Description

Technical Field

[0001] The present invention relates to the technical field of coastal engineering, and particularly relates to a design method for a armor block structure. Background Art

[0002] In coastal engineering design, it is generally a typical sloping breakwater structure. The sloping breakwater structure is constructed with armor blocks. Under the action of long-period waves, the stabilities of different armor blocks for constructing the sloping breakwater structure are different. At the same time, there are many factors affecting the stability of the armor blocks, which increases the difficulty of selecting the structure type of the armor blocks. Currently, there is a lack of a design method that can accurately select the armor block structure to enhance the structural stability of the sloping breakwater structure. Summary of the Invention

[0003] In view of this, it is necessary to provide a design method for an armor block structure to achieve the purpose of improving the structural stability of the sloping breakwater structure.

[0004] To solve the above problems, the present invention provides a design method for an armor block structure, including:

[0005] Based on the wave height, wave period, slope gradient, and spectral peak elevation factor of the target sea area, calculate the stability coefficient of the acropode block, the stability coefficient of the double block, and the stability coefficient of the dumped rockfill.

[0006] Determine the first stability coefficient difference between the calculated stability coefficient of the acropode block and the target stability coefficient of the acropode block, determine the second stability coefficient difference between the calculated stability coefficient of the double block and the target stability coefficient of the double block, and determine the third stability coefficient difference between the calculated stability coefficient of the dumped rockfill and the target stability coefficient of the dumped rockfill.

[0007] Based on the first stability coefficient difference, the second stability coefficient difference, and the third stability coefficient difference, determine that the block or rockfill with the highest stability is the required armor block structure.

[0008] In a possible implementation manner, the calculation formula for the stability coefficient of the acropode block is:

[0009]

[0010] Wherein, K D represents the stability coefficient of the acropode block, β D represents a preset calculation coefficient, γ represents the spectral peak elevation factor, H 1 / 3 represents the wave height of the target sea area, TH1 / 3 represents the effective wave period, α represents the slope gradient, g represents the acceleration due to gravity.

[0011] In a possible implementation, the stability coefficients of the tetrapod blocks include: the average stability coefficient of the tetrapod blocks and the envelope stability coefficient of the tetrapod blocks;

[0012] Among them, the β D value corresponding to the average stability coefficient of the tetrapod blocks is 220.9, and the β D value corresponding to the envelope stability coefficient of the tetrapod blocks is 153.9.

[0013] In a possible implementation, the calculation formula for the stability coefficient of the double-block is:

[0014]

[0015] Among them, K D represents the stability coefficient of the double-block, β D represents a preset calculation coefficient, γ represents the spectral peak elevation factor, H 1 / 3 represents the wave height of the waves in the target sea area, T H1 / 3 represents the effective wave period, α represents the slope gradient, g represents the acceleration due to gravity.

[0016] In a possible implementation, the stability coefficients of the double-block include: the average stability coefficient of the double-block and the envelope stability coefficient of the double-block;

[0017] Among them, the β D value corresponding to the average stability coefficient of the double-block is 219.26, and the β D value corresponding to the envelope stability coefficient of the double-block is 165.47.

[0018] In a possible implementation, the stability coefficients of the dumped riprap include: the average stability coefficient and the envelope stability coefficient when the allowable instability rate of the dumped riprap is 1%, and the average stability coefficient and the envelope stability coefficient when the allowable instability rate is 2%.

[0019] In a possible implementation, the calculation formula for the average stability coefficient of the dumped riprap when the allowable instability rate is 1% is as follows:

[0020]

[0021]

[0022]

[0023] Among them, K D-块石1%-平均 represents the average stability coefficient when the allowable instability rate of the dumped rubble is 1%, γ represents the spectral peak elevation factor, H 1 / 3 represents the wave height of the waves in the target sea area, T H1 / 3 represents the effective wave period, α represents the slope gradient, g represents the acceleration due to gravity.

[0024] In a possible implementation, the calculation formula for the envelope stability coefficient when the allowable instability rate of the dumped rubble is 1% is as follows:

[0025]

[0026] Among them, K D-块石1%-包络 is the envelope stability coefficient when the allowable instability rate of the dumped rubble is 1%.

