摘　　要：为了研究无支座单箱多室宽幅现浇箱梁横梁受力情况,旨在简化横梁静力计算便于工程实践,以一联三跨等截面宽幅无支座现浇箱梁桥为例,使用midas Civil 2019程序按照空间实用理论简化为平面杆系模型进行计算分析,为同类单箱多室现浇箱梁横梁的设计计算提供参考。In order to study the stress of single-box,multi-room wide-cast cast-in-situ box girder without support,the purpose is to simplify the static calculation of the cross-beam and to facilitate engineering practice.Taking a three span continuous cast-in-place box girder bridge with uniform cross-section and no support as an example,the Midas civil 2019 program is used to simplify it into a plane bar system model according to the space practical theory,so as to provide reference for the design and calculation of the same kind of single box multi chamber cast-in-place box girder beam.
