Abstract
X-section cast-in-place concrete pile (referred to as XCC pile) is a new type of abnormal section pile developed in geotechnical research institute of Hohai University and patented in China. It has been widely applied in practice for its larger bearing capacity and use of less concrete than the common circular section pile. In this paper the construction techniques are introduced firstly, then comparative field study on load transfer mechanism of X-section and circular section pile rafts are presented. To reveal the bearing characteristics of the XCC pile raft foundations, the load-settlement relationship, side friction and so on are detailed analyzed. The results show that XCC pile raft has superior bearing capability compared with the circular pile raft, especially at the stage of high load pressure. The side friction percentage of XCC pile is larger than that of the circular pile while the tip resistance percentage is smaller.
