Application Of Prestressed Concrete Pipe Pile In Guangzhou-Lechang Highway

Vertical single pile bearing capacity，roadbed safety coefficient and the determination ofpost-construction settlement is the key to the design of prestressed concrete pipe pile infoundation treatment of highway. At present domestic about use of prestressed concrete pipepile foundation pile vertical bearing capacity of processing and roadbed stability safetycoefficient， the determination of post-construction settlement， is the use of LiZhengcalculation software to finish.On the basis of theoretical analysis above， In this paper， the guangzhou-lechanghighway more representative sections according to his engineering geology condition usingLiZheng calculation software to complete the subgrade stability safety coefficient andpost-construction settlement calculation. And take a detail instructions of the suitablegeological conditions of the prestressed concrete pipe pile， The classification of prestressedconcrete pipe pile and the needing attention of the prestressed concrete pipe pile inconstruction.
