以大跨径悬索桥——西堠门大桥为试验平台,通过有限元理论分析和现场试验相结合,掌握了钢箱梁桥面板在车轮荷载下的局部应力分布规律,并对比分析了国内外几种主要的车轮荷载形式与试验结果的吻合程度。分析结果为车轮荷载形式的验证及其优化提供了必要的理论和试验依据。
Taking the large-span suspension bridge-Xitiaimen Bridge as a test platform, the local stress distribution rules of the steel-box girder bridge deck subjected to wheel loads are obtained through the combination of finite element analysis and field tests. The main wheel load form and test results match. The analysis results provide the necessary theoretical and experimental evidences for the verification and optimization of wheel load forms.
