the embankment piles of plastic tube cast-inFplace concrete pile is a kind of rigid,sim-ilar to the use of foreign method,design and construction are already quite mature,but there is no use. And in our highway,railway,airport,municipal engineering,pile embankment has become a foundation treatment method for universal,its reinforcement in soft soil foundation treatment of a wide range of appli-cations.Compared with ordinary irrigation technology foundation pile,PTCC pile as a new foundation re-inforcement method has superiority and development prospect is.%塑料套管现浇混凝土桩也是一种刚性的路堤桩，国外类似方法有所使用，设计和施工均已比较成熟，但目前国内尚没有引进使用。并且在高速公路、铁路、市政、机场等工程中，桩式路堤已成为一种普遍的地基处理方法，其在软土地基加固处理上应用广泛。与普通地基桩浇灌技术相比，PTCC 桩作为一种新型地基加固方法有着相当的技术优越性与发展前景。
