| 摘 要： | 番字牌西沟为北京山区具代表性的一条泥石流沟，1989年和1991年两次暴发泥石流，致死3人，造成严重灾害。泥石流具有容重大（2.0t/m^3），搬运固体物质粒径粗，固体物质以沟床堆积物补给为主，平均约10年一次中小规模、50年一次大规模活动周期等特征，针对泥石流特征，制定出三套减灾工程规划方案，并进行方案优化探讨，提出优化方案供减灾使用。

| Abstract: | Fanzipaixi Gullly is a representative debris flow gully in the mountain area of Beijing. Debris flow had taken place twice hazards and three persons were killed from 1989 to 1991 in the basin. The major characteristics of debris flow are follow as:1.density is 2.0 t/m 3; 2.solid state material composing fluid are thick; 3.the majority of solid material stemes from gully_bed deposits;4.the period of a large_scale debris flow occureence is about fifty years and medium or small about ten years. Three engineering plans for disaster relief have been put forward. The optimal plan has been reco mmended after comparing. |
