摘要

Water damage is one of the primary threats to limestone grottoes. This study proposes the installation of rainproof cowls above the heritage site, which not only shield against rainfall but also enhance the evaporation of seepage water within crevices. Research findings indicate that after the installation of the cowls, the wind speed in the crevices of the cliff increased from 0 to 3.8 m/s, while the evaporation time of seepage water decreased from the original 3–4 days to just 53 min. Additionally, the wind speed inside the grottoes rose from 0 to 0.1 m/s. This study represents an innovative interdisciplinary approach to mitigating water seepage damage, holding positive significance for the preservation of human civilization and cultural heritage.
