摘　　要：随着监测技术的发展,传统二维图表已难以满足日益增长的结构安全监测需求。互联网与计算机三维可视化技术,使监测数据呈现出以多维度、更加真实与实时的形式进行展现的发展趋势。在此过程中,利用分布式监测进行结构整体变形计算,成为监测数据多维展示的关键。在结构力学柔度矩阵的基础上,提出广义柔度矩阵,建立了基于广义柔度矩阵的结构整体变形计算方法,并在上海音乐厅观众厅穹顶木屋架监测中进行了应用。该方法可为后续结构安全监测数据的三维可视化提供技术支撑。As monitoring technique advances,traditional 2D charts are becoming inadequate for meeting the increasing demands of structural safety monitoring.The integration of the Internet and computer-based 3D visualization technology enables monitoring data to be presented in a multi-dimensional,more realistic,and real-time manner.In this process,using distributed monitoring to calculate overall structural deformation becomes crucial for multi-dimensional data display.Based on the flexibility matrix of structural mechanics,a generalized flexibility matrix is proposed,and an overall structural deformation calculation method based on this matrix is established.This method is applied in the monitoring of the dome roof truss of the auditorium at the Shanghai Concert Hall,providing technical support for the 3D visualization of subsequent structural safety monitoring data.
