Dangerous rocks is one of the major geological hazard for railway and highway. T he paper systematically summarized the domestic and foreign researches on assessment method of stability of dangerous rocks from four perspectives including stability,analysis approaches,status evaluation and treatment. It studies the application of manual observation,stress and strain monitor,differential detection on electromagnetic field and laser scanning in stability analysis of dangerous rocks,pointing out the visible error occurred due to the limitation posed by equipment precision,measurement approaches and environmental conditions. On this basis,the paper works out a new method based on vibration characteristics for stability analysis,which by making use of a non-contact means of detection enjoys great application prospect in both railw ays and highw ays.
