摘要

高精度三维重建技术在古建筑榫卯结构抗震性能分析中展现出独特优势。通过数字化采集与精细建模，可完整还原榫卯节点几何细节与连接方式，为后续力学模拟提供高可靠性数据支撑。在地震工况下，榫卯结构的受力模式与能量耗散机制可通过虚拟仿真得到量化分析，从而揭示其抗震特征与破坏路径。该方法不仅突破了传统实验难以实现的尺寸和重复性限制，也为复杂结构的多维参数研究提供便利。研究结果表明，结合三维重建与有限元分析能够更精准地评估榫卯节点的非线性响应，提升古建筑保护与加固设计的科学性。

Abstract

High-precision 3D reconstruction technology demonstrates unique advantages in seismic performance analysis of ancient architectural mortise-and-tenon structures. Through digital acquisition and detailed modeling, it enables comprehensive restoration of geometric details and connection methods at mortise-and-tenon joints, providing highly reliable data support for subsequent mechanical simulations. Under earthquake conditions, the force modes and energy dissipation mechanisms of mortise-and-tenon structures can be quantitatively analyzed through virtual simulations, thereby revealing their seismic characteristics and failure paths. This method not only overcomes the limitations of traditional experiments in terms of scale and repeatability but also facilitates multidimensional parameter studies for complex structures. Research findings indicate that combining 3D reconstruction with finite element analysis can more accurately evaluate nonlinear responses at mortise-and-tenon joints, enhancing the scientific rigor of ancient building conservation and reinforcement design.
