崇州市鸡冠山乡苟家村大岩沟泥石流成因分析
|
摘要
泥石流灾害是灾区重大的地质灾害之一。给工程建设带来很多不利的影响。崇州市鸡冠山乡苟家大岩沟为泥石流多发段。泥石流具有规模较大、分布较广、发生频率高、致灾作用强烈的特点。本文通过系统分析工程区陡峻的地形条件、发育的区域构造、软硬相间的岩层、广泛分布的堆积物、降雨量降雨集中的气候条件、地震对泥石流的影响,揭示了崇州市鸡冠山乡苟家大岩沟泥石流的成因。为本地区的工程建设提供了指导意义,也为同类地区的泥石流的成因提供了借鉴意义。
The flow-prone is one of the fatal geologic hazards.It gives construction a lot of negative impacts.Da Yangou is a debris flow-prone area in Goujia County,Jiguan Township,Chongshan City,Sichuan Province.Its features are on a large scale,wide distribution and high frequency with serious disasters.Through systematical analysis on the steep topography,the structure of growth of debris flow,the lithological character of different rock strata,wide distribution of deposit,the climate condition with concentrated rainfall and the influence of earthquake on debris flow in the disaster zone to reveal the cause of debris flow in Dayangou,Goujia County.This paper provide a guidance to the construction in this region,also a reference for the causes of debris flow in similar regions.
