| 摘 要： | 泥石流作为地质环境较差的山区的主要自然灾害之一,对于泥石流的研究思路的进一步发展和完善,在很大程度上将对山区的工程建设有很重要的指导意义。从工程地质研究思路的角度出发,对位于川藏公路二郎山隧道西口和平沟泥石流进行了研究。采用工程地质分析的方法对和平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、植被发育及人类活动)、基本特征(泥石流沟的基本特征、泥石流的堆积特征)进行了系统的研究,并在此基础上对泥石流沟沿岸的岸坡稳定性(可能泥石流的物源)等进行了评价分析。对泥石流的活动趋势以及可能泥石流的方量做出了较为科学的评价预测。经过这样的系统分析对工程建设中的泥石流防治提出了治理设计方案。

| Abstract: | Debris flow is one of the primary natural geological hazards in mountain areas with worse geological environment, so the development of research thought is important to engineering eonstruet of mountain areas. In this paper, the debris flow characteristics of Heping gully are studied, which located in the west outlet of Erlang mountain Tunnel, Sichuan-Tibet Road. The formation eondition( such as strata litho logic character, structure condition, geomorphic condition, meteorological condition, vegetative cover and artificial activities) and basic characteristics (eharaeteristies of debris flow gully and debris flow accumulation) of Heping gully are presented in detail according to the engineering geology analysis method in the paper. In addition, the stability of slopes along the debris flow gully, the trend of the debris flow activities and the possible volume are also evaluated and predicted scientifically. Based on the systematic analysis, different schemes to prevent and control the debris flow in engineering construction ean be put forward reasonably. |
