Description
Technical field
The invention belongs to the test apparatus field in engineering machinery, damage multiple dimensioned measurement system in particular to a kind of Mineral rheology, be applicable to synchronous damage-free under high confining pressure aqueous solution and other hydraulic fluid condition and observe the inside and outside rheologic time Evolutions such as rock softening crackle.
Technical background
The strength loss of engineering soft rock under water effect is the place of the basic reason that many Important Project disasters occur.Its key is: under the effect of aqueous solution, the effects such as rock generation physics, chemistry, causes that it is loosely organized, unit separation, crack propagation, to gather together, thus its intensity is significantly reduced, destroy.Namely many side slopes, tunnel, foundation ditch etc. produce the main cause of destruction under rainfall impact for these.Rock And Soil and aqueous phase interaction are study hotspot and the advanced subject of current Geotechnical Engineering circle.
But, the pressure chamber of existing indoor instrument and equipment mostly is totally-enclosed, opaque, cannot in test to the crack growth of sample surfaces, gather together, destruction etc. carries out multiple dimensioned observation, also can only carry out the microscopic observation of surface crack development in the band forms pressure chamber of indivedual software engineering researchers invent, lacks the conjunctive use with internal injury technology; Thus, observation or the mensuration of inside and outside damage can not be carried out, the overall process of reflection rock deformation and failure that also just can not be three-dimensional simultaneously; Still need at present and be conceived to new material and the exploitation and the utilization that damage observation technology, the Simultaneous Determination of inside and outside damage develops new research technique.In addition, traditional electromagnetic sensor is due to the electric conductivity of water, cause it cannot carry out the measurement of physical quantity under water, thus, when water is as confined pressure medium, also just cannot directly working sample itself strain (power) and distortion distribution and situation of change, like this, also just quantitatively cannot answer destruction is the problem how occurring to develop, that is: deformation failure overall process mechanism cannot obtain test figure support.Due to the existence of these key issues, be difficult to the test and the simulation that realize soft rock softening overall process under its Environmental effect condition, thus, seriously constrain and the mechanism of the Important Project disasters such as landslide, landslide is explored and hypothesis in theory checking work.
Therefore, develop a kind of measurement system being applicable to the inside and outside rheologic time Evolutions such as under high confining pressure aqueous solution and other hydraulic fluid condition synchronous damage-free observation rock softening crackle, there is boundless application prospect.
Summary of the invention
The object of the invention is, for the demand that rock in existing triaxial test and aqueous phase interaction are tested, provide a kind of and under high confining pressure aqueous solution and other hydraulic fluid condition, the measurement system of the inside and outside rheologic time Evolutions such as rock softening crackle can be observed by synchronous damage-free.
A kind of Mineral rheology that the present invention relates to damages multiple dimensioned measurement system, is made up of microscope camera system, internal injury detection system, 3-D imaging system and high-performance computer.
1) microscope camera system
