According to on-the-spot investigation, as a result, it has been found that, the forest against wave wash of Nenjiang bank mainly uses willow and willow at present, and mainly may be used
It is divided into two class of bearing tree and treelet.Forest against wave wash is broadly divided into tree crown and trunk part, thus according to physical condition, is simulated in experiment
4 kinds of tree-shaped, prototype size are respectively：
I types-trunk height 2.6m, diameter 0.25m and height of tree crown 3.5m, diameter 2.5m；
II types-trunk height 2.6m, diameter 0.15m and height of tree crown 3.5m, diameter 2.5m；
Type III-trunk height 2.6m, diameter 0.15m and height of tree crown 3.5m, diameter 1.7m；
IV types-trunk height 1.6m, diameter 0.07m and height of tree crown 0.8m, diameter 1.3m.
By simulating the wave absorbing effect of 4 kinds of different tree-shaped, scheme comparison is carried out.Different forest against wave wash density compare scheme：Root
According to on-the-spot investigation, as a result, it has been found that, the forest against wave wash density of Nenjiang bank is about 0.2 plant/m at present2, due to the tree crown part of forest against wave wash
It is significantly greater than trunk, answers the density of suitable control forest against wave wash cannot be excessive under the conditions of practical seashore, it need to there are enough spaces
Ensure the growth of forest against wave wash, and the arrangement of Binding experiment room condition, devises the forest against wave wash under the conditions of three kinds of different densities and set
Meter scheme (0.08 plant/m of prototype condition2, 0.17 plant/m2, 0.27 plant/m2), scheme comparison is carried out, since density ratio ruler is 1:
100, thus the lower three kinds of forest against wave wash density of laboratory condition is respectively 8 plants/m2, 17 plants/m2, 27 plants/m.The flexible of different height is planted
Disappeared wave experiment：Further to consider various forms of forest against wave wash wave absorbing effects, flexibility has been carried out in this physical model experiment
The wave absorbing effect of vegetation is tested.The wave absorbing effect of flexible vegetation, the flexible a diameter of 1cm of vegetation are simulated using vinyon silk
(model 1mm), density are 49 plants/m2(model is 4900 plants/m2), i.e., spacing is 10cm between vegetation, meets practical riverbank edge
Reed woods basic growth characteristics.
In view of the different flexible growth conditions of vegetation and the difference of growth ability, two vegetation are devised in this experiment
The wave experiment that disappears of the flexible vegetation of height 2m, 3m (model 20cm, 30cm).And the experiment has found that the flexible zone of vegetation of 30m
50% or more wave absorbing effect can have been reached, thus in view of the factor of economical rationality, flexible vegetation disappears the experimental simulation of wave
Maximum vegetation bandwidth is 30m.Flexible vegetation density contrast experiment：Under physical condition, the plantation of the flexibility vegetation such as reed woods is close
Degree is in 30-70 plants/m2, it is more easy to survive.Thus this logistics organizations devises 25,49,81 plants/m2Under the conditions of three kinds of different densities
Flexible vegetation disappear unrestrained physical model experiment.
In summary experimental program as a result, providing the forest against wave wash arrangement mode of recommendation, forest against wave wash density, forest against wave wash tree-shaped
Design scheme, recommend the forest against wave wash using flexible+big tree combination, the combined forest against wave wash band of the triangular arranged of 40m,
The depth of water is located in hydrostatic level near tree crown, and the minimum unrestrained coefficient that disappears is 40% or so under the conditions of each section, and more economical rationality.
The unrestrained result 1. different arrangement mode forest against wave wash disappear
According to experimental program, each section has been carried out in different arrangement modes (equilateral triangle, square and quincunx) item
The wave experiment that disappears under part.Design water level and Wave parameters are fifty year return period condition, model scale 1：10, vegetation under laboratory condition
Density is 17 plants/m2, trunk diameter 0.7cm, trunk height 16cm, crown diameter 13cm, height of tree crown 8cm.Three sections
Experimental result such as the following table 1,2 and 3.
Wave absorbing effect under 1 low beach section of table under the conditions of different arrangement modes
Wave absorbing effect under the conditions of 2 medium water level beach section difference arrangement mode of table
Wave absorbing effect under the conditions of 3 high beach section difference arrangement mode of table
From the above results, it can be seen that the unrestrained coefficient that disappears under the conditions of different beaches has apparent difference.Compare different plants
It is arranged the wave absorbing effect of forest against wave wash under mode, it is seen then that equilateral triangle and the forest against wave wash of quincunx arrangement are better than rule
Square arrangement mode.More other two sections of wave absorbing effect under the conditions of high beach section are more preferable, the wave effect that disappears of equilateral triangle
Fruit is better than quincunx and square arrangement, and wave absorbing effect is more notable in the forest against wave wash of preceding 30m.In medium beach condition
Under, forest against wave wash has been substantially at floodage, disappear unrestrained coefficient will relatively high beach section it is poor.And under the conditions of low beach section, prevent
The wave absorbing effect wave absorbing effect of unrestrained woods is poor, the difference very little of different arrangement modes, and the unrestrained coefficient that disappears of 50m forest against wave wash is 10%.
