Application of Ground-Penetrating Radar with the Logging Data Constraint in the Detection of Fractured Rock Mass in Dazu Rock Carvings, Chongqing, China
Ground-penetrating radar (GPR) with logging data constraint significantly enhances the accuracy of detecting rock mass fissures in grottoes, addressing limitations of conventional GPR methods. By integrating borehole televiewer and logging data, researchers calibrated electromagnetic wave velocity, enabling precise depth calculations for anomalies in GPR profiles. This approach reduced false positives caused by interference, providing reliable location information for fissures, fracture zones, and weak interlayers in the Baodingshan Scenic Area of Dazu Rock Carvings, Chongqing, China. The study demonstrates that combining GPR with logging data mitigates uncertainty in geologic interpretations, offering a novel technical solution for the preservation and restoration of grotto relics.

The simulation of groundwater flow in fractured medium of Dazu Rock Carvings with a DFN model
A numerical simulation of groundwater flow in the fractured medium of Dazu Rock Carvings reveals distinct hydraulic behaviors in structural fractures and weak intercalations. Using DFNworks software, researchers analyzed caves 176, 177, and 180 in Beishan, identifying that structural fractures exhibit significantly higher hydraulic head and velocity compared to weak intercalations. Under steady seepage conditions, the flow rates were measured at 1.74×10⁻² m³/s for cave 176, 2.3×10⁻² m³/s for cave 177, and 0.71×10⁻² m³/s for cave 180. This study provides critical insights into the hydrogeological conditions affecting the site's water seepage diseases, which were classified based on occurrence frequency, location, and preservation status.

Salt weathering of sandstone under dehydration and moisture absorption cycles: An experimental study on the sandstone from Dazu rock carvings
Salt weathering significantly accelerates the deterioration of sandstone, particularly when sodium sulfate undergoes phase transitions between thenardite and mirabilite during dehydration and moisture absorption cycles. Laboratory experiments on sandstone from Dazu Rock Carvings (DRC) in China revealed that high salt concentrations (2.4 mol/L) lead to severe disintegration, while moderate levels (1.5 mol/L) cause flaking and surface salt accumulation. Damage is more pronounced under dehydration conditions, where thenardite formation exerts greater stress than mirabilite during moisture absorption. Salt migration and clay mineral distribution further influence deterioration patterns, mirroring natural weathering observed in the field. Critically, no damage occurs when salt content remains below 0.67%, offering a threshold for conservation strategies. These findings provide actionable insights for preserving DRC.

Degradation of Emerald Green: Scientific Studies on Multi-polychrome Vairocana Statue in Dazu Rock Carvings, Chongqing, China
Researchers have identified the degradation products of emerald green and cerussite, two historically used pigments, in the multi-polychrome Vairocana Statue at Dazu Rock Carvings. The study reveals that lavendulan (NaCaCu5(AsO4)4Cl·5H2O) and mimetite (Pb5(AsO4)3Cl) form through complex chemical processes involving the degradation of emerald green (Cu(C2H3O2)2·3Cu(AsO2)2) and cerussite (PbCO3), oxidation of arsenite, migration of arsenate, and precipitation reactions influenced by environmental conditions. The analysis of paint cross-sections using optical microscopy, Raman spectroscopy, SEM–EDS, and mapping also indicates that the statue's paintings were executed at least four times, with the most recent layer possibly dating to after 1850s. This finding highlights the importance of understanding pigment degradation in complex environments for heritage conservation.

Virtual Inpainting for Dazu Rock Carvings Based on a Sample Dataset
A novel semi-automatic exemplar-based inpainting framework leverages a sample dataset to effectively restore severely damaged art images, such as the Dazu Rock Carvings, where minimal prior information is available. The approach extends the search space for candidate patches beyond the known region of the original image, addressing challenges in traditional inpainting methods. By integrating deep convolutional networks for reference image selection and melding algorithms for sample image creation, this method reduces complexity while avoiding duplication issues in art restoration. Poisson blending further enhances visual harmony between reconstructed fragments and existing regions. Applied to Buddhist face images from Dazu, the framework demonstrates its potential as a reference for both actual artificial inpainting and virtual reality presentations.
