摘要
本文以一座三跨(17m+20m+17m)钢筋混凝土连续箱梁桥为工程背景,利用空间有限元来模拟真实的桥梁,进行空间受力分析,得出箱形梁桥横梁的内力分布特点,并用几种简化算法与其比较,得到比较接近实际的简化算法。
This paper summarizes the distribution features of internal forces in cross girder according to the finite element calculation on the background of one reinforced concrete box girder bridge with span arrangement（17m＋20m＋17m）, and compares with several simplified calculation method,get a better on which close to the real situation.
