Problems solved by technology

[0004] In view of the fact that the current indoor similar simulation test phenomenon is mainly reflected by on-site photos, and it is impossible to distinguish and identify the degree and law of different vibration conditions on it, the purpose of this invention is to propose a digital image-based method for the impact of vibration on slope slippage. Characterization method, which can extract digital images of different vibration conditions in indoor similar simulation tests, and obtain the influence laws under different vibration conditions

Embodiment

[0044] In this embodiment, the method for characterizing the impact of vibration on slope slippage based on digital images is as follows:

[0045] (1) Sample collection: The soil and rock samples are kept consistent with the site to the greatest extent. In this embodiment, sand samples from the site are collected, and the slope is laid according to the proportion of the research area. The simulated slope is 80 cm long, 100 cm wide, and 33 cm high.

[0046] (2) Photo collection: In order to accurately reflect the impact of different vibration conditions on slope stability, a camera was set up 1 meter in front of the test shaking table to collect vibration photos at different stages in real time during similar simulation tests.

[0047] (3) Slip image recognition; for photos under different vibration conditions, real-time slip images were obtained through the Python image recognition program.

[0048] (4) Slip area extraction: From the identified image, the images under differen...

Abstract

The invention belongs to the field of slope stability identification, and relates to a method for characterizing the influence of vibration on slope slippage based on a digital image. The method comprises the following steps: (1) collecting a field sandy soil sample, and carrying out slope laying in proportion according to the field actual situation; (2) acquiring a real-time surface image of slope slippage under the action of vibration; (3) identifying and extracting digital images of the slope under different vibration conditions; and (4) obtaining influence rules under different vibration times and vibration frequencies. According to the method for characterizing the influence of the vibration condition on the slope slippage based on the digital image, an identification program suitable for the slippage image of the slope sample is compiled, and the slippage image identification under different vibration conditions is carried out, so that the slope slippage rule under different vibration conditions can be obtained.

Description

technical field [0001] This patent belongs to the field of slope stability identification, and relates to a method for characterizing the influence of vibration on slope slippage based on digital images. Background technique [0002] Slope stability has always been a major problem in practical engineering. At present, the main method is to use on-site geological reconnaissance and various geophysical prospecting in engineering to analyze its basic stability. Although people have realized the practical significance of slope stability for safe production, there are relatively few studies on the analysis and research of slope stability under different vibration conditions, and there is no relevant research on the use of digital images for characterization. Test apparatus and method. [0003] In the monitoring of open-pit slopes, the commonly used monitoring methods mainly include: UAV imaging, radar technology, GPS technology and GNSS technology, etc. The vibrometer collects ...
