摘　　要：在前人工作基础上，初步研究建立了利用多种地形变资料联合求解地壳应变连续分布的方法途径和数学模型。包括利用多种地形变观测资料整体解算测区分单元的应变张量的最小二乘平差模型，以及借助最小二乘配置进行应变空间连续分布估计的方法。并给出了对临潼水平形变同监测资料的试算结果。In this paper, the mathematical model and means that can jointly solve the crustal strain continuous distribution by using varied observational data of crustal deformation are preliminarily studied and formed, on the basis of previous researches including the least square adjustment model of integrally solving strain tensor of parting element in monitoring region by using varied observational data of crustal deformation, and method of estimating continuous space distribution of strain with the aid of least square collocation. Moreover, the calculated result of monitoring data is given for horizontal deformation monitoring net in Lintong region.
