摘要
运用平面杆系方法,采用有限元计算程序桥梁博士3.2.0和BSAS4.22对预应力混凝土单箱双室简支箱梁桥进行纵、横向计算,分析了端横梁支座脱空的问题,并对比给出了三线梁与双线梁合理的钢索方案,计算过程和结果分析对同类桥梁设计具有参考意义。
Applying plane frame system, the paper carries out horizontal and vertical calculation of prestressed concrete single-box double-room simply-supported box girder by using finite element calculation program bridge doctor 3.2.0 and BSAS4.22, analyzes the horizontal beam brace cavity, and shows triangle-beam and double-beam cable scheme. Thus, the calculation process and results analysis will have certain guiding meaning for similar bridge design.
