建筑物加载过程中高精度变形监测研究

Research on High Precision Deformation Monitoring of Building during Loading

采用TM30测量机器人对图书加载过程中笔者所在院校图书馆进行变形监测,对变形观测数据进行严密平差,获取监测结果;进而根据监测结果绘制变形等值线,表达出各个方向的变形量,直观表达危险变形区域;最后获取建筑物加载过程中的变形监测规律。在图书加载初期,南北方向变形呈不稳定S型,而东西方向变形从初期开始变形趋于围绕图书加载位置。建筑物长、宽对建筑物稳定有影响,在建筑物加载位置需要增加承重及在外围采取防护措施。该研究对建筑设计有实际意义。

In this paper, the TM30 goeorobot is used to monitor the defiwmation of Beijing Polytethnic College library during the loading of books. The monitoring data are adjusted strictly to obtain the monitoring resuhs. What is more, according to the monitoring resuhs, the deformation contour line is plotted and the deformation in each direction is displayed, therefore, the dangerous defiurmation area is visually expressed, Finally, the deformation monitoring law during the buihling loading is obtained. At the early stage of loading, the defiwmation of the north-sot,th direction is unstable as ＂S＂ , while the deformation of the east-west direction teuds to be around the loading position of the book. From what has been mentioned above, we ean come to the conclusion that the length and widlh of the building have an impact on the stability of the building, and it is neeessary to increase the building load and take protective measures on the periphery, where the building needs to be loaded. The research has practical implications for architectural design.
