Abstract. In the case study of Guanghua Pavilion [光化楼] located in Jiayuguan [嘉峪关] City, Gansu province in China, the 3D laser scanning technology and leveling technology are used to analyze overall tilt, columns tilt and uneven settlement of the pavilion. It is found that Guanghua Pavilion [光化楼] tilted to the southeast; most of the columns from the first floor to the third floor tilted to the northeast and east directions, and all the tilted distance of the columns is within 100 mm.; a certain amount of uneven settlement happened on Guanghua Pavilion [光化楼], in which the east side sinks more obviously. In the process of analyzing the influencing factors of deformation, numerical wind tunnel simulation and Midas Gen modeling methods are used. It is concluded that the external wind load is the main cause of Jiayuguan [嘉峪关] pavilions’ deformation.
