摘　　要：通过对传统管桩截面进行凹面化处理,设计了罗马柱式预应力混凝土桩(罗马桩),并采用理论计算、试验验证和数值模拟相结合的方式,探究了罗马桩的抗弯性能。结果表明:同等条件下,罗马桩截面周长更长,可增加桩身与土体的接触面积;利用结构等效法可简化罗马桩截面参数的计算;罗马桩的抗弯性能与传统管桩相当。In order to increase the contact area between the pile body and the soil,improve the bearing capacity of the pile body,the Roman column style prestressed concrete pile was designed through the concavity treatment of the section.Theoretical calculation,test verification and numerical simulation were used to study the flexural performance of the Roman column style prestressed concrete piles.The results show that under the same condition,the section circumference of the Roman column style prestressed concrete piles is longer,which can increase the contact area between the pile body and the soil.The calculation of section parameters of Roman column style prestressed concrete piles can be simplified by using the structural equivalent method.And the bending strength properties of Roman column style prestressed concrete piles are better than that of the common piles.
