Partial ground anchor suspension Bridges provide an economical and feasible technical solution for the construction of ground suspension Bridges under soft soil conditions, but the main beam has a large stress range due to the action of ground anchor force. In this paper, through the analysis of UHPC bridge panel and ground anchor force, the changes of UHPC on the stress and deformation of the main beam are obtained. In particular, the allowable ground anchor force under the allowable stress range of pavement layer is determined through the analysis of ground anchor force, which provides a reference for the corresponding main cable force, anchor size and retention anchor force.
