A model test device for pipeline safety in landslide area

Abstract

The invention relates to the field of geotechnical engineering, in particular to a model test device for pipeline safety in a landslide area. It includes a preparation system, a rainfall simulation system and a loading system. The preparation system is used to hold and prepare samples for the entire test. The rainfall simulation system is used to simulate rainfall. The loading system uses hydraulic jacks to homogenize similar material samples in the preparation system Loading to simulate in-situ stress loading. The invention provides a model test device for pipeline safety in a landslide area. The preparation system of the device can simulate different slope heights and different slopes by changing the number of splicable side panels, replacing strip-shaped control panels with different inclination angles, or precipitation by precipitation nozzles. The impact on the safety of the pipeline at the bottom of the slope when the landslide slides down at the angle or rainfall is not affected by the test position, which can meet the needs of different sites and can be used for large-scale three-dimensional physical model tests.

Description

technical field [0001] The invention relates to the field of geotechnical engineering, in particular to a model test device for pipeline safety in a landslide area. Background technique [0002] Landslide refers to the overall sliding caused by shearing along a certain weak surface (or weak zone) inside the slope under certain natural and geological conditions, the part of the rock and soil mass that constitutes the slope, under the action of gravity. destroy. The occurrence of landslides is usually sudden, frequent and destructive, and it is a large-scale natural disaster recognized by the world. The pipelines laid at the bottom of the slope may be deformed or even bent and fractured by the sliding body, resulting in serious consequences. [0003] At present, the separate researches on pipelines and landslide disasters are relatively comprehensive, and the combination of the two is seldom studied, and it is impossible to deeply understand the influence of landslides on th...

The pipeline laid at the bottom of the slope may be deformed or even bent and broken due to the sliding of the sliding body, causing serious consequences

[0003] At this stage, separate studies on pipelines and landslide disasters are relatively comprehensive, and there are few studies on the combination of the two. It is impossible to deeply understand the influence of landslides on pipeline laying under different slope angles, different slope heights, or rainfall.
