Description
Technical field
A kind of the present invention relates to During Geotechnical Tests technical field, more particularly to the rock mechanics examination being placed on turntable of temp. controllable
Test machine.
Background technology
Rock-soil testing machine is a kind of basic science test apparatuses for studying the stress strain curve of ground, by axle pressure system
System, confined pressure system and temperature control system composition, operation principle are to press system to apply axial sample power to sample by axle, pass through
Pressure chamber applies confined pressure to sample, while making to be in respectively not in the middle part of the upper and lower end face of sample, sample by temperature control system
Under same temperature environment, so as to simulate sample multiple actual conditions at different temperatures.Traditional rock test rig is most of
Can only measure the stress strain curve of rock sample, and crackle of the rock in rupture process is produced and evolution
Cannot but be monitored and obtain image.
Rock test technology in recent years has significant progress, and the experimental condition for therefore being proposed is also more and more, rock
Deformation of the stone sample under multi- scenarios method is present study hotspot.Generally include pressure field, temperature field and electromagnetic field etc.
Deng.
With constantly improve and the development of computer technology, CT (Computed Tomography, electronic computer tomography
Scanning) technology of identification is applied to During Geotechnical Tests, and this provides technical basis for observation rock sample rupture process.In order to
Enter Mobile state observation in process of the test to the deformation of each longitudinal cross-section of ground sample, it is necessary in test so that rock
Stone sample has relative rotation with CT scanner.And in order to solve test temperature field stimulation, just must increase in testing machine a set of
Heating and temperature-controlling system.
Lanzhou Inst. of Glaciology and Cryopedology, Chinese Academy of Sciences once carried out rock-soil triaxial tests using CT measuring technologies.They adopt
It is that strain-type triaxial cell is placed directly in CT machines to be scanned, this CT scan method is suitable only for pressure chamber axle
To the relatively low occasion of pressure and ambient pressure, to large-scale rock-soil testing machine and do not apply to, and the testing machine does not simulate temperature
Degree condition.
The 20MN SERVO CONTROL High Temperature High Pressure rock mass three-axis testers that is developed by units such as China Mining University, with confined pressure
The characteristics of big with axle pressure, the size of sample also reachesThe highest thermal-stable temperature of sample reaches
600 DEG C, belong to a kind of testing machine with multi- scenarios method.The testing machine because can not be scanned using CT equipment,
The deformation characteristic of sample can only be obtained, it is impossible to which underbead crack when obtaining specimen broke is produced and evolution.
Patent of invention CN 200620096213.X discloses a kind of Omnibearing scanning rock-soil CT three-shaft instrument, and it is a kind of complete
The triaxial apparatus of nonmetallic making, can not only carry out the scanning of horizontal section, and can carry out the scanning of longitudinal direction (axial direction) section.But
Also axle pressure and confined pressure less occasion are only applicable to, inapplicable to large-scale rock-soil testing machine.The axle pressure of large-scale rock-soil testing machine, enclose
Pressure is larger, must make test specimen tube using metal, so must accordingly using high energy CT machines.Due to large-scale rock-soil testing machine volume
Larger, it is impossible to be directly placed in high energy CT machines and scan, so the test specimen tube part of testing machine must be designed as rotatable part.
Patent of invention 201610248127.4 discloses a kind of rotatable rock mechanics experiment machine, and which can be to big rock sample
Carry out the multi-faceted unobstructed scanning of the horizontal sections of CT and longitudinal section.But the temperature conditionss list that the testing machine can be tested
One, it is only capable of carrying out the rock test under room temperature, the temperature environment of the rock of actually distinct depth of stratum residing for which is to differ
, it is therefore necessary to increasing the firing equipment of a set of temperature-adjustable in testing machine, increase the scope of application of testing machine.
