[0045] The terms "comprising" and "having" and any variations thereof herein are intended to cover a non-exclusive inclusion, for example a process, method, article, or apparatus that comprises a list of steps or components as alternatives, not by way of limitation, to those stated by enumeration of the steps or components.

The named or numbered flow steps can change the execution order according to the technical purpose to be achieved, as long as the same or similar technical effects can be achieved.

[0047] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase that the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of other embodiments. It is explicitly contemplated that embodiments described herein can be combined with other embodiments.

[0048] The present application provides a weight calculation method and device for a facing block, which are described below respectively.

[0049] As shown in Figure 1 The present application provides a weight calculation method for a facing block, which comprises:

[0050] S101, based on the wave height, wave period, slope gradient and spectral peak elevation factor of the target sea area, the stability coefficients of the twist king block, the double block and the fill block are calculated;

[0051] S102, based on the calculated stability coefficients of the twist king block, the double block and the fill block, the required facing block structure is determined;

[0052] S103, based on the required facing block structure and the wave height, wave period, slope gradient and spectral peak elevation factor of the target sea area, the weight of the required facing block is determined.

[0053] It can be understood that, based on the calculated stability coefficients of the twist king block, the double block and the fill block, the required facing block structure is determined, specifically comprising:

[0054] Determine a 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 a 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 a third stability coefficient difference between the calculated stability coefficient of the dumped fill block and the target stability coefficient of the dumped fill block;

[0055] 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.

[0056] 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.

[0057] Under the action of long-period waves, the instability process of the armor block is as follows:

[0058] During the test, the waves gradually increased from smaller to larger. When the wave reached a certain value (critical wave), the armor blocks began to lose stability and began to fall. The blocks that failed first were generally located within the range of one and two times the wave height. If the wave height continued to increase, it would quickly cause large-scale damage, and even the entire breakwater section would collapse.

[0059] Influence of slope gradient: For a facing block of the same weight, as the slope steepens, the instability wave height decreases, meaning the block becomes less stable. However, for dump fill blocks, there is an optimal Irrebaren number that combines the effects of slope gradient and wave steepness.

[0060] Influence of spectrum peak raising factor: Under the same wave steepness, as the spectrum peak raising factor increases, that is, the spectrum becomes narrower, the instability wave height of the armor block becomes smaller, that is, the armor block is more likely to become unstable.

[0061] Influence of wave steepness: (1) For twisted blocks and double 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 more likely the protective blocks are 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 this 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 relative period, the larger the instability wave height, and the less likely the protective blocks are to become unstable; when the Irrebaren number is greater than this 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.

[0062] The comprehensive influence of wave period and breakwater slope on the stability of the armor block: the stability number N3 of the block has a good correlation with the Irribarren number ξ reflecting the wave state on the slope.

[0063] Under the same wave steepness, with the increase of the spectral peak rise factor, that is, the spectral type is narrowed, the armor block is more prone to instability, and the instability wave height increases with the decrease of the wave steepness, that is, the larger the wave steepness, that is, the shorter the relative period, the larger the instability wave height, and the armor block is more difficult to be unstable, at the same time, the wave period and the breakwater slope also have an influence on the stability of the armor block, the method provided by the application fully considers the wave height, wave period, slope gradient and spectral peak rise factor of the target sea area when designing the armor block structure, and then selects the armor block structure with the strongest stability, and determines the weight of the armor block structure, so as to realize the purpose of enhancing the stability of the armor block.
