The article finally through analyzing of the Zhejiang YiwuBinwang bridge temperature load, obtained the CFST arch bridge temperature stress rules with the temperature load which is including from top to bottom and from margin to core of arch-rib when the temperature value、 steel pipe wall thickness value and marking value of concrete change. The rule is that the axial force、 bending moment, as well as the shearing force elevates along with the change of temperature increases, so the control section stress which is linear relationship is. The article further proved the change of steel pipe wall thickness and marking value of concrete is not remarkable influence on temperature stress and internal force of arch ribs control section.

文章最后通过对浙江义乌宾王大桥温度荷载分析，得出了在由上至下和由周边向核心呈梯度变化的温度荷载作用下钢管混凝土拱桥结构应力随温度值、钢管壁厚值和混凝土标号值变化时的规律，即：轴力、弯矩以及剪力随着温度变化值增大而增大；钢管混凝土拱桥主拱肋的控制截面应力值亦随之增大，基本呈线性关系；并通过计算论证了拱肋各截面应力、内力值同钢管壁厚的变化、核心混凝土标号变化无关。

The results showed that plastic deformation at both -70℃ and 180℃ made the dislocation density of AISI304 stainless steel increase with the increase of deformation. Martensite phase transformation was induced for deformation at -70℃, whereas it was not at 180℃. As the dislocation density increased, the breakdown potential of AISI304 stainless steel's passive film became a little more positive. As martensite phase content increased, it became more negative and pitting corrosion resistance decreased.

结果表明：加热180℃和低温-70℃条件下塑性变形均使AISI304不锈钢中位错密度随变形量增大而增加，AISI304不锈钢在-70℃条件下塑性变形时部分奥氏体相转变为马氏体相，而在180℃条件下塑性变形时不发生马氏体相变；位错密度的增加使AISI304不锈钢钝化膜的击穿电位略微正移，而马氏体相的增加使击穿电位呈负移趋势，材料耐孔蚀性能降低。
