1.Applying those engineering techniques, at present, the following results are obtained: the ground temperatures on the top and at the bottom of an embankment made of crushed rock are all lower than those of common embankment, so the crushed rock embankment is of great advantage of decreasing embankment temperature, and becomes an effective and initiative engineering measure to protect permafrost; the crushed rock embankment can actively adjust the temperature difference between south slop and north slop, and mitigate the asymmetry of ground temperature; the deformation of the crushed rock embankment is less than that of common embankment.

4.Results showed that the temperature distribution of the traditional embankment was asymmetrical; the asymmetrical status was changed after ripped-rock revetment was installed and the soil under the ripped-rock was cooled obviously; the ripped-rock revetment could cool embankment and adjust the temperature difference between the north-facing slope and the south-facing slope; the ripped-rock revetment was an available technique to protect embankment from thawing settlement and longitudinal cracks in permafrost regions.
结果表明:普通路基的阴阳坡两侧温度分布极不对称;铺设抛石护坡后,这种状况得到了很大改善,并且抛石护坡下土体温度明显降低;抛石护坡能够降低路基温度和调节路基阴阳坡的温度差异;抛石护坡是多年冻土区防治路基融沉和纵向裂缝病害的一种可行措施。