[0027] In a possible implementation, the calculation formula for the average stability coefficient when the allowable instability rate of the dumped rubble is 2% is as follows:

[0028]

[0029] Among them, K D-块石2%-平均 is the average stability coefficient when the allowable instability rate of the dumped rubble is 2%.

[0030] In a possible implementation, the calculation formula for the envelope stability coefficient when the allowable instability rate of the dumped rubble is 2% is as follows:

[0031]

[0032] Among them, K D-块石2%-包络 is the envelope stability coefficient when the allowable instability rate of the dumped rubble is 2%.

[0033] The beneficial effect of adopting the above implementation is that the design method of the armor block structure provided by the present invention

[0034] Based on the wave height, wave period, slope gradient, and spectral peak elevation factor of the target sea area, calculate the stability coefficients of Dolos blocks, double-linked blocks, and dumped riprap. Based on the stability coefficients, determine the block or riprap with the highest stability as the required armor block structure. Under the same wave steepness, as the spectral peak elevation factor increases, that is, the spectral shape becomes narrower, the instability wave height of the armor block becomes smaller, which means the armor block is more likely to become unstable. The instability wave height has an increasing trend as the wave steepness decreases, that is, the greater the wave steepness, which means the shorter the relative period, the greater the instability wave height, and the less likely the armor block is to become unstable. At the same time, the wave period and the breakwater slope also affect the stability of the armor block. The design method of the armor block structure provided by the present invention fully considers the wave height, wave period, slope gradient, and spectral peak elevation factor of the target sea area when designing the armor block structure, and then selects the armor block structure with the strongest stability to achieve the purpose of improving the structural stability of the rubble-mound breakwater structure.

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0039] In the description of the embodiments of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0040] In the embodiments of the present invention, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, device, product, or equipment that includes a series of steps or modules does not necessarily have to be limited to those clearly listed steps or modules, but may include other steps or modules that are not clearly listed or are inherent to these processes, methods, products, or equipment.

[0041] In the embodiments of the present invention, the naming or numbering of steps does not mean that the steps in the method flow must be executed in the time / logical sequence indicated by the naming or numbering. The named or numbered process steps can be changed in the execution order according to the technical purpose to be achieved, as long as the same or similar technical effects can be achieved.

[0042] Referring to "embodiments" herein means that the specific features, structures, or characteristics described in connection with the embodiments may be included in at least one embodiment of the present invention. The phrase may not necessarily refer to the same embodiment at various positions in the specification, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein may be combined with other embodiments.

[0043] As Figure 1 shown, the present invention provides a design method for a revetment block structure, including:

[0044] S101. Calculate the stability coefficient of the tetrapod block, the stability coefficient of the double block, and the stability coefficient of the dumped rock based on the wave height, wave period, slope gradient, and spectral peak elevation factor of the target sea area.

[0045] S102. Determine the first stability coefficient difference between the calculated stability coefficient of the tetrapod block and the target stability coefficient of the tetrapod block, determine the second stability coefficient difference between the calculated stability coefficient of the double block and the target stability coefficient of the double block, and determine the third stability coefficient difference between the calculated stability coefficient of the dumped rock and the target stability coefficient of the dumped rock.

[0046] S103. Determine the block or rock with the highest stability as the required revetment block structure based on the first stability coefficient difference, the second stability coefficient difference, and the third stability coefficient difference.

[0047] It can be understood that among the first stability coefficient difference, the second stability coefficient difference, and the third stability coefficient difference, the block or rock corresponding to the smallest stability coefficient difference is the most stable revetment block structure, that is, the required revetment block structure.

[0048] Under the action of long-period waves, the instability process of the revetment block is as follows:

[0049] During the process of the test waves gradually increasing from smaller waves, when the waves reach a certain value (critical waves), the revetment blocks begin to become unstable and start to fall, and the first unstable blocks are basically within the range of one wave height above and below. Continuing to increase the wave height will cause rapid large-area damage, and even the entire breakwater section will collapse.

[0050] Effect of slope gradient: For armor blocks of the same weight, as the slope gradient of the breakwater becomes steeper, the instability wave height decreases, that is, the blocks become more unstable. However, for dumped rubble, there is an unfavorable Irribarren number that takes into account the combined effects of slope gradient and wave steepness.

