Comprehensive Mitigation and Control of Rockfall Hazard

Article Preview

Abstract:

Rockfall is one kind of important geohazard. Due to its complexity of trajectory, it is difficult for treatment designing in slope engineering. This paper employs a methodology for estimating rockfall trajectory using a series of established formulas, and then discusses the advantage and also disadvantage of existing controlling measures for rockfall mitigation. Based on site survey, calculation results and site geologic conditions, various protective structures such as retaining walls, safety net system and vegetation or plants, are suggested to mitigate and control the rockfall hazards comprehensively, which illustrates great advantages in technology, economics and environmental protection in a case study of rockfall hazard treatment. The idea and methodology presented herein is referential for similar slope problems.
