摘要

通过对青藏铁路清水河试验段片石护坡、无片石护坡的冻土路堤和地基的温度进行的全面监测，对比分析了路堤体内及基底的地温、积温及温度场中最大融化深度的变化情况，结果表明，采用片石护坡措施的试验路堤，与对比段（普通路堤）相比，降温效果明显。负积温量值大于对比段，最大融化深度抬升幅度较大。因此，片石护坡能够有效发挥降低地温、保护多年冻土的作用，并有利于坡面防护，是一种施作方便，既能用于新建，又能用于补强的多年冻土主动保护措施。

Abstract

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.
