| 摘 要： | 对某巨型钢衬钢筋混凝土联合承载蜗壳，采用三维非线性有限元法计算结果表明：当弹性垫层６ｃｍ和垫层材料弹模为２ＭＰａ时，原设计的钢衬为６ｃｍ偏厚，钢衬与座环连接部位应力集中较大；给出了随内水压力增加，埚壳外包混凝土塑性变形和开裂区的发展过程。对上述问题提出了改进措施建议。

| Abstract: | The three dimensional nonliear element method is used to calculate compositestructure stress of huge steel scroll case and outer covering reinforced concrete.The result ofcalculating indicates:When the thickness of elastic pad is 6 cm and its elastic modulus is 2-20MPa,the max.stress of steel scroll case is smaller than project strength.It is suggested that thethickness of steel scroll case be reduced or the low strength steel material be selected. |
