Analysis of the Innovative Structural Design of Liyutuo Lounge Bridge in Dujiangyan
Abstract
According to its design, the Liyutuo Lounge Bridge combines a multilayer frame structure with a large bridge structure, offering a solution involving a unique dual-use structure. The transport layer of the superstructure is a prestressed concrete rigid frame, and the pier, girder, and cross girder, are rigidly connected, and have typical characteristics of a prestressed concrete bridge structure and frame structure. For the structural design of pier foundations, the post-grouting and a combination of longitudinal tie beams are used to solve the challenges associated with a small pile diameter and large loads.
