某高陡边坡崩塌落石运动特征分析及其防治

Falling rock movement characteristic and reinforcement measures of a high steep slope

长白山天池观光长廊段边坡于1998年8月1日发生崩塌,导致重大的伤亡事故,天池地区旅游业遭到重创。为对其治理,以该段边坡为例,对其地质条件进行了详细分析,阐述了边坡岩体特征、边坡形态、岩石物理力学特性以及雨水、风化等内外营力的综合影响是崩塌产生的原因。根据崩塌落石运动与边坡高程相关的特征,对其运动速度和运动轨迹进行了分析,在此基础上提出了"缓坡段拦截"和"陡坡段遮挡"的防治措施。

Collapse is one of the geological hazards of the slope and the loss is always tremendous. The collapse of the gallery slope in the Tianchi region of the Changbai Mountain took place in Aug 1, 1998, which lead to great casualty. In order to reinforce it, we analyze the geological condition in detail and set forth all kinds of the reasons to the collapse, such as character of rock mass, shape of the slope, physical and mechanical character of rook, rainfall and weather etc. We present the measures such as obstructing and enveloping to reinforce it based on the coeerlative characteristic between the falling rock movement and the stope altitude. The measures are proved to be highly effective.
