Description
Technical field
This utility model relates to a kind of simulation experiment system about mud-rock flow, is specifically related to a kind of simulation experiment system integrating mud-rock flow startup, migrating and pile up.
Background technology
Data shows according to statistics, and China's debris flow region area has reached 4,300,000 km2, mud-rock flow because its forming process is complicated, outburst suddenly, flow velocity fast, matter content is big, break with tremendous force, last of short duration, destructive power strong and becomes the big disaster that mountain area economy is built.Occur mud-rock flow usually can destroy by rush of water the means of transportation such as road and rail even villages and small towns etc., bring about great losses.But mud-rock flow is frequently experienced in remote mountain areas, its forming process and fluidic structures are more complicated, break out suddenly, cause disaster rapidly, it is difficult to observation.One of the important means of current Debris flow initiation study mechanism and core content are by starting test.Existing a lot of scholars simulate the formation of mud-rock flow by physical simulation experiment, occur, migrate and the process such as accumulation, and achieve inspirer result, and formation and movement mechanism for mud-rock flow propose good opinion, have promoted the progress of mud-rock flow.
The most just from the point of view of the simulation experiment of China's mud-rock flow, two types can be divided into: current scour causes experiment and the experiment of rainfall initiation mud-rock flow of mud-rock flow.For the first type, Most scholars is to use indoor Physical Experiment to study, and uses straight inclined small-sized mud-rock flow channel mould to intend riverbed, and supply tank discharges water the runoff that simulated rainfall produces.The test that such as Wang Zhao print and Zhang Xinyu [being published in " silt research " 1989 the 2nd interim " model investigation of reservoir cohesive deposits sluice vibration "] carry out, the chute be paved with cobble discharges variable concentrations, the mud of different flow or clear water, observation cobble motion under mud stream effect, the formation condition of research mud-rock flow and the characteristics of motion.Zhang Liping and Tang Keli [being published in " mountain research " 1999 the 1st interim " mud-rock flow seedbed loose media starts rainfall simulation and the scouring experiment that discharges water "] Yi Shenfu-Dongsheng mine contributing factor analysis and Jiangjia ravine's nature mud-rock flow are object of study, use rain making and discharge water and wash away analogue experiment method, analyzing dissimilar, mud-rock flow seedbed, different regions loose media starting conditions and mud-rock flow process.For the second type, the numerous experts and scholars of China have carried out a large amount of rain making induction Debris flow initiation test, include indoor Debris flow initiation simulation test and outdoor Debris flow initiation prototype test, but due to outdoor experiment underaction, so many scholars are based on indoor physical simulation test in recent years.Such as, Gao Bing etc. [being published in " Chinese Journal of Rock Mechanics and Engineering " 2011 the 12nd interim " in mud-rock flow start-up course, the grand thin sight of soil-water interaction mechanism is analyzed "] utilize self-control small scale model groove, rainfall simulator in conjunction with controlled rainfall intensity, carrying out the indoor model test of rain making induction mud-rock flow, the different rainfall intensity of research starts the impact of downslide process to grittiness mud-rock flow emphatically.Proposing fine grained in terms of fine grained motion under rainwater effect and loss by test is to cause piling up inside soil body mechanical change and being converted into the principal element of mud-rock flow from of short duration stream earthy state.Hu Mingjian etc. [being published in " Chinese Journal of Rock Mechanics and Engineering " 2003 the 5th interim " Jiangjia Gully Basin heavy rain landslide symbiosis experimental study "] are tested by the test of large-sized artificial rainfall landslide and bench model, experimental phenomena is observed and water content monitoring, study the erosion caused by sloping surfaces, the slump phenomenon occurred under Rainfall Condition and thus cause landslide, the landslide soil body changes into the overall process of mud-rock flow, discloses the heavy rain under Jiangjia Gully Basin special environment, landslide, mud-rock flow symbiosis.
Address existing debris flows simulation experimental provision on but and there are some problems: the two class mud-rock flows that (1) causes for rainfall and current scour, existing mud-rock flow experimental system can only be for one type, it is impossible to the two is combined and studies.(2) the most of raininess of current rain making is the mode of persistence, uniformity, it is impossible to simulate real rainfall.(3) for the factor starting with mud-rock flow, migrating and a series of processes such as accumulation are relevant, such as material composition, grain composition, water status, water condition, thing source slot, circulation groove and the accumulation gradient of plate, roughness etc., rainfall, raininess, rain types, rainfall etc., existing experimental system also can only be for some factors.(4) current experimental system can not fully effective be monitored for key parameters such as the pore water pressure in mud-rock flow experimentation and soil moisture content, matric suction, flow velocity and the impulsive forces of mud flow.(5) existing debris flows simulation device can not carry out mud-rock flow startup, migrates and pile up Whole Process Simulation.(6) existing experimental provision is inconvenient for the full simulation process operation controlling mud-rock flow, and systemization is inadequate.
