寒区PC连续箱梁日照温度场测试与分析

摘要

By testing of PC continuous box-girder sunshine temperature field in Qiqihar Nenjiang river bridge of Heilongjiang province, the law of temperature variation and distribution of temperature difference in the roof, web and floor is analysed, the calculation formula of the temperature in box is summarized.%对黑龙江省齐齐哈尔嫩江大桥PC连续箱梁日照温度场进行测试,分析箱梁顶板、底板、腹板温度变化规律及温差分布规律,总结得出计算箱内温度的经验公式.
