Combining the engineering instances with the correlative specification in China and other countries, the author discusses the possibility of the application of the prestressed concrete pipe pile in the weak crystal sulfate corrosive geology and decomposed carbonic acid corrosive geology from the high strength, durability and permeation resistance.  The antiseptic measures are expounded from the selection of materials and mix-ratio,structural design and other aspects.
Keywords:  prestressed concrete pipe pile; corrosive geology; antisepsis
