摘　　要：基于采空区地表移动机理及破坏形式,从理论角度分析采空区地表移动对上覆油气管道变形影响。以此为基础,将某油气管道拟建工程作为研究案例,采用数值仿真模拟方法分析不同煤层倾角、不同煤层埋深两个角度分析采空区地表移动对上覆油气管道的影响。根据研究结果可知,采空区地表移动参数变化对上覆油气管道的影响较为显著,在上覆油气管道建设中应重点考虑采空区地表移动的影响。Based on the surface movement mechanism and failure form of goaf area,the influence of surface movement in goaf on the deformation of overlying oil and gas pipeline is analyzed from a theoretical perspective.Based on this,the proposed construction project of an oil and gas pipeline is taken as a research case,and the numerical simulation method is used to analyze the influence of surface movement on the overlying oil and gas pipeline from two angles:different coal seam inclination angles and different coal seam burial depths.According to the research results,the influence of surface movement parameters in the goaf on the overlying oil and gas pipeline is significant,and the influence of surface movement in the goaf should be considered in the construction of the overlying oil and gas pipeline.