Its reason is analyzed, due to a height of 2.4m of tree, forest against wave wash is in complete floodage under the conditions of low beach section, and the energy of wave is more
It concentrates near hydrostatic level, it is poor so as to cause its wave absorbing effect.
The regular wave of comparison and irregular wave absorbing effect, since regular wave is 1/10 big wave, the unrestrained coefficient that disappears is relatively large, but
The two difference is little.And the wave under physical condition is irregular wave, thus the unrestrained coefficient that disappears of irregular wave is more close practical
Condition.
2. the forest against wave wash wave absorbing effect of different densities
According to experimental program, carried out each section different densities forest against wave wash (8 plants/m2 under laboratory condition, 17 plants/
M2,27 plants/m2) under the conditions of the wave experiment that disappears.Design water level and Wave parameters are fifty year return period condition, model scale 1：10, it adopts
With preferably triangular arranged mode relatively, under laboratory condition, trunk diameter 0.7cm, trunk height 16cm, tree crown is straight
Diameter 13cm, height of tree crown 8cm.Experimental result such as the following table 4,5 and 6, each parameter is the prototype parameter of simulation in following table.
Wave absorbing effect under 4 low beach section difference vegetation density conditions of table
Wave absorbing effect under 5 medium water level beach section difference vegetation density conditions of table
Wave absorbing effect under 6 high beach section difference vegetation density conditions of table
From the above results, it can be seen that the unrestrained coefficient that disappears under the conditions of different beaches has apparent difference.Compare different densities
Forest against wave wash wave absorbing effect, it is seen then that the increase of density has significantly improved to wave absorbing effect, especially disappears wave in such tree-shaped
Larger high beach section is acted on, wave damping effect is in preceding 40m forest against wave wash significant effect, and the unrestrained coefficient that disappears is 40% or more.High density item
Vegetation density is further increased under part, and it is smaller to offset unrestrained index impacts.As it can be seen that 0.17 plant/m2(prototype condition) is relatively inexpensive
Rational vegetation intensity scheme.
3. wave absorbing effect under the influence of different incoming wave wave height
According to experimental program, carried out each section different incoming wave wave height (1.1 times of fifty year return period wave height, 50 years one
Meet wave height, 0.9 times of fifty year return period wave height) under the conditions of disappear wave experiment.Design water level is fifty year return period condition, model scale
1：10, using preferably triangular arranged mode relatively, under laboratory condition, trunk diameter 0.7cm, trunk height
16cm, crown diameter 13cm, height of tree crown 8cm.Model experiment results such as the following table 7,8 and 9.Each parameter is the original of simulation in following table
Shape parameter.
Wave absorbing effect under 7 low beach section difference incoming wave wave conditions of table
Wave absorbing effect under 8 medium water level beach section difference incoming wave wave conditions of table
Wave absorbing effect under 9 high beach section difference incoming wave wave conditions of table
From the above results, it can be seen that wave absorbing effect under different wave conditions difference, but difference is smaller, and irregular wave
The unrestrained index variation that disappears it is more stable.Under the conditions of low beach section, due to disappearing, unrestrained coefficient is smaller, thus the evolution with distance for the unrestrained coefficient that disappears
It cannot function as referring to.The rule of unrestrained coefficient of disappearing under other each working conditions is that wave height is bigger, and wave absorbing effect is better, disconnected on high beach
Under the conditions of face, the unrestrained coefficient that disappears of 40m forest against wave wash can reach 40% or so.It is disconnected that the wave absorbing effect of high beach section will be substantially better than low beach
Face.
4. the forest against wave wash wave absorbing effect of different tree-shaped
According to the above experimental result, the relative altitude of forest against wave wash and the depth of water has significantly the wave absorbing effect of forest against wave wash
It influences.Thus carried out different tree-shaped the wave experiment that disappears (according to autoptical conclusion, have chosen 4 kinds of tree-shaped as trunk with
The combination of tree crown condition, design water level and Wave parameters are fifty year return period condition, model scale 1：10, using relatively preferably etc.
