Abstract: Our country is a country with a geological disasters,dangerous rock is high steep slope hills region one of the main types of geological disasters, with a high frequency,every year, all can lead to a large number of casualties,all kinds of engineering facilities under different degree of damage, cause serious economic losses to the country.This article is based on the analysis of a large number of relevant research data at home and abroad,mainly from the destruction of dangerous rock instability mode, stability calculation, impact force calculation and prevention and control measures four aspects to analyze the existing achievements,On the basis of the development trend of the research direction were discussed.Hope research to our country mountainous area disaster prevention and control of dangerous rock engineering practice has positive significance.

Keywords: Dangerous rock; Instability mode; Stability calculation; Impact force calculation; Prevention and control measures
