Based on the results of static loading tests and measurement of axial forces
the load-transferring mechanism and deformation behavior of vertically loaded cast-in-situ piles with expanded branches and plates are investigated and discussed through a pratical project. Further,an equation is developted to calculate the vertical bearing capacity. The results illustrate that the expanded branches or plates support the vertical load in excess of 50 % in post-loading; and the resistance of expanded branches or plates behaves as end-bearing force. The bearing capacity of the new type of pile increases as great as about 60 %-100 % over the common pile with constant cross-section.
