Abstract

Abstract: The research of temperature field and temperature effect on prestressed concrete box girder is carried out through artificial simulation of temperature increasing，which would finally result in the downward deflection of the prestressed box girder．

Key words: prestressed concrete box girder, temperature effect, experimental analysis

摘要： 采用人工控温模拟日照温差的方法对预应力混凝土箱梁模型进行了温度场及其效应的试验，摸索了预应力混凝土箱梁在日照温差的长期作用下的下挠特性。

关键词: 预应力混凝土箱梁, 温度效应, 试验
