Abstract

The invention belongs to the technical field of geotechnical engineering model test equipment. The proposed geotechnical engineering anti-explosion structure model test device is composed of a side-limited box body and an explosion pit at the lower part, and is equipped with a matching wave-eliminating mechanism, a locking mechanism and a sliding Positioning mechanism; wave dissipation mechanism includes aluminum wave dissipation grid (21) and wooden wave dissipation plate (20); sliding positioning mechanism includes two-way jack cylinder (15), guide rail (17) and limit block (19); locking The mechanism is composed of a locking pull rod (3), a side limit connecting block (18) and a nut (2). The invention can simulate different explosion forms in equipment with moderate size; meet the convenient and feasible requirements for excavation of caverns, installation of enclosure structures and measurement equipment; it can be reused, and it is beneficial to observe the damage of structures in the test; The results can provide an important basis for underground explosion-resistant engineering design and scientific research.

Description

technical field

[0001] The invention belongs to the technical field of geotechnical engineering model test equipment, and mainly proposes a model test device for an anti-explosion structure of geotechnical engineering. Background technique

[0002] Due to the importance of structural anti-knock performance, many scholars at home and abroad have carried out related research. The following is a brief description of representative research abroad and domestically:

[0003] Example 1: Charles E.Joachim et al. of the United States conducted model tests on the impact of the explosion load density and the thickness and strength of the rock mass protective layer on the external damage of the tunnel caused by the accidental explosion of the underground explosive depot, and the degree of damage caused by the air shock wave and debris caused by the explosion. Were studied.

[0004] The geometric scale of the model test is 1:25, the channel of the underground explosive storage model is...
