从建筑物荷载引发地面沉降的机理模型出发,综合考虑建筑物产生的附加应力以及地基土壤压缩性质对沉降量的影响,构建了改进克里金插值模型。通过实际应用证明,使用改进克里金插值模型进行城市地面沉降空间趋势面模拟和计算,能够准确清晰地反映沉降变形的大小和趋势,从而为地面沉降的空间建模与可视化分析、总结建筑物荷载作用下城市地面沉降的变形规律奠定基础。
In this paper, we propose the improved Kriging interpolation model which considers the in- fluence of additional stress and soil compression properties, based on ground subsidence mechanism induced by building load. It is illustrated that this method can be effectively used in spatial trend sur- face imitation and calculation. The results accurately and clearly show subsidence deformation values and trends. So, this research provides a scientific basis for land subsidence spatial modeling, visual a- nalysis and summary of subsidence discipline induced by building load in urban areas.
