摘　　要：建筑物倾斜监测是评估建筑物结构安全性和管理风险的重要手段。本研究选取四川建筑职业技术学院多栋混凝土建筑和钢结构建筑为研究对象,结合无人机航测技术和全站仪实测方法,分析两类建筑在不同高度区间的倾斜特性及变化规律。研究发现,混凝土建筑相对于钢结构建筑具有更强的抗倾斜性,且与建筑物高度相关。此外,通过对航测提取的倾斜度与全站仪实测值的对比分析,混凝土建筑和钢结构建筑的拟合精度R~2分别达到0.90和0.94,证明无人机航测技术在建筑物倾斜监测中的高精度和可行性。该方法为大规模建筑物倾斜监测和动态评估提供了高效且可靠的解决方案,为建筑物结构安全管理与维护提供了科学依据。Building inclination monitoring is a critical approach for assessing structural safety and managing risks in buildings.This study investigates multiple concrete and steel structure buildings at Sichuan College of Architectural Technology,utilizing UAV photogrammetry and total station measurements to analyze the inclination characteristics and variations of these two building types across different height ranges.The results reveal that concrete buildings exhibit greater resistance to inclination compared to steel structures,with inclination closely associated with building height.Additionally,a comparison between inclination values extracted from UAV photogrammetry and those measured by total stations demonstrates high fitting accuracy,with R 2=0.90 for concrete buildings and R 2=0.94 for steel structures.These findings confirm the high precision and feasibility of UAV photogrammetry in building inclination monitoring.This method offers an efficient and reliable solution for large-scale building inclination monitoring and dynamic assessment,providing a scientific basis for structural safety management and mainten ance.
