Research on the Three-Dimensional Numerical Model and Characteristics of Rock Materials of Stone Cultural Relics

Abstract:

For further understanding the mechanical characteristics and structural stability of cliff stone relics noumenon, and studying the damage and deterioration characteristics under weathering, the basic mechanical tests and non-destructive exploration research of granite rocks in Tieshan Cliff rock relics were carried out combined with engineering project. The basic mechanical parameters of rock and the fracture appearance were obtained through experiments, the three-dimensional numerical model was established according to the laser scanning result, and the structural plane and fracture development of rock mass were analyzed based on the three-dimensional model, so as to study the damage and failure mechanism of granite rock that of cliff stone relics. The results indicate that the damage strength and fragmentation degree of rock are obviously different under different conditions between weathered rock and fresh rock. The internal structure of weathered rock gradually develops from lamellar growth to porous structure. Fracture development of rock mass is an important factor affecting the stability of cliff stone relics noumenon. The research can provide scientific basis for the conservation and restoration work of cliff stone carving.
