浅层滑坡诱发沟谷型泥石流的物源条件
Research on Material Source Factors of Gully-Type Debris Flow Caused by Shallow Landslides
流域内暴发大量浅层滑坡会导致沟谷型泥石流发生,但鲜有研究揭示滑坡物源量和沟谷泥石流形成条件.因此,基于泥石流的形成机理对这类型泥石流形成需要的滑坡物源条件进行评价,分析2010年福建顺昌元坑镇宝庄村沟谷型泥石流和浅层滑坡之间的关系,进而提出这类泥石流发生的物源条件模型.结果表明:流域内滑坡面积越大,土层厚度越大,则越有利于暴发浅层滑坡诱发的沟谷型泥石流.因此,可运用滑坡面积(A0)、流域面积(A)和土层厚度(h)划分某区域内沟谷泥石流的易发等级.对于华东区域的沟谷:流域的平均土层厚度为h时,当发生滑坡的总面积(A0)与流域的面积(A)关系为:A0/A≥0.045×(3/h),极容易暴发沟谷型泥石流;0.02×(3/h)≤A0/A≤0.045×(3/h),较容易暴发沟谷型泥石流;0.02×(3/h)≥A0/A,不容易暴发沟谷型泥石流.当进入沟道的滑坡总面积(AL)与流域的面积(A)的关系为:AL/A≥0.03×(3/h),极容易暴发沟谷型泥石流;0.006 5×(3/h)≤AL/A≤0.03×(3/h),较容易暴发沟谷型泥石流;0.006 5×(3/h)≥AL/A,不容易暴发沟谷型泥石流.所提出的模型适用于分析福建省浅层滑坡诱发的沟谷型泥石流形成机理.模型简单,输入所需的数据是易于测量的流域面积和流域内的浅层滑坡面积.该方法可根据新的局部条件对阈值参数进行调整,可用于其他地区浅层滑坡诱发的沟谷型泥石流案例分析.
Few studies pay attention to revealing the relationship between the amount of landslide material and the formation of gully debris flow, although a large number of shallow landslides in a watershed can lead to gully-type debris. Thus, the landslide source conditions required for the formation of this type of debris flow are evaluated based on the mechanism of debris flow formation. To analyze the relationship between the debris flow by shallow landslides in Baozhuang Village, Fujian, in 2010. And the material model of gully-type debris flow by shallow landslides was proposed. The result shows that the larger the landslides area in the catchment, the greater the possibility of gully-type debris flow. The landslide area (A0), catchment area (A) and soil thickness (h) can be applied to classify the susceptibility class of gully-type debris flow by shallow landslides. For the gullies in the East China region:when the average soil thickness of the catchment is h (m), the total of area where landslides occur (A0) is related to the area of the catchment (A) as:it is very high probabilities of debris flow formation when A0/A≥0.045×(3/h). The probabilities of debris flow formation is medium when 0.02×(3/h)≤A0/A≤0.045×(3/h). The probabilities of debris flow formation is very low when 0.02×(3/h)≥A0/A. When the total area of landslides entering the channel (AL) is related to the area of the catchment (A) as:it is very high probabilities of debris flow formation when AL/A≥0.03×(3/h). The probabilities of debris flow formation is medium when 0.006 5×(3/h)≤AL/A≤0.03×(3/h). The probabilities of debris flow formation is very low when 0.006 5×(3/h)≥AL/A. The empirical models are simple, and the data needed necessary for the input are easily measurable catchment areas and landslides area. The approach may be applied to the analysis debris flow by shallow landslides in other areas due to simplicity, when adapting the threshold parameters according to new local conditions.
