River course.According to experiment needs, bed material is manually laid to certain slope, to simulate the riverbed of different gradient, can be wanted according to experiment
Ask and excavating river course two sides plantation grass seeds, or plug bamboo stick and change riverbank intensity.
(2) water pump is opened, current are extracted out from header tank, enter supply tank by circulation line, supply tank is experimental provision
Steady flow is provided for system;Current pass through flow control valve, suspended body flowmeter again, into forebay;Import overfall is crossed to enter
Enter tank, a part of current are along river course and carry silt through exporting overfall, go out circulation road outflow from river, water is crossed into desilting
Bucket, by filter sand, Graceful stream circulating reflux to header tank;Another part current ooze along under bed material, by seepage flow separating tank, edge
Passage between groove and groove finally goes out circulation road from seepage flow and flows out to header tank, completes water circulation;It is river course that river passage, which goes out stream,
Flow, it is seepage flow flow that seepage channel, which goes out stream, by suspended body flowmeter, river course total flow is read, by graduated cylinder in river passage
The discharge of river and seepage flow flow are measured with seepage channel outlet.
(3) it can simulate different weather by hair-dryer, shower, lighting tube, such as sunny calm weather, sunny have
Wind weather, wet weather have wind weather etc., investigate the situation in different weather situation Imitating river.
(4) image acquisition device is a kind of novel surface flow field image speed measurement (PTV) system based on infrared photography, uses particle
Track the fast method of image measurement and replace the missing particle of the materials such as traditional plastics using primary low-temperature ice particle, on the one hand improve
The thawing of application effects, on the other hand ingenious utilization ice particle of the PTV in complicated light environment, the husky environment of complicated water, environmental protection,
It is convenient, solve missing particle and be detained seashore and the problem of recirculating zone be inconvenient to reclaim, according to testing section length in model river
Stream top is settable one, and two or more image collecting devices, device connects data acquisition and procession by data connecting line
Computer.During experiment, real time image collection is carried out to the missing particle for being sprinkled into river course surface by recognizing, and to the image of collection
Carry out particle identification, matching and the measurement of tracking form and surface flow field.The time interval of shooting be 5~30 minutes, specifically by
The speed of river course metamorphosis is determined.The image that shooting is obtained carries out straightening and Coordinate Conversion in computer, and recognizes
The river course two sides gone out in every piece image, catch the overall process that model stream plane configuration is developed.
Fig. 8 be experimental rig of the present invention plane figure, as illustrated, by river course be divided into S1, S2, S3, S4, S5, S6,
S7, carries out data and takes, and carries out 5 groups of contrast experiments, and contrast test is designated as RUN1, RUN2, RUN3, RUN4, RUN5 respectively,
As a result it is as shown in the table:
The experimental group time of table 1 and primary data
It can be seen that by Fig. 9 and Figure 10, RUN1 seepage dischargies are substantially big compared with RUN2~RUN5, be because initial bed surface is in insatiable hunger
And saturation state, seepage flow gradient is far longer than saturation state, this be also many scholar's research when doing channel change experiment, first note
The reason for water.When bed material reaches saturation state, seepage flow can be approximately decomposed into horizontal seepage flow and longitudinal seepage flow two parts, laterally
The size for depending mainly on the size of inbound traffics of seepage discharge, and longitudinal seepage flow depends on the longitudinal gradient in river course.Under normal circumstances, ooze
Flow can increase with the increase of the discharge of river and hydraulic slope, but influence degree is different.Fig. 9 and Figure 10 is observed to find,
RUN2 is identical with the RUN3 gradients, but flow difference it is larger when, in two groups of experiments seepage discharge excursion difference it is smaller.RUN5 river courses
Seepage discharge is big compared with RUN2, RUN3 and RUN4, although flow is small compared with RUN3 and RUN4, it can be seen that hydraulic slope is for seepage flow
The influence for measuring size is obvious compared with inbound traffics.
Figure 11 be shown experimental observation model stream from it is straight to wriggling, the evolution process of pigtail and point branch of a river.For curved
Qu Heliu, because of the influence of upstream inflow angle, upstream starts bent, so as to influence downstream, upstream downstream river downstream develops delayed
In upstream, river bend curvature has downward transitivity.Figure 11 is the evolutionary process of meandering flow, starting stage, due to typically from upper
Downstream is swum over to, with the continuous progress of differentiation, downstream bay flow condition is gradually ripe, bending speed is increased, and downstream bay is pressed
Developed according to the Evolution Mechanism of itself, while playing restrictive function to upstream.Influence of the inflow angle to the channel change of river bends is short-term
Effect, its change is accelerated in initial time, but on long terms, river can reach the equilibrium-like of itself according to flow and sediment
State.
The silt in experimentation in model river course is shown by measuring silt discharge in desilting cylinder after tail-gate in Figure 12.
Original state silt discharge is smaller, and as current scour and bed material start, silt discharge reaches maximum in channel change about 100min,
Because initial river course is small rectangle river course, and river course discharge capacity is far smaller than given flow, therefore river course is drastically opened up
Width, riverbed is in acutely adjustment evolutionary process.With the formation of basic bend, main stream line occurs, and riverbank and bed surface start surely
It is fixed, the stable sediment transport in river course.
Exemplary description is done to technical scheme above, it should explanation, do not departed from this technology side
In the case of the core of case, any simple deformation, modification or other skilled in the art can not spend creative labor
Dynamic equivalent substitution each falls within the protection domain of this patent.
