Soft intercalated layer-containing side slope model and forming deformation monitoring method

Abstract

The invention discloses a soft intercalated layer-containing slope model and a forming deformation monitoring method. The soft intercalated layer-containing slope model forming comprises a cylindrical iron block, a guide rail, an upper model soil body, an air guide pipe, an air compressor, a rubber sleeve, a rubber membrane, a soft intercalated layer, a deformation sensor, a needle cylinder, a grouting pipe, filter paper, a soil nail, a side plate, a lower model soil body and a bottom plate. The rubber sleeve is transparent and hollow and is arranged in an interlayer between the upper model soil body and the lower model soil body, high-pressure gas is injected through the air compressor, and the rubber sleeve is used for observing whether the surface of the soil body is flat or not. The needle cylinder is provided with scales, quantitative grouting to the interlayer is achieved through the rubber membrane with an opening in the middle, used for simulating soil body interlayers with different strengths. The slope model can be used for slope deformation monitoring research under the condition of quantitative grouting reinforcement of the weak intercalated layer, and has the advantages of simple structure and high testing efficiency.

Description

technical field [0001] The invention belongs to the technical field of geotechnical tests, in particular to a slope model containing weak interlayers and a method for monitoring forming deformation. Background technique [0002] Model test research is one of the means to investigate slope deformation under certain loads and different interlayer strength characteristics. The production of models is the key to the success of model tests. The interlayer soil is relatively loose, and quantitative grouting can be used to achieve different It is of great scientific and theoretical significance to study the strength characteristics of the weak interlayer of the slope and its influence on the deformation. [0003] Modeling of slopes with weak interlayers is a device used to study the strength characteristics of weak interlayers on slope deformation. Model making is an important part of model testing. However, the current research on weak interlayers mainly relies on field slope tes...
