[0044] Reference figure 1 This embodiment provides a sliding zone soil rheological tester 10, which includes a test box 100, a shear system 200, a reservoir water simulation system 300, and a measurement dynamic control system 400. The measurement dynamic control system 400 is set on the test box 100 It is connected to the shearing system 200, the shearing system 200 is housed in the test box 100, and the reservoir water simulation system 300 is connected to the shearing system 200 to provide the shearing system 200 with test water.
[0045] In this embodiment, a floor drain is installed at the bottom of the test box 100 to drain the water leaked during the test in a timely manner.
[0046] The cutting system 200 includes a first cutting box 210, a second cutting box 230, a normal pushing device 250, a cutting pushing device 270, and a sliding device 290. The first cutting box 210 and the second cutting box 230 are arranged opposite to each other. And they are all contained in the ...

[0064] See Image 6 This embodiment provides a sliding belt soil rheological test method, which is applied to the sliding belt soil rheological tester 10 as in the first embodiment, and is used for the sliding belt soil rheological test under the condition of long-term immersion in reservoir water. The rheological test method of slip zone soil includes:
[0065] Stakeout sealing step 601: Place the sliding soil sample in the first shear box 210 and the second shear box 230 and pass the shear seam between the first shear box 210 and the second shear box 230 The membrane is wound and sealed.
[0066] In this embodiment, the shear joint is wound and sealed with a super-elastic impermeable geomembrane to prevent water from leaking out during the test.
[0067] Sample soaking step S603: Inject water into the first shear box 210 and the second shear box 230 through the water seepage component 330. After the test water completely penetrates into the sliding soil sample and flows out of the...

[0074] See Figure 7 This embodiment provides a rheological test method for sliding zone soil, which is applied to the sliding zone soil rheological tester 10 as in the first embodiment, and is used for the rheological test of the sliding zone soil under dynamic osmotic pressure. Soil rheological test methods include:
[0075] Seepage pressure determination step S701: Obtain the change curve of hydraulic gradient with time according to the change of groundwater level in the landslide, and scale the hydraulic gradient with the time axis as the basis for determining test dynamic seepage pressure and test period.
[0076] Stakeout and sealing step S703: Place the sliding soil sample in the first shear box 210 and the second shear box 230 and pass the shear seam between the first shear box 210 and the second shear box 230 The impermeable membrane is wound and sealed.
[0077] In this embodiment, the shear joint is wound and sealed with a super-elastic impermeable geomembrane to prevent ...
