陕西紫阳县磨子沟泥石流特征及危险性分析

Geological Features and Risk Analysis of the Mozigou Debris flow in Ziyang,Shaanxi

磨子沟在2010年7月陕南特大暴雨后发生泥石流,引发多处滑坡,部分居民房屋被摧毁;大量碎石、泥砂堆积于沟口,造成公路堵塞。现在沟内依然有大量松散物源,存在泥石流隐患,威胁沟内居民点及公路。采用单沟泥石流危险性评价方法,结合现场勘查,分析磨子沟泥石流形成条件、类型、发育特点及危险性,为地质灾害避险及治理提供地质依据。

The Mozigou debris flow occurred after rainstorm in the south of south Shaanxi in July 2010.Many landslides occurred and some residents homes were destroyed.This paper has a discussion on forming conditions,type and risk of the debris flow based on remote sensing image explanation and field investigation.
