Background technology
Past people is when coming down test, need select satisfactory place to carry out hands-on demonstration out of doors according to research object, before this geology soil layer was explored, confirm that its geologic structure and the soil body constitute, be provided with again and cause the rainfall on landslide, analogue means such as groundwater seepage, though such modeling effort can obtain real relatively data, but its research process is too tediously long, workload is big, need to drop into great amount of manpower, material resources, and revision test can not be carried out in same place, therefore people wish can be by carrying out simulation test at the indoor model of setting up the simulating nature soil layer construction, overcoming the defective of outdoor hands-on demonstration, but mostly be at present special circumstances design simulation method voluntarily according to research landslide problem, and Consideration is comparatively single, can not carry out Comprehensive Experiment.
Summary of the invention
At the deficiency that existing laboratory testing rig exists, the object of the present invention is to provide and a kind ofly can bring out the landslide simulation experiment method the water that factors such as the reservoir level fluctuation that causes the landslide, upstream water supply, WATER LEVEL CHANGES are carried out synthetic study.
For achieving the above object, water of the present invention bring out the landslide simulation experiment method carry out as follows:
1. adopt organic glass to make a rectangular box;
2. in the rectangular box bottom one porous disc is set, on porous disc, offers the suitable permeable hole of some sizes, casing is separated into upper and lower two parts with this porous disc;
3. on the sidewall of chamber below the porous disc, offer into, osculum, and operation valve is set respectively;
4. one plate is set above porous disc, on plate, offers the suitable permeable hole of some sizes, square box on the porous disc is separated into left and right two parts by this plate;
5. one deck screen pack is set on the porous disc of bottom in case;
6. in being close to the left side casing of plate, sliding mass is set, reserves suitable distance between the end, slope and the casing left side wall, in the plate right chamber soil sample identical with left chamber can be set;
7. measurement mechanisms such as hydraulic pressure sensor, landslide displacement sensor are set in sliding mass;
8. carry out simulated experiment by output, the height of water level of regulating advancing on the casing, draining valve and plate right chamber, and by observing and measurement mechanism acquisition experimental data.
Further, replace plate and form left and right sides two parts in described casing with an independent case body above described porous disc, independent case body is right chamber.
Further, described porous disc is the steel plate that has permeable hole.
Further, described screen pack is a stainless (steel) wire.
Further, at described bottom half support and hydraulic feed device are set, casing and support are hinged, and casing can be rotated around jointed shaft under the effect of hydraulic feed device.
Further, at described bottom half support is set, on casing top suspension ring is set, suspension ring link to each other with the lifting motor by pulley, and casing and support are hinged, and can rotate around jointed shaft at the effect lower box that lifts by crane motor.
Sloping body in this method can be arranged according to actual conditions, by advancing in the side cavity under the casing, the osculum scalable external height of water level in slope and fluctuation speed, but variation by the permeable hole simulated groundwater water level on the porous disc, chamber by sliding mass one side can be simulated the water supply situation of upstream, can carry out synthetic study at the multiple factor that causes the landslide, also can experimentize to single factors respectively, improve the authenticity and the accuracy of simulation
Description of drawings
