| 摘 要： | 针对白居寺吉祥多门塔变形情况复杂,分析难度大等因素,研究采用了地面激光雷达技术获取和分析其变形情况的方法.整体分析是对统一坐标系后两期模型沿着某个方向剖切,得到反映整体变形情况的剖切线;局部分析是通过计算点到参考面的距离,分析得到详细的变形情况,根据建筑的特点,采用整体和局部相结合的分析方法.该方法切实可行,非常适用于西藏白居寺这种复杂建筑的变形分析,能够获得准确地变形数据,为以后的修缮工作提供依据.

| Abstract: | For the problem of complex deformation condition and difficult analysis of multi-door Chorten of Baiju Temple,a method of getting and analyzing deformation condition with Terrestrial LIDAR technology is researched in this paper.Two models from different periods with same coordinate system are sliced along a certain direction to get the section line in the overall analysis.Point to the reference plane distance is calculated in local analysis.According to the build’s characteristic,a combination of global and local analysis is adopted.This method is practical and very suitable for the construction of complex multi-door Chorten deformation analysis in Tibet.The accurate deformation data got from the analysis can be provided for the basis of later repair work. |
