摘　　要：基于有限元分析Ansys软件,采用非线性接触单元模拟锚索与钢套管两者之间的接触传力。分析在U形预应力锚索锚固方式下,锚索半径、锚索中心角对预应力闸墩应力分布的影响规律,为闸墩的结构设计和锚索布置提供依据。Based on the finite element theory and ANSYS software,the contact transmitted force between anchor cable and steel casing is simulated by using non-linear contact element.The influence law of pre-stressed pier stress distribution affected by anchor radius and central angle is analyzed based on using of U-type pre-stressed anchor,which provides a reference for the pier structure design and anchor arrangement.
