摘要
弧形梁桥具有外形美观、线条流畅、动态感强等优点,越来越多的工程师在设计过程中青睐这种断面形式。弧形梁的结构受力比较复杂,有必要对其受力机制进行深入研究。通过对某高速路弧形梁桥的计算,找出弧形梁桥受力主控因素。在原设计断面基础上进行优化,最后确定合理的断面形式。
The curved girder bridges enjoy the merits such as artistic shape,smooth line and dynamic feeling,so more and more engineers are using this style of cross section in the design process.This structure is quite complex in stress under an external load.It is necessary to do a deeper research on its load mechanism.Through a curved girder bridge's study and calculation on a high speed road,we discover its main controlling factor of stress.Then the optimization in the original design is made and finally the reasonable cross section form is determined.
