Abstract: Relying on a complete western highway expansion project, based on MARC finite element model, main considered different widening ways of old subgrade, widening width of embankment and embankment height effects on new and old roadbed deformation Then differential settlement were comparative analyzed.

key words: reconstruction; settlement of new and existing subgrade; finite element simulation; mechanical analysis; numerical analysis
