FIELD TEST STUDY OF REINFORCED EMBANKMENT SUPPORTED BY CAST-IN-SITU THIN-WALL TUBULAR PILES

To validate the working mechanism of reinforced embankment supported by cast-in-situ thin-wall tubular piles,field test has been performed in a highway section from Jiujiang to Xiaotang around Guangzhou City.Test results show that tubular pile has a large vertical bearing capacity,and punching failure happens to most piles in static tests.Moreover,the bearing capacity of single tubular pile composite foundation is also large with small...
