故宫博物院午门变形分析预测数据集
收藏资源简介：
本数据集来源于2024年9月至11月期间在中国故宫午门城楼开展的结构健康监测工作，旨在支撑古建筑长期保护与变形预测研究。监测系统基于全站仪、数字水准仪、传感器，对午门城楼多个关键位置进行定点监测，采集纵向、横向与垂直位移、高程变化、沉降、振动与倾斜等参数，时间采样频率为定期采集并传输至控制中心。空间精度达到毫米级，能够反映古建筑微小形变特征。为满足时间序列建模对等间隔数据的要求，研究通过等间隔提取方式构建数据集，并对原始数据中的少量缺失值采用线性插值方法进行填补，以保持数据的连续性与趋势性。基于监测数据与结构模型计算得出安全形变阈值区间，并开展未来10日变化趋势预测，为午门城楼结构安全评估与保护决策提供依据。该数据集具有较高再利用价值，可为其他古建筑结构监测与预测研究提供参考与数据支持，数据量为31.1MB。
This dataset originates from the structural health monitoring campaign carried out at the Meridian Gate (Wumen) of the Forbidden City in China from September to November 2024, aiming to support long-term conservation and deformation prediction studies of ancient Chinese architecture. The monitoring system, based on total stations, digital levels and various sensors, conducts fixed-point monitoring at multiple key positions of the Meridian Gate tower, collecting parameters including longitudinal, lateral and vertical displacements, elevation changes, settlement, vibration and inclination. The sampling is performed at regular intervals, and all collected data are transmitted to the central control center. The spatial accuracy reaches the millimeter level, enabling the capture of subtle deformation features of ancient architecture. To meet the requirement of equally-spaced data for time series modeling, this study constructed the dataset by extracting data at equal intervals, and filled the small number of missing values in the original data with linear interpolation to maintain data continuity and trend characteristics. Based on the monitoring data and structural model calculations, the safe deformation threshold range was determined, and a 10-day future variation trend prediction was conducted, providing a reliable basis for structural safety assessment and conservation decision-making of the Meridian Gate tower. This dataset boasts high reusability, and can provide reference and data support for other structural monitoring and prediction studies of ancient architecture, with a total data size of 31.1 MB.
