Background

The landslide refers to the action and phenomenon that a certain part of rock soil on a mountain slope moves integrally to the lower part of the slope along a certain weak structural plane (zone) under the action of gravity, including the gravity of the rock soil and the action of dynamic and static pressure of underground water, and is one of common geological disasters. The geographical conditions of landslide are as follows:

firstly, rock-soil mass is a material foundation for generating landslide.

And secondly, the rock and soil bodies forming the slope can slide downwards only when being cut and separated into discontinuous states by various structural surfaces.

And thirdly, landslide can occur only when the landslide is located at a certain landform part and has a slope with a certain gradient.

And fourthly, the groundwater activity plays a main role in landslide formation.

The main inducing factors of landslide are: the continuous scouring of surface water bodies such as earthquakes, rainfall and snow melting, scouring and soaking of surface water, rivers and the like to slope toe; unreasonable human engineering activities such as excavation of slope toe, loading of the upper part of a slope body, blasting, reservoir flood discharge, mining and the like, tsunami, storm surge, freeze thawing and the like. Because landslide is a natural phenomenon, in present geographic teaching, field demonstration teaching cannot be performed, the teaching of a geographic teacher on the landslide only exists in the theoretical knowledge of a textbook, students cannot deeply feel the reason of the landslide, the characteristics of the landslide and the harm brought by the landslide, and obviously the teaching requirements of the teacher cannot be met.
