Abstract: Through the foundation design ofa chemical factory,a living example of composite foundation used in soft soil consisting of pressure pumped lean and plain concrete piling by continuous auger drilling in project was introduced. It is showed that the carrying capacity of tlus composite foundation is high, the sedimentation is small, and the economic efficiency is high.
Keywords: composite foundation; continuous auger drilling; lean and plain concrete piling
