季节性冻土地区客运专线路基工程防冻胀措施研究

季节性冻土地区路基冻胀和融沉使路基产生不均匀变形,破坏轨道的平顺性,已成为影响铁路运行速度和安全的重大隐患之一。解决路基冻胀问题是季节性冻土地区路基设计的关键。文中结合哈大客专铁路路基工程设计,对季节性冻土地区铁路客运专线路基工程防冻胀措施进行研究。

Research on Anti-frost Heave Measures of Subgrade for Passenger Dedicated Railway Line in Seasonal Frozen Soil Area

In seasonal frozen soil area, the frost heave and thawing induces the non-uniform deformation of the subgrade to undermine the smoothness of the track, which has been a major hidden danger of the speed and safety to railway operations. The key technology of subgrade design is solving the problem of subgrade frost heave in seasonal frozen soil area. Based on the subgrade design in Harbin-Dalian passenger dedicated railway line, this paper carries out the research on the anti-frost heave measures of subgrade ...
