摘要
随着我国交通事业的快速发展,曲线梁桥被广泛应用。文中对珠三角某立交匝道桥进行仿真模拟,对内外腹板应力和主应力及内外侧支座反力进行了比较。
With the fast development of the national traffic,the curved bridge is adapted widely.This paper builds the finite model about one separated ramp bridge of pear river delta,analyzes the stress and the principal stress about the box girder outside and inside webs,and compares with the forces of the outside and inside bearing.
