Cast-in-place tubular pile technology is introduced. Based on the in-situ test data
the engineering property of single pile and composite foundation are specially analyzed. It is found that the cast-in-place tubular pile gives prominence to its vertical bearing capacity. At the same time
the pile can have large diameter which induced thin-shell effect that enable the pile with high horizontal resistance. Finally
the tubular composite pile foundation test indicates that it not only well meet engineering requirement in settlement and bearing capacity
