摘要
通过对小后沟流域的实地走访调查和对泥石流流速、流量和冲击力等的计算,研究了小后沟泥石流的基本特性,根据这些特征,判断小后沟泥石流属易发型,具备发生泥石流的基础条件。既有防护措施总体防灾能力较差,存在较大的安全隐患。本文结合小后沟泥石流成灾特征,充分利用1号渣堆的固有地形,提出了"拦排结合"的泥石流综合治理方案,设置了一处停淤池,以期达到固源护坡和弱化泥石发展的目的。
Based on the field investigation of Xiaohougou watershed and the calculation of flow velocity,flow rate and impact force of debris flow,the basic characteristics of Xiaohougou debris flow are studied.According to these characteristics,it is judged that Xiaohougou debris flow is easy to occur and has the basic conditions for debris flow.The existing protection measures have poor disaster prevention ability and have great potential safety hazards.In this study,we combined with the disaster characteristics of debris flow in Xiaohougou,taking full advantage of the inherent topography of No.1 slag pile,a comprehensive control plan of debris flow with"interception and drainage"was put forward,a desilting pond was set up,so as to achieve the purpose of solid source slope protection and weakening mudstone development.
