Description

technical field [0001] The invention belongs to the technical field of slope engineering, and in particular relates to a slope stability test and evaluation system and a test and evaluation method. Background technique [0002] Landslides are one of the common major geological disasters in China. According to the China Geological Hazards Network, from 1949 to 2011, more than 3,000 large-scale landslides, more than 2,000 landslides, more than 2,000 debris flows, and small and medium-sized landslides were found nationwide. There are more than 100,000 landslides, landslides, and mudslides. According to statistics: between 1951 and 1991, at least 1,169 people died due to landslides caused by human engineering activities, and the economic losses were even more immeasurable. [0003] At present, the methods of slope stability analysis mainly include numerical simulation. This method mainly simulates and evaluates the stability of slopes by establishing physical models and adjusti...

Problems solved by technology

Although the device can simulate the anti-erosion ability indoors and provide a reference for determining the slope reinforcement scheme, there are still the following deficiencies: First, the device only considers the influence of the slope surface on the overall stability of the slope. The impact of body changes on slope stability has not been considered

Second, the device only simulates the situat
