摘　　要：通过对某超长地下室结构的环境温度作用进行计算,并采用有限元方法对外墙不贴与贴XPS板两种情况下地下室的温度应力进行分析,研究XPS板在超长地下室混凝土结构温度裂缝控制中的作用。分析结果表明,外贴XPS板可有效地控制超长地下室的环境温度作用,从而降低结构的温度应力,对温度裂缝控制的效果显著。In this paper, the environmental temperature effect of an over-length basement structure is calculated. The temperature stress of the basement in setting and not setting the XPS is analyzed by the finite element method. The effect of XPS in temperature crack control of an over-length basement concrete structure is studied. The results show that the application of XPS can control the environmental temperature effect of the over-length basement effectively, and the temperature stress is reduced. There by the temperature crack is controlled well.
