本文介绍了中跨258米的独塔预应力混凝土斜拉桥——宁波大桥的全桥空间受力有机玻璃模型的设计、组装及加载侧试等内容.文中对模型的理论分析与实测结果进行了对比,并对实桥桥面结构的受力状况进行了详细分析及评估,还对横梁及斜腹板内所需施加的横向及竖向预应力提出了建议.
This paper introduces the design, assembly and loading test of the full-bridge prestressed concrete cable-stayed bridge with a span of 258 meters and the bridge span of Ningbo Bridge.The theoretical analysis and the measured results of the model are carried out In addition, a detailed analysis and assessment of the mechanical conditions of the bridge deck structure are also given. Suggestions are also put forward for the transverse and vertical prestressing required in the crossbeam and diagonal webs.
