DEVELOPMENT STATUS AND PROSPECT OF ROCK MASS STABILITY MONITORING TECHNOLOGY IN GROTTOES TEMPLE
Most immovable cultural relics in grotto temples are built on slopes,with caves mainly excavated inside cliff bodies.However,due to the complex geological characteristics,structure,occurrence environment,and boundary conditions of grotto temples,current monitoring methods are insufficient to support preventive protection.This paper,based on the characteristics of grotto temple rock masses—which encompass slopes,underground engi-neering,and cultural relics—reviews the development of stability monitoring technology for slopes,underground en-gineering,and cultural relics rock masses both domestically and internationally.It summarizes the basic characteris-tics and key scientific and technological challenges in the monitoring process.(1)Slope rock mass stability monito-ring began with prevention efforts in the 1860 s.By the 1980 s,monitoring indicators expanded from surface to un-derground measurements,improving efficiency and accuracy.In the late 1990s,multi-technology integration and complementary monitoring became the main development trend.(2)Related monitoring technology exploration be-gan in the 1950 s.By the 1970 s,standardization,procedures,and quality of monitoring were largely established.In the 1990 s,monitoring evolved towards refinement and big data,forming a three-dimensional integrated big data analysis platform encompassing aerial,surface,and subsurface data.(3)In the 1980 s,grotto rock mass stability technology primarily relied on traditional engineering geological surveys and mapping.In the early 21st century,based on the preventive protection of grottoes,numerous projects related to grotto stability were implemented in Chi-na.However,due to the complexity of grotto temple rock masses and their cultural relics,a specialized grotto rock mass stability monitoring system has not yet been developed.The future research direction for cave temple rock mass stability monitoring should be based on qualitative and quantitative evaluation.Subsequently,key monitoring fac-tors,accuracy,frequency,and the coupling relationships between various factors should be determined based on this evaluation.Ultimately,the goal is to establish a rock mass stability monitoring system that covers regional sta-bility,cave stability,and key block stability of cave temples,incorporating cross-scale,multi-field coupling,and spatiotemporal integration.Based on the current status of these fields,this paper identifies challenges and future de-velopment trends in rock mass stability monitoring for grotto temples,providing support for the conservation and safety of grottoes in China.
