摘要
对某双线铁路箱形梁水化温度场进行试验设计和监测,用有限元方法模拟边值条件和水化作用,仿真实际混凝土温度场,并在此基础上进行了几种特定条件下的箱形梁温度场和内外温差分析,给出了温度控制原则,以供借鉴。
The paper design trial and monitor hydration temperature field in double-line railway box girder,simulate hydro-heat action of the cement and boundary conditions by FEA and imitate concrete temperature field;furthermore,analysis temperature field and difference in temperature inside and outside of this railway box girder under several special conditions,and come out temperature controlling principles.
