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

[0043] Embodiment 1: The landslide power device is a jack.

Embodiment 2

[0044] 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.

[0045] 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°.

[0046] 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.

[0047] 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 .

[0048] Such as image 3 As shown, the double-...

Abstract

The invention discloses a landslide simulation test method for flood prevention and emergency drilling. The method comprises the steps of step 1, building of a landslide simulation test device, step 2, construction of a landslide model, step 3, saturation of an earth material, step 4, landslide simulation test, wherein a horizontal locking state of a movable steel plate is relieved, a part of earth material located above the movable steel plate slides into a recovery tank along the cambered surface of the recovery tank and the upper surface of the movable steel plate to form a landslide; a slope body after sliding down is a sliding-down slope body, the outer slope ratio of the sliding-down slope body is 1:0.7; step 5, landslide flood prevention and emergency drilling, and step 6, restoration of the landslide model. The landslide simulation test method for flood prevention and emergency drilling has the advantages that a landslide dangerous circumstance can be achieved on site, emergency drilling of levee crown deloading, levee foot ballasting and other engineering measures is carried out during landslide occurrence and development, and the risks are controllable during emergency drilling, thereby not causing casualties; the landslide model can be rapidly restored after drilling is completed, the manpower, material resources and financial resources of later maintenance are greatly saved, and the test has repeatability.

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 method 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...
