| 摘 要： | 针对我国桥涵设计规范未给出无铺装层钢箱梁日照温度梯度和采用实测方法确定其温度梯度工作量大的不足,根据热传导和有限元基本原理,应用ANSYS建立了江东大桥自锚式悬索桥一段无铺装层钢箱梁三维模型,求解了其温度梯度,并经现场实桥测试,实测值与计算值吻合较好.对钢箱梁日照温度场影响因素进行参数敏感性分析,发现吸收率对温度场计算...

| Abstract: | In design specifications for highway bridges and culverts of China,no solar thermal gradient is provided for the steel box girder without pavement,as a result,the solar thermal gradient has to be measured on site,which is a heavy work.This paper established a three-dimensional model for a section of the JiangDong Bridge steel box girder without pavement using ANSYS.The temperature field was calculated according to principles of heat conduction.The calculated temperature field at the scene of JiangDong Bridg... |
