Similar simulation experimental model and laying method thereof

Abstract

The invention relates to a similar simulation experimental model and a laying method thereof. The experimental model comprises an experimental model body, the experimental model body is composed of a plurality of combined block layers sequentially arranged in the longitudinal direction and a filling material, and each combined block layer is composed of a plurality of combined block bodies which are sequentially arranged in the left-right direction. The filling material fills gaps among all the combined block bodies in the experimental model body. Each combined block body is composed of an anti-tensioning pull rod located in the middle, a front framework block fixedly connected to the front end of the anti-tensioning pull rod and a rear framework block fixedly connected to the rear end of the anti-tensioning pull rod. The method comprises the following steps of: preparing enough combined block bodies; laying a bottom similar material on an experimental table; sequentially laying layers of similar material from bottom to top; carrying out a similar simulation experiment; and recovering the combined block bodies. The model can be prefabricated in advance and can be effectively used in similar simulation experiments for many times. According to the method, the laying method is simple, the construction steps are few, and the problem of lateral collapse in the laying and experiment period is thoroughly solved.

Description

technical field [0001] The invention belongs to the technical field of indoor physical similar simulation experiments, and in particular relates to a similar simulation experiment model and a laying method thereof. Background technique [0002] As an important discipline in the field of civil engineering, geotechnical engineering involves increasingly complex problems. It is difficult to solve the problems encountered in engineering practice only through theoretical analysis, so corresponding experiments must be carried out to verify the analysis. A better simulation effect can be achieved through similar simulation experiments. [0003] Similarity simulation experiment is an inevitable product of social development. Similarity simulation experiment makes a model of a certain size according to the corresponding similarity principle by comparing the on-site stratum, etc., and then imitates the actual operation on the site to excavate and pressurize the model to observe the mo...

Problems solved by technology

[0004]Similar simulation experiments need to make test benches, observation devices, similar simulation materials, etc., and the most important thing is to make similar simulation experiment models. Most of the current indoor physical similar simulation experiments All use similar simulation experimental models for one-time use, that is, similar models are made by mixing sand, lime, etc. according to a certain ratio, but this traditional similar simulation model has considerable limitations:

[0005]First of all, the preparation process of traditional similar simulation materials is relatively complicated, and traditional similar materials are prone to lateral collapse during the experiment process, which will affect the progress of the experiment. At the same time, the production Similar simulation materials will take up a lot of time and will waste the precious time of a large number of researchers; the traditional similar simulation system is time-consuming and labor-intensive, whether it is laying at the beginning of the experiment or dismantling after the end of the experiment, which seriously affects the progress of the experiment and research efficiency

[0006]Secondly, the consumption of proportioning materials used in the traditional similar simulation model is relatively large. They are all treated as experimental waste, which not only wastes resources and increases economic costs, but the most important thing is to cause certain environmental pollution and bring certain environmental protection problems.

[0007]Finally, the materials in the traditional similar simulation model are made of sand, lime and other materials. Due to the influence of the scientific nature of the ratio and other issues, some materials may not meet the experimental requirements.
