摘要
建立了深厚表土中钢筋混凝土井壁结构破裂的弹塑性理论，利用大型通用结构分析软件ＡＮＳＹＳ进行了井壁结构的弹塑性数值模拟计算，得到在水平地压、井壁重力以及随时间不断增大的竖直附加力的共同作用下井壁结构内部应力、应变的动态变化过程，探讨了深厚表土中井壁结构破裂的力学机理以及裂缝出现的位置和扩展过程，为井壁破裂的治理和预防提供了理论依据．
The elasto plasticity theory of reinforced concrete shaft lining structure fracture in thick alluvium is established. By using the large current structure analysis software ANSYS, the elasto plasticity numerical analyses of shaft lining structure are carried out. The changing process of stress and strain inside the shaft lining acted by the horizontal soil and water pressure,gravity and the additional vertical force is obtained. The mechanical mechanism and process of shaft lining fracture,the location and developing process of cracking are explored,which provide theoretical foundation for the preventing and curing techniques of shaft lining fracture.
