Abstract: The pile-net composite foundation processing technology , that is horizontally reinforced and vertically strengthened , was used in highway widening project. And the technique was simulated by finite element method. The results indicate that the pile-net composite foundation treatment technology solves the problems of differential settlements caused by new and old roadbed and splicing quality of embankment. The vertical differential settlements caused by new and old roadbed and the horizontal displacement of new embankment are effectively controlled. Therefore , this technique can satisfy the requirements of highway expansion.

Key words: road engineering, foundation processing technology, settlement
