Abstract: This paper compares and analyzes the horizontal deformation law of tunnel surrounding rock under different excavation directions and the influence of soil and rock interface inclination angle on the horizontal deformation of tunnel surrounding rock.The results show that the horizontal deformation laws of tunnel surrounding rock under different excavation directions are similar and the horizontal deformation of the surrounding rock at the working face decreases with the increase of the dip angle of the earth-rock interface,and the decreasing amplitude gradually increases.The results of the study will provide important references for tunnel excavation construction under the geological conditions of soil and rock boundary.

Key words: tunnel, soil and rock interface, excavation direction, tunnel surrounding rock deformation

摘要： 文中对比分析了不同掘进方向下的隧道围岩水平变形规律以及土石界面倾角对隧道围岩水平变形的影响,结果显示:不同掘进方向下的隧道围岩水平变形规律相近;掌子面处围岩水平变形量随着土石界面倾角的增大而减小,且其减小幅度逐渐增加。该结果将对土石交界地质条件下隧道开挖建设提供重要参考。
