The invention provides a method for protecting an ice-rich cutting slope in a permafrost region. According to the method, the ice-rich cutting slope in the permafrost region is protected through the steps of cutting the slope of the cutting slope, positioning underground ice, removing the underground ice, backfilling holes, clearing accumulated snow, conducting ecological protection and carrying out slope surface maintenance and management. The underground ice is removed by adopting a method of combining direct excavation and high-temperature steam, and the melting depth is the depth of localseasonal frozen soil. The method is suitable for the slope with the gradient less than 1/1.5, and has the main advantages of being low in manufacturing cost, easy to operate and good in protection effect, and the problem of ice-rich cutting slope protection in the permafrost region is solved.
本发明提出了一种永久冻土地区富冰路堑边坡防护方法，该方法通过以下步骤：路堑边坡的削坡、地下冰的定位、地下冰的移除、空洞的回填、积雪清理、生态防护、和坡面养护管理实现了永久冻土地区富冰路堑边坡防护。其中，地下冰的移除采用直接挖除和高温蒸汽相结合的方法，融化深度为当地的季节性冻土深度。该方法适用于坡度小于1/1.5的边坡，其主要优点在于：造价低、操作简单、防护效果好，解决了永久冻土地区富冰路堑边坡防护的难题。
