This article systematically explores the research methods of high-precision 3D mapping and mechanical performance restoration of traditional textile dome architecture,aiming to achieve the protection and structural safety assessment of cultural heritage through digital technology and modern mechanical analysis methods.The study uses 3D mapping techniques such as laser scanning and photogrammetry to accurately obtain geometric data of the dome and construct millimeter level 3D models.Combined with finite element analysis,it simulates its mechanical response under different loads.Case analysis shows that 3D mapping technology can effectively identify structural damage and deformation,and the mechanical performance restoration model reveals the design wisdom of traditional domes in dispersing stress through geometric shape optimization.The study further validated the accuracy of numerical simulation and proposed improving structural stability by adjusting fabric tension distribution.This study provides scientific basis for the protection and restoration of traditional textile dome architecture,and promotes the deep integration of cultural heritage and modern engineering technology.
