THE MAIN FACTORS AND MECHANISM EFFECTING ON THE EARTHQUAKE RESISTANCE STABILITY OF GROTTOES RELICS AND COUNTERMEASURES

摘要

The Buddhist art of grottoes is an important part of splendid culture in the long history of China, which is also highly valuable tourism resources. The grottoes and relics have been suffering the erosion of wind, sand, raining water, burning of sunshine, agency of earthquakes and effect of human activity that they come to the state of many types of disease. Furthermore, many grottoes are situated in the areas subject to high seismicity and high intensity, so it is necessary and pressing to enhance countermeasures of earthquake resistance and disaster reduction for grottoes relics preservation, which is of course important for the human civilization to be kept. In connection with characteristics and disease features of grottoes, the internal actions and external environment conditions causing earthquake resistance stability of grottoes, such as weather and climate features, seismicity, hydrology features, environmental engineering geology, structure of grottoes and the particularity of cultural relics and human factors, are analyzed in detail.,the causing mechanism is expounded, and the controlling countermeasures are proposed. It can be served as basis for the scientific conservation and restoration of grotto relics.
