Introduction and experimental analysis of cast-in-place tubular pile

Cast-in-place tubular pile technology was introduced in this paper.Based on the in-situ test data,the engineering property of single pile and composite foundation were specially analyzed.It was 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.At last tubular composite pile foundation test indicate that it not only well meet engineering requirement in settlement and bearing capacity,but also with the following advantages good quality,low cost etc.
