摘要
在介绍了重庆市北碚区醪糟坪泥石流概况、主要特征基础上,重点对其稳定性评价的方法进行了分析,提出了泥石流稳定性中,除应确定其特征值外,还应分区、分模式、分时段区别分析,才能准确把握泥石流的稳定性。对醪糟坪泥石流按其运动规律,将其分为形成区、流通区和堆积区,在计算确定了泥石流特征值后,对各区的稳定性按其变形破坏的特征确定了稳定性分析的模式,并进行了分别分析计算。
The debris flow in Beibei district, Chongqing city and its main features are introduced. The stability evaluation methods are analyzed and it is suggested that for the stability of debris flow, in addition to the characteristic value, the stability should be analyzed by partition, sub - model and at different points of time in order to accurately know the debris flow stability. The Laozaoping debris flow can be divided into the formation area, circulation area and stack area by motion law. After calculation of debris flow characteristic values in different areas, the stability analysis model for different areas is determined by their faliue features for conducting analysis and calculation of each area.
