| 摘 要： | 坚硬岩性地区的泥石流暴发频率较低在定性上基本可以概括岩性与泥石流暴发频率的关系,但目前还没有定量地描述岩性与泥石流暴发频率的关系。以四川省17个泥石流流域作为研究对象,通过现场调查研究泥石流形成区和堆积区粗化层颗粒的岩性、硬度以及泥石流的暴发频率,得出：①泥石流堆积区岩性组成特征基本可以代表形成区的岩性组成特征;②用地... |
| 关 键 词： | 泥石流 暴发频率 岩性 坚固系数 |

| Abstract: | It is qualitatively described the relationship between the hardness of rock in catchment and the triggering frequency of debris flow: the harder of rock in catchment,the lower frequency of debris flow is.But there is no quantitative relationship of the hardness and the triggering frequency.In this paper,17 catchments of debris flow in west Sichuan Province were investigated.The hardness of catchment,the triggering frequency of debris flow,and their relationship were researched.One can obtain the results fro... |
