Study on the Dynamics Characteristics of Elastic Wave of Weathered Zone in Longmen Grottoes

Research on the Longmen Grottoes reveals that elastic wave velocity and attenuation coefficients effectively distinguish between good and poor rockmass quality, with thresholds of 0.01 for P-waves and 0.1 for S-waves serving as critical indicators. The study found that while surrounding rocks exhibit high elasticity, suggesting a solid structure, their anisotropy is pronounced, indicating well-developed structural planes. These dynamics are crucial for the preservation of historical relics at the site.
