Embodiment 1

[0024] exist Figure 1~5 Among them, the soil consolidation subsidence instrument of the centrifugal model test device of the present embodiment consists of a model box 1, a model box beam 2, a guide sleeve 3, a guide rod 4, a laser displacement sensor 5, an air pipe 6, a reaction force frame 7, and a computer 8 , stud 9, sample bucket 10, inflation nozzle 11, filter paper 12, drainage plate 13, load plate 15, rubber belt 16, adjusting screw rod 17, sample bucket rack 18 are connected to form.

[0025] On the side wall in the model box 1, the sample bucket rack 18 is fixedly connected with the adjusting screw rod 17. By adjusting the adjusting screw rod 17, the sample bucket rack 18 is adjusted to the center position of the model box 1, and the center of the sample bucket rack 18 The position is processed with a circular hole, and the sample bucket 10 is placed in the circular hole at the center of the sample bucket rack 18. The ratio of the diameter to the height of the sampl...

Embodiment 2

[0027] In this embodiment, the diameter-to-height ratio of the sample barrel 10 is 3.99; the diameter of the permeable holes a processed at the bottom of the sample barrel 10 is 0.4mm, and the permeable holes a are evenly distributed on different diameters of the equally divided circle. The drainage plate 13 is uniformly processed with 12 circles of circular groove b drainage grooves with different diameters and 3 straight grooves c drainage grooves arranged along the diameter direction, and the two outer ends of the 3 straight grooves c drainage grooves. Radial processing is provided with the drainage hole that communicates with the straight groove c drainage groove. Other components and the coupling relationship of the components are the same as in Embodiment 1.

Embodiment 3

[0029] In this embodiment, the diameter-to-height ratio of the sample barrel 10 is 4.0; the diameter of the permeable holes a processed at the bottom of the sample barrel 10 is 0.8 mm, and the permeable holes a are evenly distributed on different diameters of the equally divided circle. The drainage plate 13 is uniformly processed with 6 circles of circular groove b drainage grooves with different diameters and 6 straight grooves c drainage grooves arranged along the diameter direction, and the two outer ends of the 6 straight grooves c drainage grooves. Radial processing is provided with the drainage hole that communicates with the straight groove c drainage groove. Other components and the coupling relationship of the components are the same as in Embodiment 1.

Abstract

The invention discloses a soil consolidation settlement meter of a centrifugal model testing device, a sample bucket rack is arranged on the inner side wall of a model box, a sample bucket is arranged on the sample bucket rack, a water penetrating hole a is arranged in the bottom of the sample bucket, a drain plate provided with a drain tray is arranged on the outer surface of the bottom of the sample bucket, the sample bucket is internally provided with sample soil to be tested, on filter paper, the upper surface of the sample soil is provided with a bearing plate, a rubber tape is arranged on the bearing plate, an air charging connector connected with an air pipe is arranged on the rubber tape, the upper surface of the rubber tape is provided with a counter-force frame provided with a guide sleeve, the guide sleeve is internally provided with a guide rod linked with the bearing plate, the top of the model box is provided with a model box cross beam, and a displacement sensor connected with a computer is arranged on the model box cross beam through a lead. The soil consolidation settlement mete provided by the invention has the advantages of wide application range, accurate test data, capabilities of overcoming the friction force on the side wall, discharging water during the soil consolidation smoothly and simulating the gradual change of an additional load of the soil body,and the like, and can be used for testing the consolidation of the soil body.

Description

technical field [0001] The invention belongs to the technical field of testing the consolidation characteristics of saturated soil by mechanical stress, and in particular relates to a device for performing soil consolidation tests using a centrifuge. Background technique [0002] The soil is composed of the skeleton body composed of soil particles and the pores between the skeletons. The compression deformation of the foundation soil, the settlement deformation and stability of the embankment are all caused by the compression of the soil skeleton and the change of the void ratio. Both are related to time and are a deformation process. Saturated soil or partially saturated soil is under the action of load, the stress state of the soil changes, the internal water slowly seeps out, and the volume of the soil gradually compresses, and the applied pressure is transferred from the pore water to the soil skeleton accordingly, until the deformation reaches The whole process of soil...
