Embodiment 1

[0045] see figure 1 as well as figure 2 , this embodiment provides a soil-rock mixed double-row pile slope failure visualization device, the visualization device includes a frame 4, a transparent model box 10, a soil-rock mixed double-row pile slope model 9, a lifting platform 2, and a rigid connecting rod 8. The height adjusting member 1 , the sheet light emitter 7 and the image system may also include a base 11 and a plurality of counterweights 3 .

[0046] The frame 4 can be placed vertically on the ground, of course, can also be placed on other plane structures, and can also be fixed by other structures. The material of the frame 4 may be aluminum alloy, or a metal material with high hardness such as stainless steel. The outer profile of the frame 4 is cuboid, and has at least two vertical rods. Certainly, in some embodiments, the frame 4 can adopt a detachable structure, so that the frame 4 can be folded up conveniently. On the one hand, it can be conveniently transpo...

Embodiment 2

[0061] This embodiment provides a soil-rock mixed double-row pile slope destruction visualization device, which adds an alarm system on the basis of Embodiment 1. Among them, the alarm system includes a displacement sensor and an alarm. The displacement sensor is installed on the frame 4 to detect the displacement of the lifting platform 2 or the rigid connecting rod 8 . The alarm is installed on the frame 4 or the lifting platform 2, and when the displacement detected by the displacement sensor exceeds a preset displacement, an alarm message is sent. In this way, when the lifting range of the lifting platform 2 is too large, the alarm device can give an alarm in real time to remind the operator, ensure the progress of the test, and protect the visualization device at the same time.

Embodiment 3

[0063] This embodiment provides a synthetic transparent soil, and the synthetic transparent soil is used in conjunction with the soil-rock mixed double-row pile slope damage visualization device in Embodiment 1 or Embodiment 2. The synthetic transparent soil includes transparent soil and pore liquid. Based on factors such as the similarity rate of the model test and the clarity of the speckle field, the material selected for transparent soil is fused silica sand. cm 3 , while the minimum dry density is 0.907g / cm 3 . At the same time, the soaking liquid is a mixture of n-dodecane and 15# white oil in a mass ratio of 1:4. When preparing transparent soil, select fused silica sand with the above particle size, clean them and dry them. This removes impurities and moisture from the material. Under the indoor temperature environment (25°C), the pore liquid was prepared, and the refractive index of the pore liquid was measured to be 1.4585 by using a 2WAJ Al refractometer. While...

Abstract

The invention discloses a soil-rock mixed double-row pile slope destruction visualization device and method. The soil-rock mixed double-row pile slope destruction visualization device comprises a frame, a transparent model box, a soil-rock mixed double-row pile slope model, a lifting platform, a rigid connecting rod, a height adjustment piece, a sheet light emitter and an image system; the transparent model box is internally loaded with soaking liquid the same as the soil-rock mixed double-row pile slope model in refractive index; the height adjustment piece can drive the lifting platform to ascend and descend in the vertical direction of the frame so as to drive the rigid connecting rod to downwards press the soil-rock mixed double-row pile slope model; the image systems comprises a PIV digital image collecting mechanism and an industrial camera; and the industrial camera is used for collecting three-dimensional image information, and the PIV digital image collecting mechanism records displacement of internal particles in real time according to the three-dimensional image information and generates destruction images and data. The internal deformation condition of the soil-rock mixed double-row pile slope model is obtained, the destruction images and data are obtained, and the visualization function of slope destruction is achieved.

Description

technical field [0001] The present invention relates to a visualization device in the field of civil engineering rock and soil test technology, in particular to a soil-rock mixed double-row pile slope destruction visualization device, and also relates to a soil-rock mixed double-row pile slope based on transparent soil of the visualization device Broken visualization method. Background technique [0002] In the field of geotechnical engineering simulation experiments at this stage, soil-rock mixed double-row pile slopes have become a relatively common slope form in engineering, and the failure of mixed slopes has become increasingly prominent. hot topics. Therefore, it is particularly important to obtain real-time and reliable real-time internal deformation of the soil-rock mixed double-row pile slope model, and to realize the displacement visualization of the soil-rock mixed double-row pile slope under the action of the top load. [0003] The traditional indoor model test...
