To resolve the design difficulties caused by small cross-section, low height of the bridge structure, the key technique problem to the bridge structure should be carried on research and analysis, such as whole calculation model, considering foundation combined action , the reasonable rigidity match to the joint of the girder and pier ,inner force redistribution caused by the system conversion ,the forecast to long-term deformation after building , stress analysis and tectonic steel bar of the anchored serration block , the influence of foundation settlement and anti- earthquake measures . To acquire feasible and reasonable technique parameters and provide the full design basis, according to analytical results adjust and optimize the bridge structure design.

为解决桥梁结构要求截面小，高度低等带来的设计困难，需对该结构的关键技术问题如考虑基础共同作用的整体计算模型、梁墩间的合理刚度匹配、体系转换产生的内力重分布、成桥后的长期变形预测、锚下锯齿块应力分析及配筋构造、基础沉降影响及抗震措施等进行研究分析，以获得技术可行、经济合理的技术参数，为设计提供充分的依据，根据分析结果调整优化桥梁结构设计。
