The ancient underground cavern of Longyou has a history of more than 2,000 years, and it exhibits a considerable value in archeology, history, science, and culture; therefore, its protection is of considerable significance. Investigating the development mechanism of vault cracks is an important part of the protection work. Most previous studies have been conducted from a single perspective. For an in-depth study, a multi-factor approach is used to conduct comprehensive research based on mechanical analysis and monitoring analysis. The analysis shows that the vault cracks continue to expand and uneven settlement of vault increases gradually. Theoretical analysis and monitoring exhibit similar trends, which indicates that the vault is considerably damaged; therefore, a reinforced support technology is necessary. In this study, the Building Information Modeling (BIM) technology is considered for application to an ancient underground cavern. It has the potential to provide new ideas and visual materials to investigate and conserve the ancient underground cavern of Longyou. In addition, it would promote the wider application of the BIM technology in geotechnical engineering.
