Study on Deformation of Ancient Pagoda Based on Lagrange Multiplier Method

Lihua Qi, Dongqiu Xing, Rui Wang, Jing Zhao


Start The deformation problem of ancient pagoda was solved by using of the least square method and Lagrange multiplier method in this paper. According to the observation data, through modelling and analysis, a general method for solving the coordinates of the center points of each layer of ancient pagoda was given. Then, the model and analysis of ancient pagoda were carried out from three aspects of overall tilt, bending and twisting, and the quantitative calculation method of tilt, bending and twisting of ancient pagoda is obtained.
