Problems solved by technology
[0002] In recent years, geocell retaining walls have gradually been widely used in roadbeds, slopes and other fields, but there is no systematic and clear understanding of their deformation characteristics and failure modes, and they are still in the experimental stage.
[0003] At present, although some studies have been done on different heights, slopes and loading conditions in the field of reinforced flexible retaining walls, they are not systematic and only analyze the overall situation, failing to highlight the failure mechanism of geocell retaining walls and sliding surface form, in the prior art, there is no model test that focuses on internally analyzing the different reinforcement effects of geocells with different properties, observing the overall deformation shape and reinforcement of the geocell retaining wall under different accelerations and different working conditions The deformation characteristics of the rib cell and the failure process and shape of the retaining wall provide a reference for its theoretical design, such as the geocell vegetation retaining wall disclosed in the Chinese patent application number 032190026, and the vegetation retaining wall disclosed in the Chinese patent application number 2012201347970. Geocell Stretch Composite Retaining Wall Suitable for Mining and Deformation Conditions, Chinese Patent Application No. 2008801313330 discloses a geocell for load bearing applications

Embodiment
[0069] As mentioned above, this method was used to analyze the deformation of the geocell retaining wall according to the dimensions of the model box of the centrifuge system.
[0070] Different geocell retaining wall models are established according to different working conditions, as shown in Table 1:
[0071] Table 1
[0072]
[0073]
[0074] Such as Figure 1~4 As shown, using this method to obtain their photos, position vector diagrams, displacement contour diagrams, displacement-centrifugal acceleration relationship diagrams and sliding surface diagrams, it can be seen from the photos that when the geocell retaining wall model is deformed, the maximum horizontal The displacement occurs at a position about H / 3 from the bottom of the wall, and the total displacement of the geocell retaining wall model is the largest in the fill soil near the top of the wall. Analyzing the photos of the deformation process, it can be seen that with the increase of centrifugal accele...
