Abstract The site of Shenzhen West Corridor Port was neritic zone and oyster land with lots of 7.0-24.0m mud and silt c1ay.The seae mbankments in east and south were at deep marine zone with great thickness of mud.Therefore,it was difficult to treat subgrade in soft soil zone. The different methods were proposed for treat the subgrade in soft soil zone because of the complexity of the engineering of filling sea and treating subgrade for Shenzhen West Corridor. To the outside sea embankments in east and south, they were filled by stones and treated by the method of explosive drain mud, along with strong consolidation. To the subgrade in soft soil zone within yard plateau, it was treated by the method of plastic drainage plate along with method of stockpile loading pre-pressure for drain water and consolidation. To the insulation embankment and transition zone between sea embankment and yard plateau , they were reinforced by sand pile. The bodies of insulation embankment and sea embankment were treated by strong consolidation. The practices show the application of the methods mentioned above are successful and worth being applied widely.
