Abstract There are many cracks in subgrade in Qingshuihe experimental section after a freezing-thawing cycle. Different quantity of cracking occurs in the subgrade constructed by different engineering measures. Based on detailed investigation information of subgrade in Qingshuihe experimental section，the occurrence reason of cracking and classification of the cracking are studied. The situations of cracking in subgrade constructed by different engineering measures are also analysed.

Key words： soil mechanics Qinghai-Tibet Railway permafrost subgrade deformation cracking
