Abstract
Located in northwest China, the Mogao Grottoes site at Dunhuang is one of first group of world cultural heritage sites in China. Due to the tectonic movement, long-time weathering unloading actions and construction of caves, there are cross-cutting structural cracks, vertical, horizontal, lengthwise tension cracks, and unloading cracks in the rock body of the Mogao Grottoes. The strong rainfall, sand and wind, and earthquake also threaten the permanent preservation of the Mogao Grottoes. Aiming at the main engineering geology problems at the Mogao Grottoes, various measures had been taken to ensure the stability of most cliff rock. The ongoing researches and construction of a monitoring and forewarning system at the Mogao grottoes can provide continual monitoring, allowing for the transition from rescue conservation to preventive conservation.
