Abstract
The utility model relates to a triaxial rheology test device for rockfill, which comprises a sample rheological container (1), wherein the sample rheological container (1) is communicated with a water replenishing device (3) through a water inlet pipe (2) with a valve. The triaxial rheology test device for rockfill has the advantages that based on the existing triaxial test device, the water replenishing device is additionally arranged, the actual working conditions of a rockfill dam material are comprehensively considered, the rainfall and upstream water seepage of a rockfill dam in the actual operation and construction are simulated, and the effect of water is taken into account in the deformation of the rockfill, accordingly, the long-term deformation process of the rockfill can be obtained more accurately, the structure is simple, and the maneuverability is strong.
Description
Technical field
The utility model relates to rock mass mechanics test unit technical field, a kind of specifically rockfill triaxial rheology test unit.
Background technology
The main cause that produces the enrockment rheology is due to grain breakage refinement, the slippage filling hole.Existing many scholars have carried out shop experiment research about the rockfill rheology; The Changing Pattern of the enrockment rheology that shop experiment appeared and actual prototype measurement result are similar basically; But at present the enrockment rheology process of shop experiment is accomplished all than comparatively fast; General only needed to tend towards stability in tens hours, and the dam body in the actual engineering generally the time about 3 years could accomplish 80% of total deformation, both have evident difference.Produce the former of difference because the actual operating conditions of rockfill differs bigger in shop experiment sample and the rock-fill dams.General indoor rheological test is not considered the influence of water; In fact the immersion of dam body stockpile particle takes place to soften, and corner angle are broken, arranges thereby the aggravation enrockment internal particle changing of the relative positions or contact point fragmentation cause again; Corresponding can the generation is out of shape; Whole rheology process and rheological results for rockfill all produce certain influence, and existing triaxial test device has been ignored this key factor, and there is some difference to cause test findings and actual result.
The utility model content
The purpose of the utility model provides a kind of rockfill triaxial rheology test unit of considering moisture factor, through simulated rainfall and percolating water, can more objective, accurately reflect rockfill rheology process.
The utility model rockfill triaxial rheology test unit comprises: sample stream variodenser 1, said sample stream variodenser 1 inner chamber is connected with water replanishing device 3 through the water inlet pipe 2 that has valve.
Said water replanishing device 3 comprises: liquid storage container 4, and offer on the liquid storage container 4 and be used for the water delivering orifice that is connected with water inlet pipe 2.
The advantage of the utility model rockfill triaxial rheology test unit is: on existing triaxial test device basic, set up water replanishing device; Combine the actual operating conditions of rock-fill dams material; Rainfall and upper reaches percolating water in simulation rock-fill dams actual motion and the construction have counted the influence of water in the rockfill distortion, can obtain the long-term deformation process of rockfill more accurately; And it is simple in structure, workable.
Description of drawings
Fig. 1 is the structural representation of the utility model rockfill triaxial rheology test unit.
Embodiment
Below in conjunction with accompanying drawing, be example with the ordinary triaxial test device, the utility model is further specified: according to shown in Figure 1; A kind of rockfill triaxial rheology test unit comprises: top cover 5, pressure chamber 6 and base 7, establish sample stream variodenser 1 in the said pressure chamber 6; Said sample stream variodenser 1 is made up of top cover 8, bottom 9 and rubber membrane 10; Bottom 9 is provided with porous disc 11 in the sample stream variodenser 1, and load bar 12 1 ends link to each other with axial loading system, and the other end passes top cover 5 and contacts with top cover 8 then; Drainpipe 13 passes base 7, bottom 9 and porous disc 11 and contacts; Forcing pipe 14 1 ends pass base 7 and are connected with pressure chamber 6, and forcing pipe 14 other ends link to each other with the confined pressure control system, also are provided with valve 15 and tensimeter 16 on the forcing pipe 14; The water inlet pipe 2 of said sample stream variodenser 1 inner chamber through having valve is connected with water replanishing device 3, and mode of communicating is to offer on the top cover 8 to be used for the water inlet that links to each other with water inlet pipe 2, and current are because of action of gravity inflow sample stream variodenser 1 inner chamber; Perhaps mode of communicating is to offer on the bottom 9 to be used for the water inlet that links to each other with water inlet pipe 2, and water pump is with water suction sample stream variodenser 1 inner chamber.
Said water replanishing device 3 comprises: liquid storage container 4, and offer on the liquid storage container 4 and be used for the water delivering orifice that is connected with water inlet pipe 2.
Open the valve of water inlet pipe 2 on the water replanishing device 3, according to the rainfall amount and the definite water yield that adds of dam body unsaturated seepage amount, valve-off; Whether the valve control sample inner inlet through opening or closing on the drainpipe 13 discharges, but the sample inner inlet freely discharge the process that simulated rainfall drains.
More than be connected mode and the principle of work that water replanishing device and ordinary triaxial test device combine; Those skilled in the art should know; Cut triaxial test etc. extraordinary triaxial test such as true triaxial test, Plane Strain Test, hollow turning round; Perhaps dynamic test is cut on triaxial test, the devices such as moving simple shear test, shaketalle test and resonance post triaxial test like moving triaxial test, moving turning round, add water replanishing device according to the technological means of the utility model after, can realize the technique effect that the utility model will obtain equally; Therefore the above is the most preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction, every any simple modification, equivalent variations and modification of above instance being done according to the technical spirit of the utility model all still falls in the protection domain of the utility model.
Claims (2)
