摘要
变形监测在保障工程安全、建筑物的监测以及地质结构分析等方面扮演着重要的角色。尤其是在城市发展中,地面沉降更是非常突出的问题。本文针对目前通过精密水准或GNSS进行地面沉降监测存在监测点位离散,且分布不均的问题,提出采用克里金插值模型进行沉降量内插的设想,并通过北京局部沉降监测实测数据,对上述差值模型进行了验证和精度分析。结果表明克里金插值模型用于地面沉降监测数据内插是可行的。
Deformation monitoring plays an important role in ensuring project safety,building monitoring,and geological structure analysis.Especially in urban development,land subsidence is a very prominent problem.In view of the current problems of discrete monitoring points and uneven distribution of ground subsidence monitoring by precision level or GNSS,this paper proposes the assumption of Kriging interpolation model for interpolation of settlement amount,and the measured data of local settlement monitoring in Beijing.The above difference model has been verified and precision analyzed.The Kriging interpolation model is considered feasible for interpolation of ground subsidence monitoring data.
