山体滑坡是指部分不稳定的岩土由于重力的作用沿山体边坡下滑并在一定的软弱结构面上剪切位移的现象。在水库、河流、港口或者海岸等具有一定水深的区域发生山体滑坡，将会产生巨大的水波沿岸传播，冲击涌浪会对船舶的安全构成一定的威胁，而落入水中的土石还会堵塞河道、恶化航道水流条件。本文通过河道模型试验，对滑坡涌浪作用下船舶通航安全的问题进行深入研究。试验研究得到滑坡涌浪在直道和弯道处的衰减规律，船舶横摇运动幅值与山体滑坡位置、滑坡量大小、船舶与滑坡点距离等因素有关，结合试验数据，为船舶航行安全提供一定的理论依据。
The landslide is a phenomenon that a part of the rocks and soils on the slope of the mountain produces shear displacement along a certain weak structural surface and moves to the bottom of the slope as a whole under the action of gravity. Landslides, these are in a region of water depth such as reservoirs, rivers, ports or shores, will produce huge waves of water waves along the coast. The impact of the waves will pose a threat to the safety of the ship, and the soil and rock falling into the water will clog the river and deteriorate the waterway. In this paper, we study the navigation safety under the action of the landslide surge, through the river model test. The attenuation law of landslide surge at the straight and curved path is obtained by the experimental study. The amplitude of the ship rolling motion is related to the landslide position, the size of the landslide, the distance between the ship and the landslide point etc. Then the study provides a certain theoretical basis for the safety of the ship navigation.
