摘要
热融湖塘是一种冻土区典型的地貌环境,其形成和发育受外界环境影响。文章分析了大兴安岭地区热融湖塘的形成条件,根据湖塘形态将其发育过程分为四个不同阶段,分析了各阶段湖塘的工程地质特性。指出由于热融湖塘从形成到完全衰退需要经历较长时间,不同时期的热融湖塘势必会对其上覆多年冻土产生热影响,进而影响其周围公路路基稳定性。研究提出了在不同发育阶段热融湖塘周围修筑公路的措施建议,以供同行参考。
The hot-melt lake pond is a typical geomorphic environment in the frozen soil area,and its formation and development are affected by the external environment.This paper analyzes the formation conditions of the hot-melt lake pond in the Daxing’anling area and divides its development process into four different stages according to the shape of the lake pond.The engineering geological characteristics of the lake pond in each stage are analyzed.Since the hot-melt lake pond needs to go through a long period of time from formation to complete decline,the hot-melt ponds in different periods will inevitably have thermal effects on the overlying permafrost,which will affect the stability of the surrounding roadbed.This paper proposes measures for building roads around hot-melt ponds at different developmental stages.
