摘　　要：北京亦庄新城新建太和桥由于受外部条件的制约,此处跨河桥的结构厚度被限制在80 cm以内,且为异型结构。据此选用多跨现浇预应力钢筋混凝土实体板结构。利用Midas有限元软件对主梁进行了建模计算,并且对挠度、抗剪、抗冲切等进行了补充计算分析,为相关设计提供参考。Taihe Bridge is newly built in Yizhuang of Beijing. The structure thickness of bridge crossing the river is limited within 80 cm because of the external conditions there. This structure of bridge is special.Based on it, the multi-span cast-in-situ pre-stressed steel reinforced concrete solid slab structure is selected. The Midas finite element software is used to carry out the modeling calculation of the main beam,and additionally to calculate and analyze the deflection, resisting shear and resisting punching, which can be referenced for the similar designs.
