Description
Technical field
The present invention relates to the technical fields of direct shear test structural plane model production mold, especially containing the knot of weak intercalated layer
Structure surface model makes mold.
Background technique
Structural plane has the influence of controlling, the especially weak structure containing weak intercalated layer to rock stability in engineering
Face.Weak structural face is that have certain thickness weak band in rock mass, have with the rock mass of adjacent two sides compared with high compression, it is low by force
The features such as degree, usually control the deformation and stability of rock mass.In actual engineering project, often caused by weak intercalated layer
Presence lead to Frequent Accidents, cause serious life and property loss, therefore, pass through direct shear test obtain knot containing weak intercalated layer
Research is just particularly important in terms of the mechanical characteristic of structure face.
Obtaining the rock mass discontinuity sample containing weak intercalated layer usually has two kinds of means of field condition sampling and indoor production.It is wild
Outer scene exists following insufficient when obtaining the protolith structural fece sample containing weak intercalated layer: 1) weak intercalated layer easily disturbs, it is difficult to obtain
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.
It is consistent with scene containing weak intercalated layer rock mass discontinuity sample in order to obtain, it is needed when sample makes indoors
There are following 3 aspects to keep the reliability of sample testing: 1) weak interbed identical with field condition；2) with live phase
Consistent weak intercalated layer constraint condition；3) sample can be achieved and first compresses the experimental condition sheared afterwards.It is usually indoor to contain weak folder
Layer rock mass discontinuity sample making step is first to produce rock mass structure surface model sample, then carries out the paving of weak intercalated layer again
If it is difficult not only to there is a problem of that interlayer is laid in the production process, and the way of restraint of weak intercalated layer is frequently with wax coating method,
It is difficult to stress shape consistent with the constrained procedure at scene, and being difficult to keep consistent with scene in compression process and shear history
State.
