摘要
Abstract
Where ballastless track is constructed in the area with seasonal frozen soil, the embankment deformation control is a prominent problem. The test of subgrade filled with coarse grain soil and the test of temperature and deformation of the natural foundation and insulated embankment are conducted to determine the relationship between different soil frozen index and frozen depth. Test results show that insulating layer can reduce the frozen depth prove to be an effective way to control subgrade deformation caused by frost heave.关键词
