Description
Technical field
Ground indoor direct shear test technical field is the utility model is related to, one kind is more particularly to and is connect for surveying soil with structure
The lower Particle Breakage degree device of contacting surface interaction.
Background technology
The contact interface of different materials is commonly encountered in building, hydraulic engineering.Because contact interface two layers of material mechanics is special
Property difference, larger shear stress is commonly present in interface both sides and generates displacement non-continuous event, stress and is deformed more multiple
It is miscellaneous.Such as the CFRD in hydraulic engineering, the safety and panel stress of dam body are closely related, and panel exists
Stress in plane depends primarily on the shearing stress distribution state of contact surface between panel and bed course.There is the heart in core wall rockfill dam
Wall earth material and filter material, polytype contact interface such as dam shell material and basement rock.These usual contacts site are that dam body is easily sent out again
Make trouble thus weak link, wherein contact surface shear band（Can be along with one stress of material internal in rock-soil material destructive process
The region more concentrated, it is that can be formed through banded regions that the straining concentration zone domain of this high gradient enters critical condition in material
Domain, this phenomenon are referred to as strain localization band or shear band in the mechanics of materials, rock-soil mechanics field.）By shearing to particle
Destruction is the most serious, causes bulky grain to reduce, and little particle increases, and particle size distribution plays an important role to engineering stability, because
This research tool for carrying out shear band Particle Breakage is of great significance.
Due to being limited by instrument and equipment, ground on soil with the Particle Breakage situation of the contact surface shear band of works
Study carefully and be present in surface macroscopic observation more, and the microcosmic quantitative research on the Particle Breakage of contact surface shear band is less.Existing text
Offer and be recited as abundant ancestor pool in 1994 and be directly used in sight with digital photo technologies with miniature " periscope " device and Hu Liming in 2000
Examine structural plane soil and the relative displacement of structural member nearby inquire into soil and the broken of the particle in structure interface shearing test and
Motion change.
Although two kinds of equipment described in document can record the particle motion of contact surface shear band in shearing test, crush
Journey, but Precise collection can not be carried out to particle at contact surface shear band, it is difficult to carry out quantum chemical method.
Utility model content
The purpose of this utility model is solve the problems, such as background technology, there is provided one kind is mutual with structure interface for surveying soil
The lower Particle Breakage degree device of effect.
To achieve the above object, the technical solution adopted in the utility model is that one kind is used to survey soil and structure interface phase
Particle Breakage degree device includes filling structure material under interaction（Concrete, geomembrane etc.）Down cut box, the down cut
The upper shear box device of activity mating connection on the upside of box；The upper shear box device includes the first sleeve, coordinates on the upside of the first sleeve
3rd sleeve is connected, at least one second sleeve is additionally provided between the first sleeve and 3rd sleeve.
The utility model uses following prioritization scheme：
（1）The down cut box and upper shear box device are columnar structured that down cut box diameter is more than upper shear box
Assembly dia.
（2）The first sleeve side is provided with first boss.
（3）Second boss, opposite side are provided with the second sleeve side and is provided with the first groove, the first groove with it is described
There is first boss to correspond to grafting cooperation.
（4）The second groove is provided with the 3rd sleeve side, the grafting corresponding with the second boss of the second groove is matched somebody with somebody
Close.
The utility model has invented one kind for the deficiency of common shear box and existing contact surface shearing test scope
For surveying soil and the lower Particle Breakage degree device of structure interface interaction, there is the equipment feature to be：The equipment not only has directly
Function in scissor test used in common shear box, and Stratified Sampling can be carried out to structure interface shear band particle, it is easy to essence
Really calculate the Particle Breakage situation of the different layerings of shear band.
The utility model has the advantage that：The apparatus structure is simple, easy to process, and easily operation, can sheared
Layering collection is carried out to the particle of contact surface shear band after experiment, is the quantum chemical method provider of contact surface shear band Particle Breakage
Just.
