When frozen soil layer freeze the volume increases, when forms the heave phenomenon, the melting, forms melts the Shen phenomenon. The serious heave, melts Shen back and forth to corrode, causes the engineering structure to distort possibly, causes the railroad line to lose smoothness, affects the train normal speed.
• some concrete structure, bridge present surface crack.
• the partial sector sand damage is more serious than the expectation. Tibet Autonomous Region's desertification land area reaches as high as 210,000 square kilometers, is one of global important sand storm places of origin.

Frozen permafrost layer volume increases, formation of frost heave, melting, melting phenomena form. Severe frost and thaw settlement between erosion, could lead to structural deformation, rail lines lost ride, the train is running normally. • Some concrete structures, bridges are surface cracks. • Some segments sand serious than expected. Tibet's desertified land has reached 210,000 square kilometers, is an important global source of sandstorms one. Geological sand for railway safety hurting unexpected. • Yak Road on outstanding issues, endanger passenger safety.