[0051] Effect of spectral peak elevation factor: Under the condition of the same wave steepness, as the spectral peak elevation factor increases, that is, the spectral shape becomes narrower, the instability wave height of the armor blocks becomes smaller, that is, the armor blocks are more prone to instability.

[0052] Effect of wave steepness: (1) For Dolos blocks and twin-blocks, as the wave height increases, the instability rate of the armor blocks increases; for armor blocks of the same weight, the instability wave height increases with the increase of wave steepness, that is, the smaller the wave steepness, which means the longer the relative period, the smaller the instability wave height, and the more prone the armor blocks are to instability. (2) For dumped rubble of the same weight, there is an unfavorable Irribarren number. When the Irribarren number is less than this Irribarren number, the instability wave height tends to increase with the increase of wave steepness, that is, the smaller the wave steepness, which means the longer the relative period, the larger the instability wave height, and the less prone the armor rubble is to instability; when the Irribarren number is greater than this Irribarren number, the instability wave height tends to increase with the decrease of wave steepness, that is, the larger the wave steepness, which means the shorter the relative period, the larger the instability wave height, and the less prone the armor blocks are to instability.

[0053] Combined effect of wave period and breakwater slope on the stability of armor blocks: The stability number N3 of the blocks has a good correlation with the Irribarren number ξ, which is a parameter reflecting the wave state on the slope.

[0054] In some embodiments, the calculation formula for the stability coefficient of Dolos blocks is:

[0055]

[0056] Wherein, K D represents the stability coefficient of Dolos blocks, β D represents a preset calculation coefficient, γ represents the spectral peak elevation factor, H 1 / 3 represents the wave height of the waves in the target sea area, T H1 / 3 represents the effective wave period, α represents the slope gradient, g represents the acceleration due to gravity.

[0057] Furthermore, the stability coefficient of Dolos blocks includes: the average stability coefficient of Dolos blocks and the envelope stability coefficient of Dolos blocks;

[0058] Among them, the value corresponding to the average stability coefficient of the acropode is β D 220.9, and the value corresponding to the envelope stability coefficient of the acropode is β D 153.9.

[0059] It can be understood that for the acropode, the target stability coefficient of the acropode is a constant, that is, the stability coefficient is between 15 and 18, while the recommended value in the British code is 10 - 12, but neither considers the influence of the slope of the breakwater and the wave period (wave steepness).

[0060] The stability coefficient is related to the wave height, period (wave steepness), slope of the slope, and spectral peak elevation factor of the wave. To further compare and analyze the difference between the stability coefficient and the recommended values in relevant codes, as an example, the slope is m = 1.5, and the spectral peak elevation factor γ = 3.3. The stability coefficient calculated by the average formula and the stability coefficient calculated by the envelope formula vary with the period are presented, and the recommended values of relevant codes are given for comparison. Among them, the recommended value of the stability coefficient in the Chinese code is 15 - 18, and the recommended value of the stability coefficient in the British code is 10 - 12. The variation law of the stability coefficient with the wave height and period is the same, that is, under the same period condition, the greater the wave height, the greater the stability coefficient; under the same wave height condition, the stability coefficient decreases with the increase of the wave period. Further, it can be seen that the stability coefficient calculated by the envelope formula is smaller than the stability coefficient calculated by the average formula (that is, taking the stability coefficient calculated by the envelope formula is on the safe side). At the same time, the stability coefficient calculated by the average formula is generally larger than the recommended values in the Chinese and British codes, but when the period is small, the stability coefficient calculated by the envelope formula is comparable to the recommended values (especially the recommended value in the Chinese code). It should be noted that neither the Chinese nor the British code recommendations for the stability coefficient consider the influence of the wave period, and at the same time, the values given in the code generally consider a certain safety margin, so it is reasonable that their recommended values are smaller than the stability coefficient corresponding to the critical instability of the block.

