摘要
桥梁的抗倾覆稳定性对桥梁的结构安全、使用寿命等影响很大,本文以工程实例为依托,通过有限元分析软件对预应力砼现浇箱梁曲线桥进行设计和验算,对其抗倾覆稳定性影响因素进行了研究,并提出了预应力砼现浇箱梁曲线桥倾覆防控措施,为类似的曲线桥梁抗倾覆设计提供参考。
The anti-overturning stability of the bridge has a great influence on the structural safety and service life of the bridge.Based on the engineering example,this paper uses the finite element analysis software to design and check the prestressed concrete cast-in-situ box girder curved bridge,and its anti-overturning resistance is calculated.The influencing factors of stability are studied,and the prevention and control measures of prestressed concrete cast-in-situ box girder curved bridges are proposed to provide reference for the anti-overturning design of similar curved bridges.
