| 摘 要： | 平山县是河北省太行山区主要泥石流地质灾害频发区，每年7～8月份强降雨期间，沟谷源头侧壁岩土体在雨水的浸泡下失稳破坏，形成崩塌与滑坡，崩滑的岩土体与沟源洼地中积聚的洪水迅速混合形成泥石流。本文认真分析了该区泥石流的分布概况，研究了泥石流灾变的形成特征，并从泥石流形成的物源条件和动力条件两方面分析了泥石流发生的机理和崩滑转化机制。 |
| 关 键 词： | 泥石流 形成特征 灾变机理 平山县 |

| Abstract: | Taihang Mountain,Pingshan County of Hebei Province,is the primary area where debris flow always occur.During rainy season in every August,the rock and soil will fail with the rainwater dunking,and debris flow will be forming as soon as the dilapidation and land sliding occur.In this paper,the distributing in space-time and forming characteristics of debris flows are analyzed;furthermore,based on studying of substance conditions and dynamic conditions,the forming mechanism of debris flow are analyzed. |
| Keywords: | debris flow forming characteristics forming mechanism Pingshan county |
