Three‐Dimensional Numerical Modeling and Roof Deformation Analysis of Yuanjue Cave Based on Point Cloud Data

A high-precision three-dimensional numerical model of Yuanjue Cave, a core site within the Dazu Stone Carvings World Heritage Site, reveals critical deformation patterns under static loads that threaten its structural stability. The study leverages advanced laser point cloud scanning, geophysical prospecting, and indoor testing to construct an accurate digital twin of the cave's geometry, geology, and physical properties. By simulating roof behavior using FLAC3D finite difference analysis, researchers validated the model against on-site measurements, demonstrating its reliability for predictive conservation efforts. This approach provides essential parameters for proactive measures to prevent collapse, safeguarding this irreplaceable cultural treasure from irreversible damage.
