急陡沟道泥石流物源主要来源是崩塌、滑坡堆积体,堆积体的起动是急陡沟道泥石流冲出量巨大的主要原因。堆积体的物质组成、赋存特征及渗透、径流状态是造成其起动模式不同的本质原因,而较大的纵坡降为其起动提供了良好的地形条件。根据汇水条件及渗透特性设计了2组模型箱试验,模拟坡体内不产生稳定渗透及有稳定渗透条件下的破坏模式。实验表明急陡沟道泥石流起动有“消防管效应”和“坡体流态化”2种基本的模式,前者出现在不饱和或高渗透系数坡体,后者出现在具有一定细颗粒物质的土体中。其中消防管效应仅沿径流路径形成深而窄的侵蚀沟道,且搬运距离与水动力的持续性有关,固体物质搬运作用弱;坡体流态化主要特征为初期的缓慢渗透破坏及后期瞬时流动剪切破坏,侵蚀形成较宽的沟道,且侵蚀量相对较大。

Generally, collapse and landslide are the main sources of granular deposits while the initiation of deposits is triggered by the tremendous runoff from steep longitudinal gully. Substance composition, topographic condition and catchment characteristics directly affect the models of deposits initiation, and larger longitudinal grade provides better topographic condition for the initiation. Several sets of experiments on model casing were designed to simulate the failure mode of slopes under the states of stable and unstable seepages according to catchment and penetration characteristics. It was revealed from the experiments that the initiation of granular deposits had two fundamental modes, that is, fire hose effect and static liquefaction. The former one generally happens at the unsaturated slope or the slope of high permeability while the latter case occurs at the soils containing fine particles. It was concluded that the fire hose effect could generate the deep and narrow eroded channel along with the runoff, the movement distance was related to the continuous hydrodynamic force, and the transporting capacity of solid substances was weak. In addition, slope fluidization was featured with slow seepage failure at the early stage, instantaneous shear failure at the late stage, and wider channel came out due to serious erosion.

Key words: Steep longitudinal gully, Debris flows, Initiation model, Coupling mechanism.
