| 摘 要： | 本文主要探讨的是深厚表土层中立井井筒受竖向压力及水平力作用而失稳,形成纵向弯曲(内鼓),由此产生的张、剪裂隙随弯曲发展和加剧,在其相互作用下致使井筒破裂,并论证这一看法的可能性。

| Abstract: | The paper mainly discusses the longitudinal flexion (convex to inside) resulting from thedestabilized shaft walls caused by vertical and horizontal pressures in deep and thick overburdens. It also proves that the consequent tension and shearing fractures become greater and greater so that the break comes with their interplays. |
