| 摘 要： | 虎峪沟位于山西省太原市西山地区,该区泥石流的发生直接威胁着太原市城西一带居民的生命财产安全。为进一步查清该区泥石流的危害程度,以虎峪沟潜在泥石流为研究对象,在其流域地质坏境调查的基础上,对西山地区构造活动、河流下切形成的复杂地形地貌、自然风化及人类工程活动堆积的松散堆积物物源、不均衡降雨等各种作用相伴生的地质过程进行了研究,并进一步采用危险度评价分析方法对虎峪沟泥石流进行了分析。结果表明,虎峪沟泥石流的危险度Rd为0.768,属高度危险的泥石流沟,若爆发仍将对下游造成威胁。

| Abstract: | Huyu Valley is located in the Xishan area of Taiyuan City,Shanxi Province.The occurrence of debris flows in the valley directly threatens the security of the local people.To further identify the hazards of debris flows in the area,the geologic processes are studied through the investigation of potential debris flows in the valley,including tectonic activities in Xishan area,complex topography and geology formed from stream incision,loose deposit caused by natural weathering and human activities,and unbalanced distribution of rainstorms.A analytical approach to risk assessment is used to analyze debris flows in the valley.Results indicate that the risk degree of debris flows in the valley is 0.768,being a highly dangerous degree,and they may threaten the downstream if erupting. |
