| 摘 要： | 利用ANSYS有限元软件，并考虑钢壳-垫层、钢壳-混凝土之间的摩擦接触条件，建立钢蜗壳及其外围混凝土的局域三维应力计算，来分析垫层的弹模、厚度、泊松比等参数对钢壳及其外混凝土受力状况的影响，得到一些参考价值参数成果。

| Abstract: | Using the software ANSYS and taking into account of the friction of the cushion with the spiral case and with the surrounding concrete,a local 3-D model is established and applied to calculate the stresses in the steel sprial case and in the surrounding concrete,and to analyze the influences of the cushion parameters(elastic modulus,thickness,Poisson's ratio) on the stress state.Some useful conclusions are reached. |
