Description
Technical field
A kind of method that the present invention relates to indoor making structural plane model, fills containing organic especially for indoor preparation
The method filling out structural plane model.
Background technology
Structural plane is that rock mass is formed and during the long history of geologic process, the ground being formed in rock mass and constantly growing
Matter interface, the existence of joint plane, is the principal element causing rock mass mechanical characteristic anisotropic, is to affect the dam foundation, side slope
Key condition Deng rock mass engineering stability.The design engineering structure such as the dam foundation, side slope, or when assessing its buckling safety factor, for obtaining
Taking joint plane intensive parameter, the shearing test carried out for rock mass internal structure face is requisite.
According to the difference of structural plane filling state in rock mass, can be divided into without filling structural plane (also known as hard structural plane) and
The big class of filling structural plane two.More currently for the Test And Research Work carried out without filling structural plane, including based on model
The method without filling structural plane and technology is prepared, such as: the zigzag of application cement mortar material making, ripple in usable material chamber
Shape, step-like or column rule fluctuating solid structure surface model；According to 3 d scan data, based on 3D printing technique at rock
Or concrete material obtains without filling structural plane.But, geological researching data shows, in rock mass, most structural plane belongs to
Filling structural plane, therefore, in order to disclose jointed rock mass Shear Failure Features more comprehensively, is required for filling structural plane and carries out
The most deep, experimental test work widely.
In the historical floods that rock mass is formed, ooze under tectonic movement or surface water and all can will be distributed over the organic of earth's surface
Thing is brought into inside rock mass structure, and after mixing with landwaste, association is in rock mass discontinuity, As time goes on, in the ginseng of microorganism
Under with, Organic substance will go bad corruption, thus the mechanics parameter in rock mass original structure face is produced impact.Therefore, study organic
Confrontation filling structural plane shears rule and the mechanism of mechanical characteristic impact, has for analyzing the engineering stability such as dam body, side slope
Important learning value and engineering significance.But, it is limited to uncertainty and the difficulty gathered containing organic primary filling structural plane
Degree, collection in worksite for shearing test containing organic filling structural plane infeasible.
Summary of the invention
Carry out the deficiency of shearing test test to overcome collection in worksite to contain organic filling structural plane, the invention provides
A kind of indoor preparation method containing organic filling structural plane model.
For achieving the above object, solution of the present invention is:
A kind of indoor preparation, containing the method for organic filling structural plane model, chooses cohesive soil, Organic substance, three kinds of materials of cementing agent
Material, by certain volume ratio mixing, prepares filling structural plane mixing material, and wherein cohesive soil accounts for 80%-90%, and Organic substance accounts for 6%-
14%, cementing agent accounts for 2%-8%.Concrete preparation process is: first mixed with Organic substance by cohesive soil, stir, then that cementing agent is uniform
Mix in cohesive soil and organic compound, continue to be stirred until homogeneous.By cohesive soil, cementing agent and organic mixing material
It is laid on the reserved face of lower concrete shearing block 1 making structural plane 3, then upper concrete shearing block 2 is placed in structural plane 3
On, after dense extrusion, it is wound around immersion cotton-padded covering 4 maintenance to cementing agent reaction completely in structural plane 3 surrounding.
Described cementing agent is the hydraulicity or air-setting material.
Described Organic substance is fresh free of contamination Organic substance, and described Organic substance processes through corruption.
Corruption is processed as: in confined conditions, is positioned under 30 DEG C of isoperibols by fresh free of contamination Organic substance and carries out
Corruption processes.
Described lower concrete shearing block and upper concrete shearing are the prefabricated component of reserved step-like mixing material-paving plane.
Owing to have employed such scheme, the invention have the advantages that: 1, preparation is containing organic filling structural plane model
Material therefor easily obtains, and cheap；2, indoor preparation is simple containing organic filling structural plane model method, curing condition
Easily realize；3, three kinds of materials selected by preparation method form similar to the medium containing primary filling structural plane, prepare model
Representative strong.
Accompanying drawing explanation
Fig. 1 is the side view containing organic filling structural plane model,
Fig. 2 is the A-A profile of Fig. 1.
Detailed description of the invention
For clearly and completely describing the indoor preparation method containing organic filling structural plane model, real in conjunction with the present invention
Execute the accompanying drawing of example, the detailed description of the invention of the embodiment of the present invention is done further description, it is clear that described embodiment is only
It is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, the common skill in this area
The every other embodiment that art personnel are obtained under not making creative work premise, broadly falls into the model of present invention protection
Enclose.
1. descend precast concrete cutout 1 and upper precast concrete cutout 2: inside dimension be 200mm × 150mm ×
In the mould of 100mm, prepare according to the proportioning of C40 concrete, and concrete curing box Plays maintenance 28 days, standby.
The most organic corruption processes: under airtight condition, fresh free of contamination Organic substance is positioned over 30 DEG C of isoperibols
Under carry out corruption process, after its putrid and deteriorated one-tenth pasty state use.
