Abstract: Through the single pile horizontal dead load tests of precast square concrete piles and prestressed concrete pipe piles, combining the current codes and standards, it made some analysis and exploration to the horizontal carring capacity of prestressed concrete pipe piles foundation and the anti-shearing force of prestressed concrete pipe pile body. It is concluded that the prestressed concrete pipe pile can be used safely in areas where the level of anti-earthquake is over 7 grade. Finally, according to the basic principle of material mechanics, it deduced the Japanese formula of prestressed concrete pipe pile's body anti-shearing force, and adjusted it to avail actual application in China.
Keywords: prestressed concrete pipe pile; shear bearing capacity; comparison test; aseismic
