Embankment filling device for geotechnical centrifugal model test
The invention discloses an embankment filling device for a geotechnical centrifugal model test, which comprises a sand box fixed above a model box, a plurality of partition bins corresponding to the size of an embankment model are arranged in the sand box, and the bottom of the sand box is provided with an upper layer pore plate, a middle layer pore plate and a lower layer pore plate which are sequentially arranged from top to bottom; the upper-layer pore plate and the lower-layer pore plate are both of a fixed structure, the middle-layer pore plate is of a push-pull sliding structure and is driven by a hydraulic cylinder, when the middle-layer pore plate is in an initial state, the middle-layer pore plate is staggered from sand leakage holes of the upper-layer pore plate and the lower-layer pore plate, and when the middle-layer pore plate is in an initial state, sand leakage holes of the middle-layer pore plate are staggered from sand leakage holes of the lower-layer pore plate. And when the middle-layer pore plate is pulled out to a set position, the middle-layer pore plate is aligned with the sand leakage holes of the upper-layer pore plate and the lower-layer pore plate. Dynamic filling of embankment models with different heights, different sizes and different gradients can be achieved in the high-acceleration environment, and simulation of the embankment model filling process is completed under the condition that a centrifugal machine is not stopped.
本发明公开了一种用于土工离心模型试验的路堤填筑装置，包括固定在模型箱上方的砂箱，在所述砂箱内设有与路堤模型尺寸对应的多个分隔仓，所述砂箱的底部为从上至下依次设置的上层孔板、中层孔板和下层孔板，所述上层孔板和所述下层孔板均采用固定结构，所述中层孔板采用推拉滑动结构，所述中层孔板采用液压缸驱动，当所述中层孔板处于初始状态时，所述中层孔板与所述上层孔板和所述下层孔板漏砂孔错开，当所述中层孔板拉出至设定位置时，所述中层孔板与所述上层孔板和所述下层孔板漏砂孔对齐。本发明可以在高加速度环境中实现不同高度、不同大小、不同坡度路堤模型的动态填筑，在离心机不停机的情况下，完成路堤模型填筑过程的模拟。
