Fluctuation in stage simulation mechanism comprises inlet opening 17 and osculum 18 that front panel 15 is offered, and inlet opening 17 is connected external intake pump and unwatering pump respectively with osculum 18, tests the fluctuation in stage in framework 1, mimic water-depth fluctuation and souring for realizing.
The roughly process that application the present invention carries out testing is:
One, Landslide Model design and test unit assembled
1, for Research Requirements, according to the principle of similitude, the landslide scale model after generalization is drafted;
2, according to model width, splicing backplate 12, and with similarity model test result for standard, the analog material of preparation sliding bed, slide strips, gliding mass and control structure thing (such as friction pile etc.) respectively.Accurately make landslide physical according to the landslide scale model spatial shape drafted and bury the inner and surperficial monitoring equipment in landslide underground;
3, according to landslide physical width splicing sliding panel 23 and plate 24, composition meets the front panel 15 of width requirement; Promote front panel 15 until the ahead boundaries of close landslide physical; Adopt the fixed front panels 15 such as jig, and arrange that sealing adhesive tape does airtight waterproof process in front panel 15 and backplate 12, chassis base 10 contact position; At landslide physical rear portion, erection loads steel plate 6, loads steel plate 6 parallel with loading surface;
Two, test loads
4, open the control system of hydraulic jack 4, hydraulic jack 4 length continuous elongation, meanwhile test the elevation angle of framework 1 also at consecutive variations; Voltage stabilizing control can be carried out to hydraulic jack 4 when the elevation angle reaches specified angle, guarantee that its elongation remains unchanged, and then guarantee that the elevation angle of testing framework 1 remains unchanged; Elevation angle size is by tiltmeter real-time measurement, display record;
5, the thrust size applied needed for the landslide physical rear portion gone out according to theory calculate, applies constant or fluctuating load by controlling electro-hydraulic loading machine 7 at rear portion, landslide;
6, open intake pump, to the intracontour waterflooding of test framework 1, mimic water-depth rises; Close intake pump, externally drained to test framework 1, mimic water-depth declines; The discharge water yield and the working time of drainage pump is controlled according to simulated condition condition;
Three, data acquisition
7, by related equipment acquisition test data, such as, soil pressure, gliding mass inner absolute displacement and friction pile pile strain etc. is gathered;

Five, off-test
9, the water in test framework 1 is extracted by unwatering pump;
10, close electro-hydraulic loading machine 7, reclaim and load steel plate 6;
11, slow releasing hydraulic jack 4;
12, extract front panel 15 out, and be disassembled into sliding panel 23 and plate 24;
13, backplate 12 is dismantled, the landslide physical after then adopting artificial or mechanical system to remove destruction;
14, cleaning framework base plate 10, backplate 12, sliding panel 23, plate 24, reclaims and waits for that next time uses.
In addition, owing to chassis base 10 being provided with multiple base plate chute 11, therefore also can according to test needs, chassis base 10 inserts two or more backplate 12, and wherein as hereinbefore, the backplate 12 of inner side can not offer backplate chute 13 to two backplates 12 of outer end.After splicing sliding panel 23, plate 24, namely in test framework 1, form multiple separate space.During test, in each separate space, preparation meets the landslide physical of different tests requirement respectively, carries out the parallel experiment of being correlated with, and such as: the sliding mass of same physical dimension, changes the physical and mechanical parameter of material; The landslide physical of same physico-mechanical properties, adopts different geometric shapes; Under simulating different fluctuation in stage condition, the deformation on landslide of the same race; Whether friction skidding device is arranged, or model test when arranging the friction skidding device of multi-form, size; Arrange different landslide physical width, research boundary effect is on the impact etc. of landslide physical.The object that single test completes the parallel experiment of many groups can be realized, add the comparative of test group, eliminate plenty of time and workload simultaneously.
Core of the present invention is the test framework 1 that front panel 15, backplate 12 and chassis base 10 splice and combine, can adjust according to landslide physical size, thus be applicable to the requirement of multiple landslide physical, to set up the three-dimensional space model of meeting geometric simulated condition compared with truly coming down, and achieve the recycling of test framework 1.So its protection domain is not limited to above-described embodiment.Obviously, those skilled in the art can carry out various change and distortion to the present invention and not depart from the scope of the present invention and spirit, such as: the structure that backplate 12 spacing regulative mode adopts base plate chute 11 and backplate return pulley 14 to coordinate is convenient to install and carry out airtight waterproof process, but be not limited to this example structure, adopt other conventional fixed form to be also feasible; Similarly, the connecting method of front panel 15 is also not limited to the form of the grafting mutually of sliding panel 23 and plate 24 in embodiment, if front panel 15 width can be adjusted and with two backplates 12 inside fixing; Bottom lifting mechanism, rear load mechanism and fluctuation in stage simulation mechanism also can utilize existing mechanism to replace.If these are changed and distortion belongs in the scope of the claims in the present invention and equivalent technologies thereof, then the present invention is also intended to comprise these changes and distortion.
