Abstract

The invention discloses a three-directional shearing model box device. The device comprises a steel plate and multiple framework layers mounted above the steel plate. The framework layers comprise multiple layers of frameworks, rubber dies arranged on the inner sides of the frameworks in a riveting manner, supporting units mounted between the framework layers, and columns mounted on the periphery of the steel plate. The frameworks are made of light aluminum alloy materials. The frameworks are parallelly arranged at equal vertical intervals. The columns are arranged on the periphery of a shearing model box at equal intervals, so that the shearing model box can freely move in three directions when inputting three-directional seismic excitation, and ultra-displacement, jumping and shedding phenomena during a test of the shearing model box can be avoided. The frameworks are made of aluminum alloy H-section steel, so that the weight of the shearing model box is reduced, and the influence on the whole model by the framework weight can be reduced. The aluminum alloy H-section steel frameworks have enough rigidity, so that the model soil is zero in lateral strain in the horizontal direction, and the aluminum alloy H-section steel frameworks can maintain original states after the seismic motion excitation.

Description

Technical field

[0001] The invention belongs to the technical field of civil engineering, and relates to a three-way shear model box device used for the shaking table test of a non-base rock nuclear power plant structure. Background technique

[0002] It is necessary to consider the dynamic interaction of soil-structure in the shaking table test of non-bedrock nuclear power plant model. Therefore, a container-shear model box containing soil must be provided, because the shear model box can eliminate the boundary effect. The main structure of the nuclear power plant belongs to Class I items must consider the response of multiple layers of mutually perpendicular horizontal directions and a vertical earthquake. The connection between the layers of the traditional layered model box can only be in the horizontal direction or a single horizontal direction. Moving, the shear model box cannot move freely in three directions when the three-way seismic excitation is input, thereby affectin...
