed body. According to the invention, roadbed thaw collapse diseases caused by rainfall in permafrost regions, water accumulation at roadbed slope toes and the like can be reduced, and the long-term stability of the roadbed structure is improved.
本发明提出了一种多年冻土区水热防护路基结构，包括季节性活动层地基，所述季节性活动层地基随季节变化而周期性地从冻结状态和融化状态之间变化；位于所述季节性活动层地基的下方的多年冻土地基，所述多年冻土地基常年处于冻结状态；以及位于所述季节性活动层地基的上方的路基本体，所述路基本体通过路基填料堆积成截面为梯形的结构；其中，所述路基本体的两侧设置有护道结构。本发明能够减少多年冻土区降水和路基坡脚积水等引发的路基融沉病害的发生，提高路基结构的长期稳定性。
