摘　　要：针对城市高耸建筑物倾斜观测作业时间长、信息量少的问题,将三维激光扫描技术应用到城市高耸建筑物变形监测领域,探讨对无观测标志、不可或不便攀登的城市高耸建筑物进行倾斜观测的施测方法。以龙柱为例,制定了可行的测量方案,并采用高斯曲面拟合算法对其表面进行拟合,精确计算出龙柱的倾斜量,且与全站仪倾斜观测结果进行对比。结果表明,该方法可以快速、全面的获取观测对象的整体信息,且能够满足高耸建筑物倾斜观测的精度要求。According to time consuming and less information in the tilt observation of tall buildings, this paper applies three-dimensional laser scanning technology to the field of deformation monitoring, dis- cussing the method of tilt observation tall buildings with no observation signs, unable to climb build- ings. Taking the dragon post as an example, the feasible measurement scheme is worked out, and the sur- face of the dragon post is fitted by using the Gauss surface fitting algorithm, calculate the tilt of the drag- on post. Compared with the method of total station, results show that this method can obtain the whole information of the observation object quickly and comprehensively, and can satisfy the accuracy require- ment of the tall building tilt observation.
