Abstract

The invention relates to an anti-sliding pile-reinforced slope visualization model test device and method and belongs to the technical field of geotechnical engineering and geological engineering. The device mainly comprises a molding box, a slope molding device, a loading device, transparent soil, anti-sliding piles, laser launchers and digital cameras. The molding box is a transparent box having four organic glass sides. The transparent soil slope and the anti-sliding piles are arranged in the box. The loading device is fixed to a loading machine and applies load to the top of the slope. The laser launchers are respectively arranged in left and right sides of the molding box. The digital cameras are respectively arranged on the top view surface and the front view surface of the molding box and are used for taking clear images of the top and side of the box. Compared with the existing test device and method, the test device and method provided by the invention realize visual observation of anti-sliding pile deformation, replacement of soil beside the pile and formation and damage of the soil arch between piles, have high measurement accuracy and strong repeatability, and can be widely used for research of the mechanism of slope anti-sliding pile deformation-caused internal damage.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering and geological engineering, and relates to a model test device and a test method, in particular to a visual model test device and a test method for slope reinforcement with anti-slide piles. Background technique [0002] Landslide disasters frequently occur in the mountainous areas of western my country, seriously threatening the lives and property safety of local people, so the prevention and control of landslides is particularly important. There are many kinds of landslide disaster control measures. At present, 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 have less disturbance to the slope and It has excellent bending resistance and can provide greater resistance, so it is widely used in the prevention and treatment of landslides, and in the case...
