摘　　要：针对水平位移监测无法分析整体移动趋势的问题,该文提出了一种基于趋势一致性矩阵的水平位移监测数据处理方法,该方法通过构造趋势向量和一致性矩阵,计算出判断矩阵,根据判断矩阵元素值分析监测点的位移趋势。同时,提出了基于向量的水平位移向量图,以分析位移的变化情况。实验证明,该文提出的数据处理方法能有效分析出建筑物水平位移趋势,且水平位移向量图具有可视化程度高、动态效果好的特点。此外,该方法还可定性定量反映监测点的水平位移轨迹,分析出任意两期位移变化状况。In view of the problem that horizontal displacement monitoring can not analyze the overall movement trend,this paper presented a horizontal displacement data processing method based on trend consistency matrix,which determined the displacement trend by constructing trend vector and consistency matrix,calculating the judgment matrix and analyzing the matrix element.Meanwhile,a horizontal displacement vector graph was put forward based on vector in order to analyze the horizontal displacement variation.The experimental results showed that the proposed data processing method could effectively analyze the horizontal displacement movement trend of a building,and the horizontal displacement vector graph had the characteristics of high visualization and good dynamic effect.In addition,it could also qualitatively and quantitatively reflect the horizontal displacement trajectory of the observation points,and analyze the displacement changes of any two periods.
