Under the action of long-period waves, different face blocks used to construct the slope breakwater structure have different corresponding stabilities. At the same time, there are many factors that affect the stability of the face blocks. Among them, the weight of the face blocks plays a vital role in the stability of the face blocks.

[0009] In a possible implementation, the weight of the double-character block includes an average weight of the double-character block. The calculation formula for the average weight of the double-character block is:

[0010] in, W Doublet Block-Average indicates the average weight of the doublet block.

[0011] In a possible implementation, the weight of the double-character block also includes the envelope weight of the double-character block. The envelope weight of the double-character block is calculated as follows:

[0012] in, W Doublet Block - Envelope indicates the envelope weight of the doublet block.

[0013] In a possible implementation, the weight of the dumped blocks includes the average weight of the dumped blocks. When the allowable instability rate of the dumped blocks is 1%, the calculation formula for the average weight of the dumped blocks is:

[0014]

[0015]

[0016] in, W 1%-Block-Average means the average weight of the fill blocks when the allowable instability rate of the fill blocks is 1%.

[0017] In a possible implementation, when the allowable instability rate of the dumped blocks is 2%, the calculation formula for the average weight of the dumped blocks is:

[0018] in, W 2%-Block-Average means the average weight of the fill blocks when the allowable instability rate of the fill blocks is 2%.

At the same time, the wave period and the slope of the breakwater will also affect the stability of the face protection block.

[0031] Reference to an "embodiment" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0032] The present invention provides a method and device for calculating the weight of a face protection block, which are described below respectively.

[0033] like Figure 1 As shown, the present invention provides a method for calculating the weight of a face block, comprising: S101. Calculate the stability coefficient of the twisted block, the stability coefficient of the double-jointed block, and the stability coefficient of the dumped stone block based on the wave height, wave period, slope gradient, and spectrum peak rise factor of the target sea area; S102, determining the required face protection block structure based on the calculated stability coefficient of the twisted king-shaped block, the stability coefficient of the double-shaped block, and the stability coefficient of the dumped fill block; S103. Determine the required weight of the face armor block based on the required face armor block structure, as well as the wave height, wave period, slope gradient and spectrum peak rise factor of the target sea area.

[0034] It can be understood that based on the calculated stability coefficients of the twisted king-shaped blocks, the stability coefficients of the double-shaped blocks and the stability coefficients of the dumped blocks, the required face protection block structure is determined, specifically including: Determine the first stability coefficient difference between the calculated stability coefficient of the twisted Wang-shaped block and the target stability coefficient of the twisted Wang-shaped block, determine the second stability coefficient difference between the calculated stability coefficient of the double-shaped block and the target stability coefficient of the double-shaped block, and determine the third stability coefficient difference between the calculated stability coefficient of the dumped block and the target stability coefficient of the dumped block; The block or stone with the highest stability is determined as the required facing block structure based on the first stability coefficient difference, the second stability coefficient difference and the third stability coefficient difference.

[0035] Among the first stability coefficient difference, the second stability coefficient difference and the third stability coefficient difference, the block or stone corresponding to the smallest stability coefficient difference is the most stable face protection block structure, that is, the required face protection block structure.

[0036] Under the action of long-period waves, the instability process of the armor block is as follows: During the test, the waves gradually increased from smaller waves. When the waves reached a certain value (critical wave), the face blocks began to lose stability and began to fall, and the first unstable blocks were basically located within the range of one and two times the wave height. If the wave height continued to increase, large-scale damage would occur quickly, and even the entire breakwater section would collapse.

[0037] Influence of slope gradient: For the same weight of the facing block, as the slope becomes steeper, the instability wave height decreases, that is, the block becomes more unstable. However, for dumped rock, there is a most unfavorable Irrebaren number that combines the effects of slope gradient and wave steepness.

[0038] Influence of spectrum peak rise factor: Under the same wave steepness, as the spectrum peak rise factor increases, that is, the spectrum becomes narrower, the instability wave height of the protective face block becomes smaller, that is, the protective face block is more likely to become unstable.

[0039] Influence of wave steepness: (1) For twisted blocks and double-jointed blocks, as the wave height increases, the instability rate of the protective blocks increases; for protective blocks of the same weight, the instability wave height increases with the increase of wave steepness, that is, the smaller the wave steepness, that is, the longer the relative period, the smaller the instability wave height, and the easier it is for the protective blocks to become unstable. (2) For dumped blocks of the same weight, there is a most unfavorable Irrebaren number. When the Irrebaren number is less than the Irrebaren number, the instability wave height tends to increase with the increase of wave steepness, that is, the smaller the wave steepness, that is, the longer the period is, the larger the instability wave height, and the less likely the protective blocks are to become unstable; when the Irrebaren number is greater than the Irrebaren number, the instability wave height tends to increase with the decrease of wave steepness, that is, the larger the wave steepness, that is, the shorter the relative period, the larger the instability wave height, and the less likely the protective blocks are to become unstable.

[0040] The combined effect of wave period and breakwater slope on the stability of the face block: the stability number N of the block 3 It has a good correlation with the parameter Irribarren number ξ which reflects the wave state on the slope.

[0041] Under the same wave steepness, as the spectral peak rising factor increases, that is, the spectrum becomes narrower, the smaller the unstable wave height of the face protection block, that is, the easier it is for the face protection block to become unstable, and the unstable wave height tends to increase with the decrease of wave steepness, that is, the greater the wave steepness, that is, the shorter the relative period, the greater the unstable wave height, and the less likely the face protection block is to become unstable. At the same time, the wave period and the slope of the breakwater will also affect the stability of the face protection block. The method provided by the present invention fully considers the wave height, wave period, slope gradient and spectral peak rising factor of the target sea area when designing the face protection block structure, and then selects the face protection block structure with the strongest stability, and determines the corresponding weight of the face protection block structure, so as to achieve the purpose of enhancing the stability of the face protection block.
