Embodiment 1

[0046] Step 1: First make a sandbox 1, one group of facing surfaces of the sandbox 1 is plexiglass 1-3, and the other surface is a wooden board 1-4, secondly, select sand samples from the aeolian sand area and lay them on the bottom of the sandbox first Gravel layer 2-9, lay sand layer 2-1 on the gravel layer 2-9, and then adopt layered compaction method to lay aeolian 2-4 sand layer by layer, and aeolian sand 2-4 Tamping, control the degree of compaction and water content, use L-shaped baffles 2-10 to assist slope compaction, first make the model into a ladder shape, and then use cutting to cutting to form, the slope with wrapping layer is made using two The method of filling and cutting is formed. After the embankment is filled for the first time, the excess sand is cut off, and the edge wrapping material is added for filling and compaction for the second time, and the excess edge wrapping layer material is cut off. slope forming;

Embodiment 2

[0053] Step 1: First make a sandbox 1, one group of facing surfaces of the sandbox 1 is plexiglass 1-3, and the other surface is a wooden board 1-4, secondly, select sand samples from the aeolian sand area and lay them on the bottom of the sandbox first Gravel layer 2-9, lay sand layer 2-1 on the gravel layer 2-9, and then adopt layered compaction method to lay aeolian 2-4 sand layer by layer, and aeolian sand 2-4 Tamping, controlling the degree of compaction and water content;

[0054] Step 2: set waterproof sponge 2-3 on the side of plank 1-4, the surface layer of waterproof sponge 2-3 is covered with plastic film 2-2, and set scale 5 outside plexiglass 1-3 and plank 1-4;

[0055] Step 3: Mark the filling thickness of each layer and the outline of the slope slope on the plexiglass 1-3, and fill each layer of filling materials in layers according to the drawn lines, with clay-bound edges Draw the contour lines of the aeolian sand and the edged clay on the side slope, and fil...

Embodiment 3

[0060] 1. Design and production of model box

[0061] (1) This test uses a rigid model box with three sides closed and one side open. The size of the model box is about 1960*1700*800 (length*width*height). The frame is made of 40*3 equilateral angle steel, and 20mm thick Plexiglass, and a 20mm thick composite wood board is installed on the other side; 100*100*3 (length*width*height) type H steel is used as the base, and 2mm thick steel plates are laid on the base, and small steel plates are welded vertically and unevenly on the steel plate The purpose is to increase the friction between the embankment model and the box base; the model box base and the vibration table are connected by bolts, and the base H-shaped steel is cut with openings for fixing bolts. In order to prevent the frame from deforming during hoisting, transportation and vibration of the model box, reinforcing ribs are added on the upper part of the model box and on the wall of the wooden box, and the reinforcin...

Abstract

The invention discloses a device for analyzing the stability of an embankment under the effect of an earthquake load and a manufacturing method of the device. The device comprises a sand box and an embankment model, wherein the sand box can be connected with a vibration table, the embankment model is arranged in the sand box, tracking particles and a scaleplateare are arranged outside organic glass and wood plates of the sand box, and the length of the lower layer wind accumulation sand in the wind accumulation sand of adjacent layers of the embankment model is greater than that of the upper layer wind accumulation sand, so that a side slope is formed, the embankment model is provided with a plurality of acceleration sensors, a soil pressure sensor and a displacement sensor, the tracking particles arranged on the three side surfaces of the sand box are respectively and correspondingly provided with supplementing light sources and cameras, the three cameras are respectively connected with a computer data collecting control table, organic glass plates are used at the two sides of the sand box, and further, the test phenomenon can be more easily observed. In order to reduce the weight of the sand box and to void the waste of test resources, a composite wood plate is used at one side of the sand box, the use requirements are met, meanwhile, the weight of a box body is reduced to the maximum degree, the test and the transportation are convenient, and the vibration efficiency of the vibration table is improved.

Description

technical field [0001] The invention belongs to the field of special equipment, and in particular relates to a device and a manufacturing method for analyzing the stability of an embankment under an earthquake load. Background technique [0002] my country is a country with many deserts. Deserts (lands) are mainly distributed in nine provinces including Xinjiang, Gansu, Inner Mongolia, Ningxia, Qinghai, Jilin, Liaoning, Shaanxi and Heilongjiang. The most famous deserts are: the Taklimakan Desert in the Tarim Basin of Xinjiang, the Gurbantunggut Desert in the Junggar Basin, the Tengger Desert in Inner Mongolia, the Badain Jaran Desert, the Qaidam Basin Desert in Qinghai, Shaanxi, Ningxia and Inner Mongolia The area is bordered by the Mu Us Desert and so on. Because desert areas are mainly distributed in remote areas in the west. The area is vast, with few people and barren land. Therefore, the roads before the 1980s mainly served the transportation and communication of peo...
