Numerical Analysis of Preventing Measures of Roadbed Problems in the Permafrost Regions of Yaling Railway
详细信息   
摘要

The roadbed problems are very serious in the permafrost regions in Northeast China. And manifold preventing measures are applied in experiment engineering to solve the roadbed problems. There are two sections (274K500275K000 m, 275K460276K000 m) in experiment engineering in the north region of Yaling Railway. And some active preventing measures such as insulated materials (XPS, EPS) and two-phase closed thermosyphon are applied in these two sections. Based on the data of temperature and geology in the region, the effectiveness of these measures is studied by numerical analysis method in this paper.
