| 摘 要： | 在钢筋混凝土井壁结构破裂的弹塑性理论基础上，利用大型通用结构分析软件ANSYS进行了深厚表土中井壁结构的弹塑性数值模拟计算，得到井壁破裂的过程、井壁内部应力应变的动态变化规律，探讨了井壁结构与深厚围岩（土）耦合作用机理，为深厚表土层中井壁破裂的防治提供了理论依据。

| Abstract: | Based on the elasto plasticity theory of reinforced concrete shaft lining structure fracture,the numerical analyses of shaft lining structure in thick alluvium are carried out by using the large current structure analysis software ANSYS. The cracking process and changing law of stress and strain inside the shaft lining are obtained. The coupling mechanism between reinforced concrete shaft lining and thick surrounding rock(soil) is explored, which provides theoretical foundation for the preventing and curing techniques of shaft lining fracture. |
