Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] like Figure 1 The simulation method for the visualization of foundation structure and soil movement in soil under earthquake action can be realized by the following technical steps:

[0020] (1) Make soil model box (7) (30cm×10cm×30cm), the model box is made of high-strength transparent glass

[0021] (2) Configure transparent soil with a certain density control (2), use fused silica particles with a particle size of 1-3mm, and use a certain concentration of CaBr for the pore liquid 2 solution,

[0022] (3) drive into the model pile (6) at the central position of the transparent soil body (2), and the model pile (6) can be made with plexiglass,

[0023] (4) Place the soil model box (7) fixed with model piles (6) on the vibration table,

[0024] (5) Place the fan laser generator (1) (532nm green laser) on the side of the transparent soil mode...

Abstract

The invention discloses a simulation method for a base structure in a soil body and the movement visualization of the soil body under an earthquake action, and belongs to the field of rock and soil test mechanics. Moving and laser speckles of transparent soil and a model pile (6) in a transparent soil model box (7) positioned on a vibration table (3) under the irradiation of a fan-shaped laser generator (1) are shot by utilizing a high-speed digital camera (4), and the strain of movement of transparent soil particles is obtained through a computer processing system, so that the movement and the deformation of a pile foundation model are obtained.

Description

technical field [0001] The invention belongs to the technical field of rock and soil test mechanics, and in particular relates to a simulation method for visualization of foundation structure and soil movement in soil under earthquake action Background technique [0002] In geotechnical engineering, since structures such as anchors, foundations and geotextiles are usually embedded in the soil and are invisible to the naked eye, researchers have used CT, X-ray imaging methods, nuclear magnetic resonance and other methods to achieve Visualization of structures in soil and nearby soil. However, the equipment in these methods is relatively expensive, and it is difficult to popularize and apply. Here, an economical and feasible simulation method for realizing the visualization of foundation structure and soil movement in soil under earthquake action is proposed. technical field [0003] According to different soils, transparent granular materials such as silica gel particles...
