Description
Technical field
The utility model belongs to Geotechnical Engineering experimental technique field, is related to balancing gate pit in a kind of triaxial test, more particularly to
A kind of controllable temperature body for earthwork triaxial apparatus, which becomes, measures interior room.
Background technology
With the fast development of modern Geotechnical Engineering construction so that the research that temperature influences on Rock And Soil fundamental property turns into
One important topic.Laboratory test is to study the necessary means of Rock And Soil temperature effect, but existing general earthwork triaxial apparatus
Temperature control test function can not be realized, therefore this just needs to transform existing general earthwork triaxial apparatus perfect, is allowed into
For the earthwork triaxial apparatus of alternating temperature control, i.e. temperature control earthwork triaxial apparatus can be realized.At present, to the temperature of existing general earthwork triaxial apparatus

Promoted between the earthwork triaxial apparatus of different model or structure, and general geotechnical centrifuge model and temperature control geotechnical centrifuge model can be realized
Between free switching temperature regulating device.
General earthwork triaxial apparatus is when measuring volume of sample change, and mainly by two ways, one kind is anti-by measuring
The variable quantity of water volume carrys out the change of inverse sample body in pressure controller, and another kind is the Volume Changes by measuring pressure fluid inside
Amount is carried out inverse sample body and become.The first body becomes measurement mode and is only applicable to saturated sample, and second of measurement mode is then applied to each
The sample of kind different saturation.But second of metering system needs to demarcate balancing gate pit in the case of different temperatures and different confined pressures in advance
And its deformation of connecting line, not only accuracy in measurement is relatively low, and operates very cumbersome.Therefore there is an urgent need for a kind of letter of research and development
Just, it is economical, can accurately be measured under the conditions of temperature variable load sample body change device.
