Side slope landslide teaching demonstration device and experiment method

Abstract

The invention discloses a side slope landslide teaching demonstration device and an experiment method. The side slope landslide teaching demonstration device can utilize the prior art to simulate landslide under various working conditions like rainfall infiltration, side slope upper-portion loading, earthquake dynamic load, upper-portion reservoir water storage, and a system comprehensively demonstrates a side slope landslide damaging mechanism; progressive sliding of side slopes different in gradient, compactness and soil quality is demonstrated; grid lines of an observing area on an experiment groove are utilized to record landslide range of the side slopes, calculate size of landslide, analyze difference between an observing result and a calculating result and comparing difference between an experimental and a theoretical result. The side slope landslide teaching demonstration device aims at demonstrating basic phenomena of soil mechanics, revealing mechanical principles in the soil mechanics and comparing practicability of landslide methods like a bishop's slice method and Sweden slice method so as to help teachers to complete teaching tasks to students in class.

Description

technical field [0001] The invention belongs to the field of civil (traffic) engineering teaching, in particular to a side slope and landslide demonstration device and a test method used in soil mechanics teaching. Background technique [0002] As a basic discipline of civil engineering, transportation, water conservancy and other majors, soil mechanics is playing an increasingly important role in today's era of intensified urbanization. How to use more tools to more effectively improve classroom efficiency and facilitate the explanation of key and difficult points in soil mechanics courses has become an important topic at present. [0003] Slope and landslide is one of the common geological disasters, which affects the construction of civil engineering, highway, railway and other projects. Due to the inclined surface of the slope, under the self-weight condition of rock and soil or external force, the whole rock and soil will have a tendency to slide downward, thus losing ...

Problems solved by technology

However, in the teaching process, due to the lack of relevant demonstrative experimental models, only relying on abstract theoretical lectures cannot make a complete display of slopes and landslides, making it difficult for students to master relevant knowledge content

[0004] Before the present invention, Chinese patent CN 103728435 A discloses a slope simulation test device, which is used to clarify the coupling effect of rainfall infiltration and groundwater change, but the device system is relatively huge, the cost is high, and it is inconvenient Classroom demonstrations or teaching experiments; at the same time, there is also a lack of demonstrations of the impact of slope top loads, seismic loads and other conditions on slope landslides, which are not perfect for teaching classroom demonstrations
