泥石流防治措施与冲击力研究进展

Debris flow is a worldwide natural hazard that has been common in all historical periods, especially in mountain area with frequent occurrence of earthquakes, causing severe loss of life and property every year.To cope with this sudden, violent, destructive disaster, a series of prevention and control measures have been applied.The measurement of debris flow is summarized systematically in this article.Two kinds of initiatives, namely structured-measures which include check dam, net barrier, drainage channel, sedimentation tank, planting etc. and warning system for unstructured-measures, are used to prevent or reduce the consequence.Static models and hydraulic models are exerted to estimate the impact force of debris flow, furnishing empirical coefficient for structured-measures design.
