摘要
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.
A series of work from design to testing of a three dimensional perspex model for the global structure and the deck structure of a single tower cable - stayed prestressed concrete bridge - Ningbo bridge with 258m main span is described in this paper. Comparisons between the tested and calculated results are conducted. Detail analysis and evaluation have been performed for the deck structure as well as the magnitudes of transversal and vertical prestressing forces in cross beam and inclined web are suggested respectively for the prototype of the bridge.
