滑坡是一种物理地质现象,是一种地球上广泛存在着的表生地质灾害。构成天然斜坡和人工边坡的岩体,在重力、地表水、地下水及震动力等的作用下,失去原有的平衡和存在的基础,发生了危害性的变形破坏,致使斜坡倾倒和滑落下大量的岩土堆积物,从而导致交通中断,村镇埋没,江河堵塞,水库淤填等而酿成巨大灾害。从本质上讲,它是由地质作用引起地壳成分和构造发生变化而产生的现象。由于地壳不是静止的,而是时刻在运动着和变化着的,因而这种现象的产生也不会终止。就是说,只要地球存在,滑坡就永远不会消灭。
Landslide is a physical and geological phenomena, is a kind of epigenetic geological disasters exist on Earth. Under the action of gravity, surface water, groundwater and shaking force, the rock mass that forms natural slopes and artificial slopes loses the original balance and foundation of existence, and has undergone harmful deformation and destruction, causing the slopes to fall and slide down Large amounts of rock and soil accumulation, resulting in traffic disruptions, buried villages and towns, river congestion, siltation and other reservoirs caused a huge disaster. In essence, it is caused by the geological changes in the composition and structure of the crust. Since the earth’s crust is not static, but always moving and changing, so this phenomenon will not cease. That is, as long as the Earth exists, landslides will never be eliminated.
