Cave temples, as an important type of immovable cultural heritage, are the concentrated manifestation of China's brilliant ancient civilization and a historical testimony of exchanges and mutual understanding between Chinese civilization and other ancient civilizations, but they have been subjected to long-term water erosion and damage, with fissure seepage having a particularly serious impact. For the detection, prevention and control technology of fissure seepage in cave temples in the humid areas of southern China, this paper systematically combs through the research progress in fissure seepage detection technology, fissure seepage disease mechanism, fissure seepage management and control technology, monitoring and assessment technology of management effect, and the demonstration and application of the management technology, with a view to providing references to the relevant researches and work.
