摘要
温度应力的分析、温度控制和防止裂缝的措施,是大体积混凝土结构设计与施工中十分重要的课题。充分考虑到温度变化、弹性模量变化、徐变、自生体积变形等主要影响因素的共同作用,通过对某在建的大型闸室结构现场监测及温度应力场仿真分析,对大体积混凝土在施工期的温度场和温度应力进行探讨。
The issues of temperature stress analysis,temperature control and anti-cracking measures are very important for the structure design and construction of large volume concrete.Considering some infl uence factors of temperature changing,elasticity modulus changing,creep and self-volume deformation completely,and through some large lock chamber structure fi eld monitoring and temperature stress field simulation analysis,discussions of large volume concrete are made on the temperature fi eld and temperature stress during the construction period.
