In allusion to this problem, First, based on interface structure characteristic, The cut and fill sub-grades slope is divided into two kinds in stair level, high-steep interface sub-grades slope and common interface sub-grades slope.

Stability analysis of part-cut and part-fill subgrade has been a great concern for highway engineers.

To analyze the influence of the asphalt pavement deformation under the non-homogenous settlement of the roadbed,authors use elastic-plastic dynamic FEM to compute the differential settlement of the half-filled and half-dug embankment under the traffic load.

The mechanical character of semi-fill excavation high filling roadbed and the construction control;

Construction techniques of semi-filling and semi-excavating subgrades in plateau and high-cold frozen earth areas;
