Abstract
Provided is a three-directional motion decoupling periodic structure for a shaking table container. The periodic structure is formed by sequentially superimposing n periodic structure units, wherein each of the periodic structure units is formed by sequentially superimposing a first side-confining layer, a planar decoupling layer, a second side-confining layer and an elastic layer, wherein n is a positive integer greater than or equal to 2; the cross-sectional shapes of the first side-confining layer, the elastic layer, the second side-confining layer and the planar decoupling layer are the same; and the periodic structure is used for implementing three-directional motion decoupling in the operating condition of ground shaking. Further provided is a three-directional motion decoupling container for shaking table test, which is formed by combining the periodic structure, a container base plate and a position-limiting protection door-type frame (). The container, which is light in weight and high in strength, is applicable to the shaking table tests at hypergravity and normal gravity. Multiple measures are taken to ensure the motion synchronization between the container and tested soil, the non-interference of the motions of the container and the tested soil in the three directions of X, Y and Z, no extra acting force being exerted on the tested soil by the container, and the avoidance of a boundary effect as much as possible, so as to fully realize the three-directional decoupling and reconstitute original site characteristics.