Side rounded projections arranged mode, forest against wave wash density are 17 plants/m2.Model experiment results such as the following table 10,11 and 12.Each parameter is in table
Size under the conditions of prototype.
The wave absorbing effect of the forest against wave wash of 10 low beach section difference tree-shaped of table
The wave absorbing effect of the forest against wave wash of 11 medium water level beach section difference tree-shaped of table
The forest against wave wash wave absorbing effect of 12 high beach section difference tree-shaped of table
From the above results, it can be seen that the wave absorbing effect of different tree-shaped has apparent difference.(bearing tree) trunk of tree-shaped 1 compared with
Slightly, tree crown is more dense, thus the unrestrained ability that disappears under low beach section is notable, and the unrestrained coefficient that disappears of 20m forest against wave wash is i.e. on 40% left side
The unrestrained coefficient that disappears on the right side, 50m forest against wave wash can reach 60% or more.The relatively low beach section of the unrestrained coefficient that disappears of medium water level beach is subtracted
It is small.And under high beach section, since water level is smaller, the wave that disappears, wave absorbing effect of the 20m forest against wave wash to irregular wave are mainly carried out by trunk
The unrestrained coefficient that disappears under the conditions of only 15% or so, 50m forest against wave wash reaches 35%.
Tree-shaped 2 is that trunk width is smaller with respect to the difference of tree-shaped 1, by the unrestrained experimental result that disappears as it can be seen that the thickness of trunk offsets
The influence of unrestrained effect is smaller.The unrestrained coefficient that disappears of tree-shaped 3 is less than tree-shaped 2.And the wave absorbing effect of tree-shaped 4 (treelet) is in low beach section
To be significantly less than tree-shaped 1,2,3 with medium water level beach, but other tree-shaped are then substantially better than in high beach section.As it can be seen that different trees
Type has the wave absorbing effect of different section condition important influence, compares its unrestrained coefficient that disappears it is found that the wave damping effect of tree crown is wanted
It is significantly stronger than trunk, thus in forest against wave wash conceptual design, tree crown need to be considered as and disappeared the method for wave.
5. different height flexibility vegetation wave absorbing effect
According to experimental program, carried out each section flexibility vegetation wave absorbing effect experiment (flexible material height be 0.3m and
0.2m).Design water level and Wave parameters are fifty year return period condition, model scale 1：10, under laboratory condition.Model experiment results
Such as the following table 13,14 and 15.Each parameter is the size under the conditions of prototype in table.
13 low beach section flexibility vegetation wave absorbing effect of table
14 medium water level beach section flexibility vegetation wave absorbing effect of table
15 high beach section flexibility vegetation wave absorbing effect of table
From the above results, it can be seen that the wave absorbing effect of flexible vegetation has significant difference in different section.Low beach section
Wave absorbing effect is poor, the unrestrained coefficient about 15% that disappears of 30m flexibility vegetation, and the wave damping effect of high beach section is apparent, 20m flexibility vegetation
Reach 50% or more wave absorbing effect.The flexible vegetation wave absorbing effect of 0.3m high is better than the zone of vegetation of 0.2m.To find out its cause,
It is since the height of flexible vegetation is relatively low, thus the unrestrained ability that disappears under the conditions of high beach section is preferable.And under the conditions of low beach, it plants
Abundant floodage is in by band, thus wave absorbing effect is poor.
6. different densities flexibility vegetation wave absorbing effect
According to experimental program, the unrestrained contrast experiment that disappears of the flexible vegetation of each section different densities has been carried out, has been based on laboratory
Condition has selected 2500,4900,8100 plants/different tri- kinds of m2 vegetation density, carries out the wave experiment that disappears.Design water level and wave are wanted
Element is fifty year return period condition, model scale 1：10, under laboratory condition.Model experiment results such as the following table 16,17 and 18.In table
Each parameter is the size under the conditions of prototype.
16 low beach section flexibility vegetation wave absorbing effect of table
17 medium water level beach section flexibility vegetation wave absorbing effect of table
18 high beach section flexibility vegetation wave absorbing effect of table
From the above results, it can be seen that flexible vegetation is more notable in the wave absorbing effect of high beach section, this is because vegetation is in
Non-submersion state, and flexible differentiation of the vegetation without tree crown and trunk has reached the wave that disappears well due to its relatively intensive distribution
Effect.The density of flexible vegetation is bigger, and the unrestrained coefficient that disappears is better.According to its unrestrained coefficient that disappears as a result, and considering economical rationality
Factor, 4900 plants/m2Flexible vegetation can reach good effect.
