Based on the overall temperature monitoring for frozen soil embankment with riprap slope protection and without riprap slope protection in Qingshuihe test section of Qinghai-Tibet Railway

the ground temperature

accumulated temperature and the maximum thawing depth variation in temperature field of these two kinds of embankments were analyzed. It is shown that the experimental embankment with riprap protection has better effect for its decreasing temperature

lowering minus accumulated temperature and lifting maximum thawing depth than that of the embankment without engineering measures. Therefore

the riprap slope protection embankment

as a positive frozen soil protection measure for its effectively decreasing ground temperature and being advantageous for slope surface protection

could be conveniently used not only for construction

but also for the future maintenance.
