At first, this paper conducts in depth research on classification method, compaction propeties, granulometric composition and crushing of stone. On the basis of clarifying engineering characteristics of material of rock-filling embankment, requirements of ground treatment have been put forword in this paper. Then combined with the site test and engineering practice in SHUINAN Road and LANLIN Road, through the synthetical analysis of factors of influencing densification effect for the maximum grain size of filling material, lay-down thickness, granulometric composition, densification machinery and densification frequency etc., this paper studies key technical problems about construction technologies for spreading and leveling of filling material, choosing densification machinery, densification technology and slope construction systematically. Finally, construction technologies of filling lime-stone and sand-stone roadbed have been proposed in this paper ,which are significant for quality guarantee of highway engineering.

In order to solve the frost heave and thaw settlement, the model tests were made in Tibetan Plateau. Two kinds of model were designed to horizontal drain structure embankment and the ventilation embankment in suit. The effect of horizontal plastic drain was analyzed in contrast with the ventilation embankment. The mechanisms of horizontal plastic drain were studied in permafrost, such as gravity draining in the superficial layer and structure stiffing in the embankment in the theory. According to the design theory, the parameters of horizontal plastic drain were confirmed in the embankment. The values of deformation were inspected by fiber monitor system in the permafrost embankment.

The subgrade damages are divided into two-types: high subgrade and low subgrade damages. High subgrade damages of which are related to the embankment height and slope directions maily include longitudinal cracks and subgrade cracks. The higher of the embankment height, the greater of the happening rate. The mechanisms of high subgrade damages formation are analyzed by the observed dates of soil temperature within the embankment and damages survey. In warm permafrost regions, the damages are mainly caused by the formation and development of the thaw bulb and thaw layer. In cold permafrost regions, the damages are mainly caused by frozen bulges.
