Description

Technical Field

[0001] The invention belongs to the technical field of geotechnical engineering, and in particular relates to a remote landslide sliding distance measuring device used for model tests. Background Art

[0002] Slopes are a common type of terrain in urban construction, transportation, and water conservancy and hydropower engineering. With the rapid development of various types of construction projects, landslide disasters are becoming more and more frequent, causing serious losses. Therefore, the deformation and instability mechanism and sliding distance of slopes have always attracted the attention of scholars in the field of geotechnical engineering. Due to the constraints of test sites, test funds and technical conditions, the current research on slope instability and sliding distance is mainly carried out through numerical simulation, indoor tests and physical simulation methods. In physical simulations such as large-scale earthquake simulation shaking table tests, due to the limitations of the model box size, it is very difficult to achieve the actual distance of slope sliding, and there is a boundary effect on the baffle at the foot of the slope model during the vibration process, which greatly restricts the research work on slopes in the field of geotechnical engineering. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a remote landslide sliding distance measurement device and method for model test, which solves the problem that the current model test cannot meet the requirements of slope sliding distance measurement.

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: a remote landslide sliding distance measurement device for model test, composed of a rigid closed model box, two groups of shock-absorbing strips and a sliding distance measurement model box, a large earthquake simulation vibration table top is fixed to the bottom of the rigid closed model box, connecting holes are arranged on both sides of the shock-absorbing strips, a pulley is arranged at the bottom of the sliding distance measurement model box, a baffle is arranged on the side of the sliding distance measurement model box, a hanging ring is arranged on the baffle, a ruler is arranged around the sliding distance measurement model box, threaded holes are arranged on the side of the rigid closed model box, the outer ends of the rigid closed model box and the sliding distance measurement model box are arranged as bolt assemblies matching with the shock-absorbing strips, and table covers are arranged on both sides of the large earthquake simulation vibration table top.

[0005] The rigid closed model box and the sliding distance measurement model box are connected to the shock absorbing strip through a bolt assembly.

[0006] The pulley slides on the vibration table surface and the table cover.

[0007] The sliding distance measurement model box is provided with scales around it.

[0008] Compared with the prior art, the present invention is beneficial in that it can effectively reduce human errors and limited experimental equipment so that the length of the slope model meets the experimental requirements, and has the advantages of directly measuring the slope sliding distance and protecting the test equipment.

[0015] The present invention is described in detail below in conjunction with specific embodiments:

[0016] It consists of a rigid closed model box 3, two groups of shock-absorbing strips 4 and a slip distance measurement model box 5, a large earthquake simulation vibration table top 2 is fixed to the bottom of the rigid closed model box 3, connecting holes 41 are arranged on both sides of the shock-absorbing strips 4, a pulley 54 is arranged on the bottom of the slip distance measurement model box 5, a baffle 52 is arranged on the side of the slip distance measurement model box 5, a hanging ring 53 is arranged on the baffle 52, a scale 51 is arranged around the slip distance measurement model box 5, threaded holes 31 are arranged on the side of the rigid closed model box 3, the outer ends of the rigid closed model box 3 and the slip distance measurement model box 5 are arranged as bolt assemblies matching with the shock-absorbing strips 4, and table covers 1 are arranged on both sides of the large earthquake simulation vibration table top 2.

[0017] The rigid closed model box 3 and the slip distance measurement model box 5 are connected to the shock absorbing strip 4 through a bolt assembly.

[0018] The pulley 54 slides on the vibration table surface 2 and the table cover 1 .

[0019] The sliding distance measurement model box 5 is provided with scales 51 around it.

[0020] like Figures 1 to 5A remote landslide sliding distance measuring device for model testing is shown, comprising a rigid closed model box 3, two sets of shock-absorbing strips 4, and a sliding distance measurement model box 5. A large earthquake simulation vibration table 2 is fixed to the bottom of the rigid closed model box 3, and connecting holes 41 are provided on both sides of the shock-absorbing strips 4. A pulley 54 is provided at the bottom of the sliding distance measurement model box 5. The pulley 54 at the bottom of the sliding distance measurement model box slides on the vibration table 2 and the table cover 1. A baffle 52 is provided on the side of the sliding distance measurement model box 5, and a hanging ring 53 is provided on the side baffle of the sliding distance measurement model box. A scale 51 is provided around the sliding distance measurement model box. The outer ends of the rigid closed model box 3 and the sliding distance measurement model box 5 are both provided with bolt structures that match the shock-absorbing strips 4.

[0021] As the preferred connection method between the rigid closed model box 3 and the slip distance measurement model box 5, the rigid closed model box 3 and the slip distance measurement model box 5 are connected to the shock absorbing strip 4 by bolts. This connection method has the advantages of reducing the collision and boundary friction between the two model boxes. The three are installed and fixed by bolt holes, which is convenient for disassembly during the test.

[0022] The slip distance measurement model box 5 slides on the vibration table surface 2 and the table cover 1 through the bottom pulley 54. This arrangement reduces the influence of friction resistance on the test results during the test.

[0023] When using this equipment, first, slide the vibration table cover 1 to both sides before the test, fix the rigid closed model box 3 on the vibration table surface 2 with bolts, and remove the baffle at one end of the rigid closed model box 3. After the preparation is completed, the sliding distance measurement model box 5 can be installed, and the sliding distance measurement model box 5 is placed on the vibration table cover 1 and the surface 2, and the shock absorbing strip 4 is placed between the rigid closed model box 3 and the sliding distance measurement model box 5. The bolt holes between the three are at the same level through the fixing bolts. Finally, fix all the equipment with bolts.
