Description
Technical field
The invention belongs to soil test field, it is related to a kind of inclined clay sample cut mold of depositional plane and its operation side
Method.
Background technique
In Practical Project, stress along different directions load the phenomenon that it is extremely widespread.Studies have shown that stress adds along different directions
When load, native mechanical characteristic is different.
In laboratory experiment, the fundamental test for studying the mechanical characteristic of soil includes: direct shear test, triaxial test, true triaxial examination
It tests and hollow cylinder torsional scissor test etc..For original state and reshaped clay, big principal direction of stress is usually vertical with depositional plane.
When most of test cannot all consider to load along different directions, influence of the stress direction angle to the mechanical characteristic of soil.It may be noted that
Although hollow cylinder torsional shear instrument can consider the influence at a stress direction angle, in practical projects, due to geology
Effect, the often run-off the straight of the depositional plane of the soil body, therefore, depositional plane tilts in one direction and stress is inclined along another direction
The phenomenon that turning is extremely widespread, and existing research technique can not simulate above-mentioned phenomenon.
It has been realized that the importance of this characteristic of soil, and have carried out some research.For remodeling sand examination
For sample, by tilting sand replacement method, the preparation of depositional plane inclination sample may be implemented, and achieve certain achievement.But incline
The method for making sample of oblique clay sample there is no.
Summary of the invention
In view of this, the purpose of the present invention is to provide a kind of inclined clay sample cut mold of depositional plane and its operations
Method to the molding of geotechnical sample and is cut the processing that sample process standardizes by standardized mold, is matched with pressure-like device
Close, can strict control sample depositional plane direction and cutting direction, as far as possible reduction sample making course in manual operation to sample preparation matter
The influence of amount improves the repeatability of sample preparation as much as possible.
In order to achieve the above objectives, the invention provides the following technical scheme:
A kind of inclined clay sample cut mold of depositional plane, the mold including being used to prepare geotechnical sample；The mold
In hollow form and with an opening；The unhindered settling face of geotechnical sample is the first plane, and the second plane is perpendicular to the first plane；Institute

Optionally, before step " being cut to clay in mold in the gap between adjacent molds unit ", disassembly
Part mould unit.
The beneficial effects of the present invention are:
(1) sample preparation is standardized
There is no the inherent anisotropies for considering sample for the prior art, in sample making course, not to the cutting angle of sample
Degree or depositional plane angle are strictly controlled.And due to needing a large amount of manual operation in sample cut, it is prepared
Sample it is larger by artificial affecting.The present invention forming to sample and is cut sample process and carried out at standardization by standardized dies
Reason, cooperation test pressure-like device with multifunctional earth, utmostly shadow of the manual operation to sample quality in reduction sample making course
It rings, improves the repeatability of sample preparation as much as possible.
(2) it is suitable for original state and remoulded clay
The prior art is only capable of manually preparing the inclined remodeling sand of depositional plane, helpless to clay.Typically, original state
Clay and reshaped clay sample are both needed to the process by cutting sample in the preparation, based on the basic principle for cutting sample method sample preparation, the present invention
It can be used for cutting original state and remoulded clay simultaneously.
(3) it can control the depositional plane direction of sample
Existing sample making technology cannot accurately control the depositional plane direction of clay sample.The present invention can be ground by standardization
Tool, the cutting direction of stringent Control Assay.And then it can realize that dead axle is cut using direct shear apparatus, triaxial apparatus and true triaxil tester etc.
Shearing stress path.
