预应力混凝土箱形倒虹吸管温度应力的有限元分析

Prestressed concrete box inverted siphon tube temperature stress finite element analysis

运用ANSYS有限元热—结构耦合分析建立箱形倒虹吸管结构温度计算的模型,分析了温度应力对预应力混凝土箱形倒虹吸管的影响,得出当温度应力过大时,会造成倒虹吸管表面产生裂缝的结论,该成果对类似工程温度应力分析和温控具有一定借鉴意义。

Using ANSYS finite element thermal-structural coupled analysis established model of box-shaped siphon tube structure about temperature calculation. Thermal stress analyzed effects of prestressed concrete box-shaped inverted siphon. When the temperature stress is too large, it will cause cracks in the surface of inverted siphon. The results has a certain reference of similar projects temperature stress analysis and the thermostat.
