摘要
采用MIDAS-Gen、ANSYS 2种有限元软件分别对某圆形煤场进行结构计算,共选用全场堆煤荷载、半场堆煤荷载及整体升温荷载、温度梯度荷载4种荷载工况。对计算结果进行分析,得出以下结论:2种软件模拟结果基本一致;温度作用对挡煤墙影响显著;梁板单元模拟有所欠缺,可能是因为其刚度小;顶部环梁可形成环箍作用;半场堆煤工况下,在堆煤和不堆煤分界处挡煤墙变形严重。以上结论可为类似工程设计提供依据。
Two kinds of finite element software MIDAS-Gen and ANSYS are used to calculate the structure of a circular coal yard.Full-field coal-piling load,half-field coalpiling load,whole heating load and temperature gradient load are selected.Through the analysis of the calculation results,the following conclusions are drawn:the results of the two software simulation are basically the same;the effect of temperature on the retaining wall is remarkable;the beam and slab element simulation is deficient,possibly because of its smaller stiffness;the top ring beam can form the hoop effect;under the condition of half-field coal-piling,the retaining wall at the boundary between coal-piling and non-coalpiling is severely deformed.The above conclusions can provide a basis for engineering design.
