| 摘 要： | 三峡库区奉节县新城建设大大改变了李家大沟中下游的地质环境,泥石流将直接威胁到新城区的建设和人民财产的安全。从工程地质角度出发,对李家大沟泥石流的形成环境(地层岩性条件、构造条件、地貌条件、气象条件、植被发育及人类工程活动)、基本特征(形成区和流通区特征)和形成机制进行了详细的系统研究,对泥石流的危害性和发展趋势做了预测评价,并提出了合理科学的建议。

| Abstract: | Reservoir area of Fengjie County's new city construction in Three Gorges is greatly changing Lijia Gully's engeering geological environment at midstream and downstream. The debris flow will threaten the construction of the new city and security of local people's property directly. The thesis proceeds from the point of geological project, the formation conditions(lithologic character, structure condition, geomorphic condition, meteorological condition, vegetative cover and human engineering activities), essential features(features of forming areas and circulating area) are systematically studied in detail. The calamity and development trend are predicted, and rational suggestions are proposed. |
