基于合向量的水平位移趋势一致性分析

Trend Analysis of Horizontal Displacement Based on Resultant Vector

当前水平位移分析仅从数值判断其对建筑物造成的损害,而对建筑物整体位移是否具有一致性缺乏分析与推理,针对这种现状,本文提出了一种基于合向量的水平位移整体趋势判断法。该方法通过构造一致性矩阵,计算监测点各期单点合向量与总合向量,从而判定建筑物是否存在一致性位移趋势。水平位移监测实验发现,该方法能有效地反映建筑物整体位移情况,且具有较好的可视化效果,能动态地描述各点位移轨迹及总体位移趋势,是一种兼有高效率与高可视化效果的水平位移监测数据分析方法。

At present,the horizontal displacement analysis can only judge the damage to buildings caused by its numerical value,however,there is lack of analysis and reasoning about the overall displacement of the building. In this situation,we put forward a method to determine the overall trend of horizontal displacement,which judge if it exists consistency displacement of the building by constructing consistency matrix and calculating single point resultant vector in each period and sum resultant vector. Experiment found that this method can effectively reflect the overall situation of building displacement,and it has a good visual effect,and it can also describe the displacement trajectory and overall displacement trend,it is a high efficiency and high visual effect analysis method for horizontal displacement monitoring data.