[0061] For the acropode armor blocks of the same weight, the instability wave height increases with the increase of the wave steepness, that is, the smaller the wave steepness, which means the longer the relative period, the smaller the instability wave height, and the easier the armor blocks are to be unstable; under the same wave steepness condition, with the increase of the spectral peak elevation factor, that is, the narrower the spectrum type, the smaller the instability wave height of the armor blocks, that is, the easier the armor blocks are to be unstable; for the acropode blocks of the same weight, with the slope of the slope breakwater becoming steeper, the instability wave height decreases, that is, the blocks are more unstable.

[0062] In some embodiments, the calculation formula for the stability coefficient of the double block is:

[0063]

[0064] Among them, K D represents the stability coefficient of the double-block body, β D represents the preset calculation coefficient, γ represents the spectral peak elevation factor, H 1 / 3 represents the wave height of the waves in the target sea area, T H1 / 3 represents the effective wave period, α represents the slope gradient, g represents the acceleration due to gravity.

[0065] Furthermore, the stability coefficient of the double-block body includes: the average stability coefficient of the double-block body and the envelope stability coefficient of the double-block body;

[0066] Among them, the average stability coefficient of the double-block body corresponds to β D The value is 219.26, and the envelope stability coefficient of the double-block body corresponds to β D The value is 165.47.

[0067] It can be understood that in one embodiment, the slope is m = 1.5, the spectral peak elevation factor is 3.3, the stability coefficients calculated by the average formula and the envelope formula of the double-block body change with the period, and the recommended stability coefficients for the tetrapod blocks in domestic and foreign codes are compared. The recommended value of the stability coefficient in the Chinese code is 15 - 18, and the recommended value of the stability coefficient in the British code is 10 - 12.

[0068] Consistent with the results of the aforementioned tetrapod blocks, the variation laws of the stability coefficient of the double-block body with wave height and period are the same, that is, under the same period condition, the greater the wave height, the greater the stability coefficient; under the same wave height condition, the stability coefficient decreases with the increase of the wave period. The stability coefficient calculated by the envelope formula is smaller than that calculated by the average formula (i.e., taking the stability coefficient calculated by the envelope formula is on the safe side). At the same time, the stability coefficient calculated by the average formula is generally larger than the recommended values in the Chinese and British codes, but the stability coefficient calculated by the envelope formula is comparable to the recommended values (especially the recommended value in the Chinese code) when the period is small. Compared with the stability coefficient of the tetrapod blocks, under the same wave height and period conditions, the stability coefficient of the double-block body is larger, which indicates that the stable weight of the double-block body is smaller than that of the tetrapod blocks.

[0069] In some embodiments, the stability coefficient of the dumped rock includes: the average stability coefficient and the envelope stability coefficient when the allowable instability rate of the dumped rock is 1%, and the average stability coefficient and the envelope stability coefficient when the allowable instability rate is 2%.

[0070] In some embodiments, the calculation formula for the average stability coefficient when the allowable instability rate of the dumped rock is 1% is as follows:

[0071]

[0072]

[0073]

[0074] Wherein, K D-块石1%-平均 represents the average stability coefficient when the allowable instability rate of the dumped rock is 1%, γ represents the spectral peak elevation factor, H 1 / 3 represents the wave height of the waves in the target sea area, T H1 / 3 represents the effective wave period, α represents the slope gradient, g represents the acceleration due to gravity.

[0075] In some embodiments, the calculation formula for the envelope stability coefficient when the allowable instability rate of the dumped rock is 1% is as follows:

[0076]

[0077] Wherein, K D-块石1%-包络 is the envelope stability coefficient when the allowable instability rate of the dumped rock is 1%.

[0078] In some embodiments, the calculation formula for the average stability coefficient when the allowable instability rate of the dumped rock is 2% is as follows:

[0079]

[0080] Wherein, K D-块石2%-平均 is the average stability coefficient when the allowable instability rate of the dumped rock is 2%.

[0081] In some embodiments, the calculation formula for the envelope stability coefficient when the allowable instability rate of the dumped rock is 2% is as follows:

[0082]

[0083] Wherein, K D-块石2%-包络 is the envelope stability coefficient when the allowable instability rate of the dumped rock is 2%.

[0084] It is understandable that since the revetment blocks are randomly filled with two layers of dumped rubble stones and the allowable instability rate is 1% - 2%, the analysis was carried out under two conditions where the allowable instability rates are n = 1% and n = 2% respectively.

