摘　　要：以黑龙江省三股线高架桥的实测温度数据为依据,对竖向温度梯度的变化规律进行了研究,得出了该桥的竖向降温模式,并对本文研究的降温模式和公路桥规规定的竖向降温模式产生的温度自应力及外约束应力进行了计算与对比分析。分析结果为今后该地区桥梁的设计和施工提供了理论依据。The law of vertical temperature gradient is studied based on the temperature data of San Gu Xian viaduct in HeiLongjiang province, and the vertical cooling temperature patterns is got. Then, the comparative analysis of own stress and restraint stress which are calculated to this article model and highway bridge norm. In this paper, the results of the analysis provide a theoretical basis for the bridge design and construction in this region in future.
