山西省平定县寨坪沟泥石流灾害特征及预警
|
摘要
山西省平定县泥石流灾害比较发育,其中太行山中段西麓泥石流发育具有典型特征,该泥石流沟位于冶西镇西南的南川河源头,流域范围内有居民居住,泥石流灾害严重威胁当地居民的生命财产安全。在实地调查的基础上,对寨坪沟泥石流的形成条件和基本灾害特征进行了分析,并根据其起动机理,采用了相应的泥石流预报公式进行预警,提出了预警临界降雨值及判据。
Characteristics of debris flow in Pingding county is serious, where is located on the west foot of the middle section of Taihang Mountain. It is located in the southwest of Yexi Town and the source of Nanchuan River. The river basin is inhabited by residents, and the debris flow disaster has seriously threatened the safety of local residents. Based on the field investigation, this paper analyzes the forming conditions and the basic disaster characteristics of the debris flow in Zhaiping Gully. According to the incipient mechanism, a corresponding debris flow forecasting equation is used to warn for the gully.
