高层建筑平面刚体位移全天候摄像测量方法研究

Study on All-weather Camera Measurement Method of Plan Rigid Body Displacement in Tall Buildings

随着社会的进步,在现实生活中的高层建筑数目日益增多,它们为人们提供了更舒适的生活,扩大了生存空间,但与此同时它们的建成后期安全问题也成为人们讨论的焦点,不得不提上日程。目前已有的对高层建筑的观测方法大都以人工方法为主,而且由于高层及超高层建筑高度的原因,很多测量仪器无法实施监测,而对高层结构的动态变形实时测量更是现有测量设备和技术难以解决的问题。采用高精度工业级数字摄像仪进行全天候长期观测高层建筑动态位移,并综合分析试验现场人为活动、温度、光照、风力等外界因素,探索研究出更合理的测量方法,为日后相关技术在工程上的应用与实践提供相关方法。

With the progress of society,the number of tall buildings in real life is increasing day by day.They provide people with a more comfortable life and expand the living space.But at the same time,the safety problem in the later stage of their construction has become the focus and has to be put on the agenda.At present,the existing observation methods for tall buildings are mostly based on artificial methods,and due to the height of tall buildings and super tall buildings,many measuring instruments can not be monitored,and the real-time measurement of dynamic deformation of tall structures is a problem that is difficult to solve with the existing measuring equipment and technology.In this project,high-precision industrial-grade digital camera is used to observe the dynamic displacement of buildings for a long period of time,and external factors such as human activities,temperature,light and wind force on the experimental site are comprehensively analyzed to explore and study a more reasonable measurement method,so as to provide relevant methods for the application and practice of relevant technologies in engineering in the future.