[0085] First, the results under the condition of an allowable instability rate of n = 1% were analyzed. Different from the test results of the above two types of artificial blocks, there is a most unfavorable wave steepness. Correspondingly, the stability number N of the dumped rubble stones does not change monotonically with the Iribureen number ξ, and there is a most unfavorable Iribureen number of ξ = 4.8. Considering the influence of the spectral peak elevation factor at the same time, the average and envelope of the stability number of the stable weight of the dumped rubble stones when the instability rate n = 1% were obtained.

[0086] When the allowable instability rate is n = 1%, under the condition of the same wave steepness, the calculation result of the Tanbo formula is greater than that of the fitting average formula of the present invention, but it is basically equivalent to the envelope result in the present invention. The calculation result of the Hudson formula is close to the calculation result of the fitting formula (average value) under the condition of H3 / Lo = 0.03 - 0.05, indicating that the calculation result of the fitting formula in the present invention is reasonable. Similarly, when the allowable instability rate is n = 1% and under the condition of the same wave steepness, the calculation result of the Tanbo formula is basically equivalent to the calculation result of the envelope of the fitting formula in the present invention. At the same time, the calculation result of the envelope formula is greater than the above average calculation result, but the calculation result of the Hudson formula is also relatively close to the calculation result of the fitting formula (average result) under the condition of H113Lo = 0.03 - 0.05.

[0087] The comparison result with the calculation result of the Van der Meer formula shows that under the condition of the same wave steepness, the calculation result of the Van der Meer formula is basically consistent with the average value of the fitting formula of the present invention. Further comparing the change results of the rubble stone weight calculated by the fitting formula and the Van der Meer formula with the wave steepness shows that the change of the rubble stone weight calculated by the fitting formula and the Van der Meer formula with the wave steepness is basically the same, and there is a most unfavorable wave steepness. However, the most unfavorable wave steepness becomes smaller as the slope becomes gentler. When the slope is 2.0, the most unfavorable wave steepness of the Van der Meer formula is slightly greater than the result of the present invention. The reason for the existence of the most unfavorable wave steepness is that the instability of the rubble stones is related to both the slope of the slope and the wave steepness at the same time. The state of the wave depends on the Irrebaren number defined above, which reflects the relative magnitude of the slope of the slope and the wave steepness. It should be noted that the Irrebaren number in the Van der Meer formula is related to the slope of the slope, while the critical Irrebaren number of the result of the present invention is 4.8.

[0088] The variation laws of the stability coefficients calculated by the average formula and the envelope formula with wave height and period are consistent. That is, under the condition of the same relatively small period, the larger the wave height, the larger the stability coefficient. However, under different wave height conditions, there is a most unfavorable period. When the period is greater than this unfavorable period, the larger the wave height, the smaller the stability coefficient. At the same time, the stability coefficient calculated by the envelope formula is smaller than that calculated by the average formula. It can be further seen that the stability coefficients calculated by the average formula are all greater than the values recommended by the British code, but the stability coefficient corresponding to the most unfavorable period calculated by the envelope formula is comparable to the value recommended by the British code. The one corresponding to the most unfavorable period calculated by the average formula is slightly smaller than the value recommended by the Chinese code, while the stability coefficient corresponding to the most unfavorable period calculated by the envelope formula is smaller than the value recommended by the Chinese code. The stability coefficients of the armor blocks under the action of longer-period waves are larger than the stability coefficients specified in the codes of various countries.

[0089] For waves with different wave heights, there is a most unfavorable period (i.e., the most unfavorable wave steepness), and this unfavorable period or wave steepness is related to the slope of the slope, that is, it depends on the most unfavorable Irribarren number. Since the critical Irribarren number is 4.8, when the wave steepness is small (when the period is long), when the waves with the same wave height and period act, the weight of the blocks with a slope of m = 2.0 is greater than that of the blocks with m = 1.5, which should be noted when applying. The recommended values of the stability coefficients in the relevant Chinese codes are 15 - 18, and the recommended values of the stability coefficients in the British code are 10 - 12. Compared with the Chinese code, the preliminary recommended values of the British code are on the safe side.
