Abstract
The purpose of this paper is to analyze the different foundation treatments effect on road deformation numerically according to a widening practice. Results show that the plastic drainage board used in the new foundation enhances the old road deformation greatly during widening, while the new foundation with composite foundation produce less settlement of the new and old embankment after construction and disturbance to the existing road. At the same time, the distribution of the horizontal displacement in foundation provides the theory base to use the stress isolation wall to treat the new foundation. The wall depth depends on the depth of the horizontal displacement concentration zones.
