Abstract: This paper calculates and discusses the strain properties of four reinforced sectional types of prestressed concrete berthing piles.It shous from results that the hoop pile with symmetrical arrangementis the best type for its higher ability of absorbing energy.By reasonalle design,prestressed cncreteberthing piles can be used as berthing facilities because larder strain energy may be developed before failure.

Key words: prestressed concrete berthing piles, strain absorbing energy

摘要： 本文对4种截面配筋型式的预应力砼靠船桩的应变性能进行了理论分析计算和讨论.结果表明,对称布置的箍筋桩吸能量最大,是最佳的截面形式;通过合理的设计,预应力砼靠船桩在破坏前能够产生较大的应变能,用作码头防冲设施是经济可行的.