7. combined forest against wave wash wave absorbing effect (suggested design)
According to above experimental result, it is contemplated that the difference of different tree-shaped wave absorbing effect under the conditions of different section, in conjunction with
Factor analysis and wave eliminating feature give the suggested design of 4 kinds of combined type forest against wave wash bands.Combination 1：10m flexibility vegetation+30m is big
Tree；Combination 2:The big trees of 10m little trees+30m；Combination 3:20m flexibilities vegetation and the big tree combinations of 20m；Combination 4:20m little trees and 20m are big
Tree.The physical model experiment under the conditions of above 4 kinds of assembled schemes has been carried out, flexible vegetation height is 0.3m under laboratory condition,
Little tree is tree-shaped 4, and big tree is tree-shaped 3, and using triangular arranged mode, forest against wave wash density is 17 plants/m2.Each parameter in table
For the size under the conditions of prototype.
19 low beach section wave absorbing effect of table
20 medium water level beach section wave absorbing effect of table
21 high beach section wave absorbing effect of table
By testing fruit as it can be seen that the wave absorbing effect of each section of assembled scheme is integrally preferable.This is because combined type forest against wave wash side
Case is effectively utilized flexible vegetation/little tree and disappears unrestrained ability and big tree under the conditions of low beach section under the conditions of high beach section
The unrestrained ability that disappears, obtained the effect that the two is taken into account, compared to using single tree-shaped forest against wave wash, can ensure in different section
Under the conditions of wave absorbing effect.Wherein, 20m flexibilities vegetation (49 plants/m of prototype density2) the big tree (0.17 plant/m of prototype density of+20m2)
Combination forest against wave wash best results, the unrestrained coefficient that disappears under the conditions of low beach section is more than 35%, and medium water level beach is more than 40%, high
Beach section is more than 50%.In addition, the combined forest against wave wash planting cost is relatively small, more economical rationality.
Based on autoptical as a result, and with reference to conditions such as the planting densities of practical forest against wave wash and flexible vegetation, rationally setting
Counted forest against wave wash disappear wave physical model experiment scheme, according to physical model experiment as a result, obtaining to draw a conclusion：
(1) related between forest against wave wash and the depth of water since the depth of water of forest against wave wash band is widely different under the conditions of different beaches
Relationship, which offsets unrestrained coefficient, important influence, and the tree crown of forest against wave wash is main energy dissipating part.When forest against wave wash designs, should use up
Amount ensures the tree crown part of forest against wave wash near hydrostatic level so that forest against wave wash can play the role of effective wave resistance.It is i.e. disconnected on low beach
Higher larger forest against wave wash is arranged in face, and short tree-shaped should be arranged in high beach section.
(2) under the conditions of rational forest against wave wash tree-shaped, the unrestrained coefficient that disappears of the forest against wave wash shelter strip breadth of 30-40m 30% or more,
The unrestrained coefficient increase that disappears of the wave resistance shelter strip breadth of bigger is not notable.In view of the factor of economical rationality, the forest against wave wash bandwidth of 40m
It spends relatively reasonable.
(3) forest against wave wash of the different arrangement arrangement modes wave experiment that disappears obtains, the forest against wave wash of the arrangement mode of equilateral triangle
Wave absorbing effect is relatively excellent, and can meet the distance between rows and hills of bigger, is more suitable for the conditions such as the illumination, growth, health of forest against wave wash, pushes away
It recommends and uses triangular arranged mode.
(4) forest against wave wash of the different vegetation density wave experiment that disappears show that the increase of vegetation density can improve the unrestrained coefficient that disappears, but
When forest against wave wash density>0.17 plant/m2When, it can not significantly improve the unrestrained coefficient that disappears.Thus suggest that forest against wave wash density uses 0.17
Strain/m2Left and right, can adequately ensure distance between rows and hills, the more conducively growth in forest belt.
(5) under the conditions of the element of wave of different wave height, the wave absorbing effect of forest against wave wash difference.Wave height is bigger, and disappear wave effect
Fruit is better.
(6) the wave experiment that disappears of flexible vegetation shows that density is 49 plants/m2, the flexible vegetation of a diameter of 1cm has well
Wave absorbing effect.The reed woods height of experimental simulation is 2m and 3m (growing height of reed is usually between 2-3m), disconnected on high beach
There is good wave damping effect in face, but can not be suitable for the larger low beach section of the depth of water.
(7) recommend that flexible+big forest against wave wash for setting combination, the combined forest against wave wash band of 40m is used to can be suitably used for different break
Noodles part, the minimum unrestrained coefficient that disappears is 40% or so under the conditions of each section, and more economical rationality.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations
Also it should be regarded as protection scope of the present invention.
