Slope model test system based on lever loading

Abstract

The invention relates to a slope model test system based on lever loading. The system comprises a slope model test box, a lever loading device, a force application frame and a loading plate; the slopemodel test box is arranged on the indoor flat ground; the slope model test box is a cuboid box with an open top; the lever loading device is fixedly mounted at the top of the slope model test box; the right side edge of the inner bottom of the slope model test box is rotationally connected with a slope panel; the loading plate is horizontally placed on the upper surface of a slope soil sample; abearing plate is placed on the upper surface of the loading plate and is in compression joint with the loading plate; the bearing plate is located below the lever loading device; and the force application end of the lever loading device downwards abuts against the top of the bearing plate. The test system is scientific in design, convenient to operate, easy to implement and more stable in loading,conforms to the actual physical characteristics of slope deformation and damage, can consider the influence of the slope angle on the slope stability, and can more conveniently and visually researchthe stress mechanism and the damage process of an anti-slide pile in a laboratory.

Description

technical field [0001] The invention belongs to the technical field of side slope tests, and in particular relates to a side slope model test system based on lever loading. Background technique [0002] In recent years, my country's economy has developed rapidly. With the rise of the Central Plains Economic Zone to the national strategy, the construction of highway projects in the western mountainous areas of Henan Province has gradually accelerated. The terrain and geological conditions in the western region are complex, and the problem of large and medium-sized landslides is particularly prominent. The management of landslide disasters is currently Anchor cables, anchor rods, and anti-slide piles are mostly used. However, for large-scale landslides with complex geological conditions and deep sliding surfaces, anti-slide piles can provide greater protection due to their small disturbance to the slope and excellent bending resistance. Therefore, it is widely used in the preven...

Problems solved by technology

In the model test, how to accurately simulate the landslide thrust is the key factor to ensure the accuracy of the test. The test conditions of the large centrifuge are very demanding, and the test site is limited and the cost is high.

It is difficult for the existing jack loading device to
