季节性冻土区路基差异性沉降控制

Roadbed otherness settlement control in seasonal frozen soil region

分析了季节性冻土区域的路基温度分布情况,从大气温度和地表温度出发,得出沿路基深度的温度分布规律;研究了影响道路路基差异性沉降的地质条件和因素,探究温度、冻土类型、路基处理方式等对差异性沉降的影响;通过研究结果汇总,提出了季节性冻土道路路基沉降的预防措施,有效抑制了沉降的产生。为今后季节性冻土道路路基沉降的设计施工提供有益参考。

Analyzes the roadbed temperature distribution in seasonal frozen soil area, starting from the atmospheric temperature and land surface temperature, concludes temperature distributions along the depth of the subgrade; Studies the geological conditions and factors that impact on roadbed otherness settlement, explores the influence of temperature, types of frozen soil, roadbed treatment on otherness settlement; Through the results summary, seasonal frozen soil roadbed settlement prevention measures are put forward, which effectively restrain the settlement, provides useful reference for design and construction of seasonal frozen soil roadbed settlement in the future.
