摘要
曲线梁桥与直线梁桥相比,主要区别在于其容易产生扭转,这样就存在弯曲扭转的耦合,而这种耦合也使得曲线桥梁的设计变得复杂。因此,设计人员必须在综合考虑各影响因素的情况下,结合工程实际情况,按照规范精心设计,才能确保曲线桥梁安全可靠。
The main difference lies in curved girder bridge is prone to reverse compared with the straight-line bridge,so that exist bending torsion coupling which also makes the design of curve bridge becomes complicated.Therefore,designers must consider various factors in the consolidated case,combined with practical engineering,design in accordance with the specifications to ensure curved bridge safe and reliable.
