| 摘 要： | 石家庄西部太行山区是河北省主要泥石流地质灾害频发区，该区地质构造强烈、岩石破碎、节理裂隙发育、沟谷狭窄、沟床比降大．每年7～8月份是强降雨期．沟谷源头侧壁岩土体的崩塌和滑坡与洪水混合，极易形成泥石流。该文认真分析了该区泥石流发生的时空分布和形成特征，研究了泥石流灾变的物源条件和动力条件，并将该区泥石流类型定为暴雨激发-崩滑演变-沟谷型泥石流。 |
| 关 键 词： | 泥石流 灾变机理 太行山区 石家庄西部 |

| Abstract: | The Taihang Mountain area in west of Shijiazhuang city is the primary area where debris flow always occurred.Because of the heavy geologic structure,fragmented rock and big gradient ratio of ravine,during rainy season in every July to August,debris flow formed easily as soon as the dilapidation and land sliding occurred.In this paper,the distributing in space-time and forming characteristics of debris flow are analyzed;furthermore,the substance conditions and the dynamic conditions are studied,and the debri... |
