摘要
超长连续混凝土板的温度效应十分显著,易造成楼板大开裂。采用有限元分析方法对超长混凝土板的温度应力进行分析研究,并提出通过合理的结构布置和使用新型的后浇带钢箱(板)变形装置来降低混凝土楼板温度应力、防止楼板开裂的方法。
The temperature effect of super-long concrete floor is so obvious that the tensile stress will easily lead to extensively slab crack. The temperature stress distribution in the concrete floor of a super-long underground structure is analyzed with FEM method, and some proposals, including optimization of structural arragement and new type of joint which is named as steel box deformation equipment, are raised.
