| 摘 要： | 本文选用了正交各向异性体的本构关系和适应于砼井壁特性的强度准则,编制了对砼井壁进行数值分析的非线性有限元程序。并采用此程序分别对砼井壁在承受均布荷载和非均布荷载条件下的应力分布和极限承载能力进行了计算分析,其计算结果与实验结果得到了良好的吻合。

| Abstract: | By adopting the orthogonal inhomogeneous constitutive model and the strength criterion suiting for the concrete shaftlining behaviours, a nonlinear finite element program is worked out for the numerical analysis of concrete shaftlining. It is applied to calculate and analyze the stress and the ultimate load-bearing capacity of concrete shaftlinings subjected uniform loads or non-Uniform loads. The results are well consistent with that from the experi - ments |
