    FEATURES AND PREVENTIVE COUNTERMEASURES OF DEBRIS FLOW IN A MOUNTAINOUS SCENIC SPOT,TAIZHOU COUNTY,ZHEJINAG PROVINCE

    • 摘要: 浙江台州某景区属于中、低山区,地形坡度变化急剧,多悬崖峭壁,地形陡峭。现场调查的景区内共8条泥石流冲沟分别位于北西向流向小溪的两侧,冲沟规模虽不大,但纵比降为485~864,为泥石流发育提供较大势能。2017年7月5日台州地区的局地暴雨引发8条冲沟暴发泥石流,其中冲沟1至冲沟7携带的碎石堆积阻碍了游路,冲沟8携带的碎石淤积于景区售票办公室内,造成严重财产损失。本文对8条冲沟进行了详细的现场调查,分析了冲沟8泥石流的基本特征和形成条件。计算优化冲沟8泥石流的重度、流速、一次泥石流总量、一次泥石流冲出的固体物质总量等特征参数,据此提出了防治方案。本文对景区及附近景区泥石流沟谷的调查和防治具有一定的参考价值。

       

      Abstract: A scenic spot in Taizhou, Zhejiang province locates in a mountainous area, the terrain changes sharply, and thus many cliffs stand steeply. According to the field research, there are 8 debris flow gullies lay along a stream flowing in northwestern direction. Although small in size, the longitudinal gradients of these gullies are 485~864,which accumulate potential energy for the outbreak of debris flows. A rainstorm on July, 5, 2017 triggered debris flows in these 8 gullies, 7 of which carried debris, piled up and blocked the tour road. Large amount of debris of No.8 gully rushed in the ticket office, causing a serious loss to the scenic spot. In this paper, a detailed field study was carried out on these gullies, and analyzed the features of them and conditions that would trigger debris flows in these gullies. Taking debris flow in No.8 gully for example, many characteristic parameters of which were calculated, such as the bulk density, density, volume of debris for once outbreak, total volume of debris for once outbreak, etc. Based on these parameters, this paper put forward some preventive countermeasures, which could be a reference to the prevention of other debris flows near this scenic spot.
