Abstract It is a new task of the motorway embankment foundation consolidation. At first, the construction sea area characteristic of the southeast littoral province was summarized. The conclusion was drawn that it was an effective method to driving the plastic drainage board in this geology condition. Driving the plastic drainage board could form the vertical drainage channel, accelerate the vent Of hole water and the concretion of clay, reduce the sedimentation after construction, enhance the load-bearing ability of the foundation. Based on describing the foundation consolidation mechanism of plastic drainage board, the embankment structure shape which should be used at the motorway embankment consolidating by plastic drainage board was introduced; along with the construction techniques and flow of plastic drainage board were recommended. Its Advantage and disadvantage were discussed at last.
