According to dynamical principle and man\|made debris flow characteristics in Shenfu\|Dongsheng mine site, dynamic process of man\|made quasi\|debris flow initiation motion was analyzed. The experiments of artificial simulation rainfall and setting water rushing of quasi\|debris flow in field showed that:1)the initiation motion of quasi\|debris flow on slope was decided by rainfall intensity and precipitation and slope inclination; 2)the initiation motion of quasi\|debris flow in gully was decided by upper reaches coming water and slope inclination of gully bed; 3)softened(saturated) and dry loose solid material coexisted in man\|made quasi\|debris flow process. On the base, the initiation motion potential function of quasi\|debris flow in gully was calculated.Finally,transmitting process of motive force and enrgy in debris flow process were discussed.

Debris flow of Taoguan Ravine is a large and one of the most representative debris flow ravines. It is famous for the historical event "Water swashing Taoguan",and nowadays it is more noticeble as a highway debris flow because of the construction of the round uighway of Jiuzhaigou. The paper gains more clearly cogniton on debris flow characteristics based on the local investigation,experiment and some parameters computer of the debris flow. The debris flow control method is different from general control engineering. Its stress lies in available defending on road engineering an properly dealing with the debris flow entring Minjiang River. Through the measure above and virtual up-removal of the debris flow depositlonal area ralative to the road, a series of passive condition, which are induced by the deposit ional area,will be changed so emphsizing on defending of target, new structure and environmen tal consciousness are the characteristic of the debris flow control in Taoguan Ravine, and this will be an important idea in similar hazards research and engineering design.

Debris flow is one of the primary natural geo-hazards in mountain regions whose geological environment is worse.There are many achievements of debris flow disciplinarian,but the study thought on debris flow need to be expanded and perfected.The new study train of thought(by the form condition,the evolution steps and pattern,and relativity analysis,the whole debris flow's formation and evolution mechanical process was analyzed and evaluated) is important for engineering in mountain region.In this paper,from the view of engineering geology,the debris flow characteristics of the Sihe Gully in the tributary(Guanliao River) of Dadu River where is a hydroelectric power station were studied.The formation condition(for example:lithologic character,structure condition,geomorphic condition,meteorological condition,vegetative cover and artificial activities.) and basic characteristics(characteristics of debris flow gully and debris flow accumulation) of the tributary(Guanliao River) were presented in detail according to the engineering geology analysis method in the paper.The formation evolution steps of the Sihe gully debris flow and its mechanism model(primarily barrage groove model and then gradually collecting groove model) were put foreward.The stability of slopes(possible matter source of debris flow) along the debris flow gully was analyzed in detail.By the combined mathod of quantitative and qualitative analysis,the scientific prediction for the trend of the debris flow activities was put forward.The engineering geological analysis method is an important method especially for engineering constructions in the western Region of China.

泥石流作为地质环境较差的山区的主要自然灾害之一,对它的研究尤其是泥石流规律方面的研究已取得了较大的成绩。但是对于泥石流的研究思路却有待进一步发展和完善,这在很大程度上将对山区的工程建设有很重要的指导意义。论文从工程地质研究思路的角度出发,对位于大渡河支流官料河上某水电站下闸址区的斯合沟泥石流进行了研究。文中采用工程地质分析的方法对大渡河次级支流斯合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,提出了该泥石流的形成演化过程及其机制模型(初期是堰塞式沟谷型泥石流,后期逐渐转向汇聚式沟谷型泥石流)。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。将定性分析和定量分析相结合,对泥石流的活动趋势以及可能泥石流的体积(未来泥石流形成将主要是在面蚀和沟蚀作用下的坡面泥石流。泥石流规模较小,且由于沟谷中下游坡降的进一步减缓,形成的泥石流物质一般将沿途停积,实际进入官料河内的体积很小)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有着积极的指导意义。
