摘 要:
鉴于山坡泥石流的危险性主要表现为冲击破坏作用,运用能量守恒原理,将泥石流场地危险性评价公式改进为“危险度=能量×频率”。初步探讨了山坡泥石流场地易损性问题,给出了场地易损性的评价指标和计算公式,依据“风险度=危险度×易损度”计算了山坡泥石流场地风险性,并给出了具体评价实例。

摘 要:
Applying to the conservation law of energy, the formula of hazard assessment was approved as“hazard = energy×probability”.The preliminarily discussion of site-specific vulnerability of hill slope debris flow was made and the assessment method and formula were given.These methodologies were applied to Beibei district of Chongqing and a good agreement was achieved.
