Problems solved by technology
Due to the huge size and high kinetic energy of the sliding body, it is difficult to control the risk of damage. For example, the full-scale rainfall landslide test in Japan in 1971 caused 15 deaths and 11 injuries in a major accident
In addition, recovery at the later stage of the test requires a large investment of manpower and financial resources, and the test is not repeatable

Embodiment 1
[0051] Embodiment 1: The landslide power device is a jack.
Embodiment 2
[0052] Embodiment 2: The landslide power device, that is, the power device for landslide drills, includes double-layer airbags and an inflation and deflation system. The inflation and deflation system is used to control the inflation and deflation of the double-layer airbags.
[0053]The double-layer airbag is arranged under the movable steel plate, and the movable steel plate can slide along the arc surface in the recovery tank, and the sliding angle is 0-50°, preferably 49.7°.
[0054] The recovery trough also has a slope that limits the sliding angle of the movable steel plate, and the movable steel plate is hinged with the support at the bottom of the slope or the foundation at the bottom of the slope.
[0055] One end of the double-layer airbag is anchored on the support at the bottom of the slope or the foundation at the bottom of the slope, and the anchor point 73 is preferably located directly below the hinge point 31 .
[0056] Such as image 3 As shown, the double-l...

Abstract
The invention discloses a landslide simulation test device for flood control and rescue drills, which comprises a fixed steel plate, a drainage filter pipe, a pressurizing device, a movable steel plate, a slope top support, a slope bottom support, a landslide power device and a recovery tank; the fixed steel plate is inclined It is fixedly installed, and the slope ratio is 1:1; several drainage filter pipes are buried on the fixed steel plate; the movable steel plate can rotate under the drive of the landslide power device; the recovery tank is a conical tank with a fan-shaped cross section, and the recovery tank includes arc Surface, inclined surface and vertical side retaining surface; the included angle between the inclined surface and the horizontal plane is 49~50°. The invention can realize landslide danger on the spot, and carry out emergency drills of engineering measures such as embankment crest load reduction, embankment foot ballasting, etc. during the occurrence and development of landslides, and risks are controllable during the emergency drill process without causing casualties. At the same time, the prototype landslide model can be quickly restored after the drill, which saves a lot of manpower, material and financial resources for later maintenance, and the test is repeatable.
Description
technical field [0001] The invention relates to the technical field of geotechnical engineering and disaster prevention and mitigation model tests, in particular to a landslide simulation test device used for flood control and rescue drills. Background technique [0002] With the impact of global climate change, extreme weather is showing a trend of frequent occurrence and reoccurrence. In recent years, the Yangtze River Basin, Pearl River Basin, and Taihu Lake Basin in China, including the Second Songhua River Basin in Northeast my country and the Haihe River Basin, have experienced excessive floods. Many landslides of dykes and dams have occurred, and emergency rescue is required after the landslide occurs. However, due to lack of training, the rescue often has a certain degree of blindness. Therefore, it is of great significance to understand the hazards of landslides and carry out targeted rescue drills to improve the effectiveness of landslide rescue. [0003] The exist...
