片石保温护坡是保护路基及基底下多年冻土的一种有效工程措施。对片石保温护坡寒、暖季降温效果的差异性从机理上进行了探讨,并结合青藏铁路清水河试验段片石护坡试验工程的测试数据,通过片石护坡路基与普通路基的地温对比,对片石护坡寒、暖季降温效果的差异性进行了分析,结果表明,片石保温护坡的降温效果,暖季比寒季好。

Insulating slab slope is an effective engineering measure for protection of subgrade and permafrost under base.The differences of cooling effect of insulating slab slope in cold season and warm season are discussed from mechanism.Combined with the test data of slab slope engineering in Qingshuihe test section of Qinghai-Tibet Railway,through comparison of the ground temperature of slab slope subgrade and ordinary subgrade,the differences of cooling effect of insulating slab slope in cold season and warm season are separately analyzed.The result showed that the cooling effect of slab slope in warm season is better than that in cold season.
