ABSTRACT In cities along rivers, while a sudden flood can cause huge loss in economy, life and so on, the construction of flood control projects is an important issue of public construction. High strength prestress concrete pipe pile (PHC) has apparent advantage in capacity, deformation and construction, and recently been applied to flood dam. This paper discussed the theoretical superiority for applying PHC piles in levees, and verified that from a project in Wenzhou, in ways of situ test and ABAQUS finite element software simulation. Finally we proved the conclusion that PHC levee foundation can reduce sedimentation effectively and improve levee overall stability, additionally put reasonable proposals for application. KEYWORDS: PHC pile, project, ABAQUS, settlement calculation INTRODUCTION All over world, most cities are developed along river basin, because river offers great conditions for their development, but also poses serious threats to their security, that is flood. In ancient times, there are lots of problems from flood in human social life, mainly due to the randomness in time and space, and its paroxysm. Recently, PHC was applied widely in China, which is a new type of precast pile with high strength [1][2]. Compared with the general levee foundation design, applying PHC has many distinctive characteristics[3][4]: with industrialized technology, good pile quality, short curing time and - 5171 - Vol.
