摘要
滑坡是一种地质灾害,是地貌演化的一种方式,本质上是重力流,像岩石碎块或泥土这样的物质在自身重力的影响下从高处向低处滑动,因此,滑坡多发生在山区和丘陵地带。发生滑坡的山体通常比较松散,内部有一些不稳定的层面——滑动面,滑动面在一些诱发因素如降雨的影响下,不稳定层面的黏附力减小从而引发山体滑坡。滑坡会导致河流堵塞,交通阻断,电力通信受损,使人们的财产受损。论文结合工程案例,对潜在性的滑坡稳定性做出了评价并提出了相应的防治措施。
Landslide is a kind of geological hazard and a way of geomorphic evolution. It’s essentially a gravitational flow, things like pieces of rock or dirt slide from higher to lower under the influence of their own gravity, therefore, landslides occur in mountainous and hilly areas. Landslides are usually relatively loose and have unstable layers inside them, as sliding surfaces, under the influence of some inducing factors such as rainfall, the adhesive force of the unstable plane decreases, which leads to the landslide. Landslides can block rivers, cut off traffic, damage power and communications, and damage people’s property. Combined with the engineering case, the paper evaluates the potential stability of landslide and puts forward the corresponding prevention measures.
