Filling technology of blowing sand for high embankment in lake area;

Based on the application and practice using impact roller to a high embankment of highway,which is filled by soil-rock foundation packing material with high content of stone(60%–70%),an impact compaction technology for high embankment is developed.

This paper illuminates the high embankment of fast construction as the bridge prefabrication site from three aspects of processing natural subgrade,filling embankment and strengthen measures,and make it prepare for the construction,piling up,transport and assembly of prefabricated components.

Taking the road foundation construction of Luban Road of Nanning City as an example,this paper probes into the application of the technology for treating the soft foundation of high-fill roadbed in the case that the road passes through the complex topography and landform such as the gulch and pond.

high-fill roadbed has many diseases caused by the nature environment and vehicle payload more and more times.

This paper analyses the causes why the cracks occur, and introduces the methods of treating the settlement of high-fill roadbed.

Mechanism analysis of landslide induced by high-filled roadbed;

The application of the dynamic compaction on the high fill subgrade construction;

The deformation and stability of soils are still the two basic questions that the high fill subgrade confronts with.

The application of earth-fixing mat in herbage protection of high earth roadbed side slope;
