| 摘 要： | 以魏家洲特大桥为例,按照我国公路桥涵设计规范、英国BS5400规范、新西兰规范确定不同的计算模式,对大跨径连续刚构桥进行温度效应分析,得出：温度应力在大跨径连续刚构桥整个桥梁设计中占有很大的比重,且采用不同的温度梯度计算模式,所得到的梁内温度应力值相差较大,甚至出现异号的温度应力.

| Abstract: | Weijiazhou extra-large-span bridge as an example, referring to specification of china JTJ023- 85 and JTF D60-2004 and British BS5400 and specification of New Zealand, different computation models of bridge structure are made and the effect of temperature on large span continuous rigid frame bridge is calculated. The results show that different temperature models reach discrepancy prodigious results, so much as contrary symbolic temperature stress. |

| Keywords: | computation model continuous rigid frame bridge temperature effect temperature stress |
