摘　　要：以某典型浅埋矿区为工程背景,采用数值模拟方法研究了在盾构法施工情况下斜井井筒的围岩变形破坏规律。在盾构法掘进过程中,井筒围岩变形由于各段支护强度不同出现"台阶"状分布,在实际施工中应注意加强不同阶段的围岩变形监测,防止围岩破坏情况出现。研究得到了盾构施工斜井围岩变形的一般规律,为相似条件下的斜井支护技术提供了参考。Taking a typical shallow mining area as an engineering background, the deformation and failure law of surrounding rock under shield construction of inclined shaft is discussed by numerical simulation. In the process of shield tunneling, the deformation of shaft surrounding rock has stepped distribution because of the different supporting strength of each section. In actual construction, should pay attention to monitoring the deformation of surrounding rocks at different stages, so as to prevent the occurrence of surrounding rock failure. The general rule of the deformation of the surrounding rock of the inclined shaft in the shield construction is obtained, which provides a reference for the inclined shaft supporting technology under similar conditions.
