摘　　要：将彼此关联的多个变形监测点纳入整体建模,将单点的变形分析扩展到空间多点的整体变形分析,采用非等间距等距化处理的改进方法,建立了基于非等间距的多点变形预测模型。本文通过实例分析与对比,验证了非等间距多点变形预测模型的可行性和有效性,是一种非线性时空整体变形分析与预测的新方法。Taking consideration of the integrity modeling with correlative multiple deformation points,this paper extends the single point deformation analysis into spatial multi-point integrity analysis and presents a non-equidistant multi-point modeling by improving equispacing processing for the non-equidistant series.The real practical analysis and comparative results indicate that the non-equidistant multi-point prediction model is feasible and effective,which is a new nonlinear approach to the integrated deformation analysis and prediction in time and space domain.
