摘　　要：目前,采空区上方的地表沉降变形监测主要采用人工水准仪测量,该方法效率低、成本高、周期长,且无法实现自动化实时监测。为解决上述问题,引入静力水准自动化监测技术,在分析静力水准自动化监测工作原理及监测系统构成的基础上,对其可靠性、误差来源及消除方法进行了深入探讨,最后结合条带采空区上方地表监测实例从监测方案、测点布置、数据分析等多个角度进行了系统研究。研究结果表明:该技术能够满足条带采空区上方地表沉降变形自动化监测的要求,可为相关监测工作提供技术支撑。At present,the surface settlement and deformation monitoring above the goaf is mainly measured by artificial level.This method has the advantages of low efficiency,high cost,long cycle,and can not realize automatic real-time monitoring.In order to solve the above problems,the static leveling automatic monitoring technology is introduced.Based on the analysis of the working principle and composition of the static leveling automatic monitoring system,its reliability,error sources and elimination methods are deeply discussed.Finally,combined with the ground surface monitoring example above the strip goaf,the system is studied from the perspectives of monitoring scheme,measuring point layout,data analysis and so on.The results show that this technology can meet the requirements of automatic monitoring of surface settlement and deformation above strip goaf,and can provide technical support for relevant monitoring work.
