结合新版通用图,分析装配式预应力混凝土箱形连续梁桥通用图目前设计、施工以及应用中存在的主要问题,研究装配式箱梁的计算分析方法,对比分析横向分布系数法和梁格法计算结果的差别,研究分析了箱梁的合理梁高和腹板尺寸,系统地剖析了现行通用图在钢束设计、断面设计、其他构造处理等方面的技术改进。
Combined with the new general-purpose graph, the main problems existing in the design, construction and application of prefabricated continuous prestressed concrete box girder bridges are analyzed. The methods of calculating and analyzing the prefabricated box girder bridge are studied, and the transverse distribution coefficient method and grillage method are compared The paper analyzes and analyzes the reasonable girder height and web size of the box girder, and systematically analyzes the technical improvement of the existing general plan in aspects of steel beam design, section design and other structural treatment.
