| Abstract: | The prestressed concrete pipe pile （PC pile） has been applied widely in the construction of highway, civil architecture, haven, and sea embankment etc. For it not only diminishes the settlement of foundation efficiently but also enhances the bearing capacity of foundation, PC pile composite foundation will be applied more and more. This paper introduced one calculation method of its pile-soil stress ratio and it was a better application in practical engineering. |
