Obtain the in situ rock mass structural fece sample containing weak intercalated layer consistent with live status；2) scene is difficult to obtain and contains weakness
The approximate consistent multiple groups sample of the protolith structure surface properties of interlayer can not obtain structural plane power by the direct shear test of multiple groups sample
Learn index；3) field sampling there are difficulty it is big, costly, the sampling period is long, risk is high the deficiencies of.Therefore, indoor production becomes
Obtain the important method of the sample of rock mass discontinuity containing weak intercalated layer.
Structural plane in engineering containing weak intercalated layer is divided into normal direction load and tangential load, corresponds respectively to different lateral confinements
Constraint condition.Can have 5 kinds of lateral confinement constraint types under normal direction loading environment: 1) the full lateral confinement constraint in four sides limits weak intercalated layer
It squeezes out；2) four sides are entirely free, weak intercalated layer can be allowed freely to squeeze out；3) the full lateral confinement constraint in three sides, side is free, allows weak folder
Layer is squeezed out from side；4) the full lateral confinement constraint in two sides, two sides are free, and weak intercalated layer is allowed to squeeze out from free side；5) the full lateral confinement in side
Limit constraint, three sides are free, and weak intercalated layer is allowed to squeeze out from three side free sides.Under tangential loading environment, since shear direction is wanted
It is subjected to displacement, needs to be free boundary condition, also have 3 kinds in the direction perpendicular with shear direction without constraint in shear direction
Lateral confinement constraint type: 1) the full lateral confinement constraint in two sides limits squeezing out in this two sides for weak intercalated layer；2) two sides are entirely free, Ke Yirang
Weak intercalated layer freely squeezes out；3) the full lateral confinement constraint in side, side is free, and weak intercalated layer is allowed to squeeze out from side free side.In order to
Obtain it is consistent with scene contain weak intercalated layer rock mass discontinuity sample, when sample production indoors, needs and following not only needs
And the test bar that horizontal direction after the compression of sample elder generation normal direction is sheared is able to achieve with the consistent weak intercalated layer constraint condition in scene
Part.And the usually indoor weak intercalated layer rock mass discontinuity sample making step that contains is first to produce rock mass structure surface model sample,
Then the laying of weak intercalated layer is carried out again, not only there is a problem of that interlayer is laid with difficulty, and weak intercalated layer in the production process
The way of restraint frequently with wax coating method, it is difficult to scene constraint condition it is consistent, and normal direction compression process and horizontal direction shearing
Weak intercalated layer is difficult to keep the restrained condition consistent with scene in the process.
