| 摘 要： | 野外观测和实验模拟表明，泥石流堆积是通过若干阵流在保持相对完整的形态下叠加形成的。本文利用蒋家沟阵流的观测数据，根据阵流流深一流速关系和各自分布，并结合浊流的堆积分布、数值模拟的流深、堆积分布，提出泥石流堆积厚度的分布具有与流深相同的负幂分布形式，并估计了分布指数的下限。结果表明，泥石流堆积厚度的分布很不均匀，分布的估计为堆积区的危险性的划分提供了新的定量依据。

| Abstract: | The section from GaoPing to JiXin of HuRongXi freeway lies in the northeast edge of YunGui tableland belonging to the residual valley of WuLing mountain,DaLou mountain and BaMian mountain, of which the landform is middle-low mountain to low-middle mountain, ground altitude is more than 400 meters, the landform is complex,and the engineering conditions of roadbed is very complex and variable,so ill geological phenomena are well developed,such as landslide,rock-falling and Karst engineering problem. Taken this project for example, engineering geological characteristic is introduced briefly,the prevention and the control measures are put forward in the paper.It is important and necessary for the project to go on wheels. |
