摘　　要：在建筑施工质量监测中,利用建筑整体的频率和振动情况判断结构是否存在损伤和安全隐患,但是对结构的质量监测效果不好,为此,论文提出一种基于粒子群优化聚类提出建筑施工质量监测技术。根据建筑结构设计标高,从方差最大的维度开始分割建筑构件数据点,将沿z轴方向分布的数据点判定为柱体结构,沿x轴和y轴方向分布的数据点判定为墙面结构。对横向、纵向的防护栏杆和钢筋等工程对象建立不同的图元类别,使用索引值判断边界框是否相交,在施工时需要注意两个连接构件的牢固程度。使用固有频率和结构振型函数作为适应度函数,利用粒子群优化聚类对建筑的局部结构进行迭代寻优,完成质量监测。将此监测技术应用于实际建筑施工工程中,结果表明,该建筑处于正常施工状态,在荷载作用下不会发生建筑振动和结构破坏,满足建筑工程规范,具有较高的施工质量。In the quality monitoring of building construction,the overall frequency and vibration of the building are used to judge whether the structure has damage and potential safety hazards,but the quality monitoring effect of the structure is not good.Therefore,this paper proposes a clustering method based on particle swarm optimization.Construction quality monitoring technology.According to the design elevation of the building structure,the data points of the building components are divided from the dimension with the largest variance,and the data points distributed along the z-axis direction are determined as the column structure,and the data points distributed along the x-axis and y-axis directions are determined as the wall structure.Establish different primitive categories for engineering objects such as horizontal and vertical protective railings and steel bars,and use the index value to determine whether the bounding boxes intersect.During construction,it is necessary to pay attention to the firmness of the two connecting components.Using the natural frequency and the structural mode shape function as the fitness function,the particle swarm optimization clustering is used to iteratively optimize the local structure of the building to complete the quality monitoring.This monitoring technology is applied to the actual building construction project,and the results show that the building is in a normal construction state,and no building vibration and structural damage will occur under the load,which meets the construction engineering specifications and has high construction quality.
