| Abstract: | 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. |

| Keywords: | hydraulic structure distribution law stress analysis U-type anchor anchor central angle anchor radius |
