本文针对目前国内外普遍关注的地下洞室掘进面的空间效应进行了探讨。利用三维弹性和弹塑性有限元法分析了泊松比v、侧压力系数λ、围岩的粘聚力C、内摩擦角φ、洞形及尺寸变化等多种因素对掘进面前后释放位移的影响,掌握了在不同情况下掘进面附近位移释放规律及掘进面空间效应的影响范围。 This paper discusses the spatial effects of the underground caverns that are generally concerned at home and abroad. The three-dimensional elastic and elastic-plastic finite element method was used to analyze the Poisson’s ratio v, the lateral pressure coefficient λ, the cohesive force C of the surrounding rock, the internal friction angle φ, the shape of the hole and the dimensional change, and so on. Influence, mastered the displacement and release rules near the driving surface and the influence of the spatial effect of the driving surface under different conditions.
