Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of port engineering, and in particular to a method and system for calculating overtopping of a sloping dike under the action of a swell. BACKGROUND

[0002] In coastal engineering, the sloping dike is an important wave protection structure, and its overtopping directly affects the safety of the area behind the dike. Under the condition of storm surge or far sea wave transmission, the swell has a long period and large energy, and is easy to cause significant water bulging in front of the sloping dike, resulting in a dramatic increase in overtopping, which may cause the dike top to overflow, the armor block to be unstable, and even the dike body to be damaged as a whole, seriously threatening the safety of personnel and facilities behind the dike.

[0003] The patent with publication number CN112629597B provides a dike overtopping measurement system. The overtopping monitoring server analyzes the real-time flow data and rainfall to determine the real-time overtopping. The existing overtopping calculation method is mainly based on short-period wind wave conditions and does not fully consider the effect of long-period swell. Moreover, it relies on empirical parameters. Although it is suitable for conventional wind wave conditions, it does not adequately consider the shallow water effect and wave steepness of long-period swell, and the calculation result often underestimates the actual overtopping. In addition, the overtopping mechanism of swell varies significantly under different armor types, slopes, and water depths. The existing method cannot accurately cover complex conditions through a unified calculation formula.

[0004] In summary, the existing overtopping calculation method has a large error in the calculation result compared to the actual overtopping, and it is difficult to cover multiple working conditions.

[0005] Therefore, it is of great significance to develop a method and system for calculating the overtopping of a sloping dike under the action of a swell to improve the working condition coverage and the accuracy of the calculation result. SUMMARY

[0020] Further, a calculation formula for determining the initial value of the correction parameter according to the target value of the wave steepness factor is:

[0021] ;

[0022] Where λ represents the steepness factor, C represents the correction parameter and C≧0.6, L0 represents the deep water wavelength, and H0 represents the deep water wave height.

[0023] Furthermore, in step S5, determining the corrected overtopping amount based on the basic overtopping amount and the wave steepness factor includes: calculating the corrected overtopping amount based on the calculated value of the wave steepness factor and the basic overtopping amount; when the difference between the corrected overtopping amount and the actual overtopping amount is greater than or equal to a preset threshold, adjusting the initial value of the correction parameter to obtain the adjusted value of the correction parameter, and determining the calculated value of the wave steepness factor based on the adjusted value of the correction parameter, until the difference between the corrected overtopping amount and the actual overtopping amount is less than the preset threshold.

[0024] Furthermore, the corrected overtopping amount is calculated based on the calculated value of the wave steepness factor and the basic overtopping amount, using the following formula:

[0025] q'=λq;

Specifically, the structural and water depth parameters of the target sloping breakwater are used to ensure that the model can accurately reproduce the core structure and water depth environment of the target sloping breakwater, and the application of swell conditions based on the wave field parameters ensures that the experimental conditions are consistent with the actual swell conditions faced by the target sloping breakwater. The wave steepness factor is calculated by directly relying on the actual overwave amount determined by the physical model, instead of fixed empirical values ​​or theoretical estimates. This ensures that the difference between the corrected overwave amount and the actual overwave amount is less than a preset threshold. The corrected overwave amount is more in line with the actual scenario, which improves the working condition coverage capability of the overwave amount calculation method and the accuracy of the calculation results.

[0044] The specific embodiments of the present invention will be described below.

[0045] To address the shortcomings of existing wave overtopping calculation methods, which often fail to cover diverse operating conditions and exhibit significant errors, this invention obtains the structural parameters, wave field parameters, and water depth parameters of the target sloping breakwater. It then calculates the foundation wave overtopping based on these parameters.

The difference between the corrected wave overtopping and the actual wave overtopping is less than a preset threshold. This wave overtopping calculation method offers high operating condition coverage and provides highly accurate results.

[0046] Example 1

[0047] This invention provides a method for calculating the wave overtopping volume of a sloping breakwater under surging wave action. Figure 1 This is a flowchart of a method for calculating the overtopping volume of a sloping breakwater under the action of surging waves, provided by an embodiment of the present invention. Figure 1 As shown, the specific steps include the following:

[0048] S1. Obtain the structural parameters, wave field parameters, and water depth parameters of the target slope embankment.

[0049] A target sloping breakwater refers to a specific sloping breakwater where the overtopping volume under swell action needs to be calculated. Structural parameters are parameters reflecting the structural characteristics of the target sloping breakwater itself, such as revetment parameters and superelevation. Wave field parameters are parameters reflecting the intensity and periodicity of swell action at the target sloping breakwater location, such as spectral peak period and significant wave height. Water depth parameters refer to the actual water depth in front of the target sloping breakwater, representing the vertical distance from the seabed to the calm water surface on the wave-facing side of the breakwater, used to reflect the aquatic environmental conditions at the breakwater's location. Structural parameters are extracted by consulting the engineering design drawings of the target sloping breakwater, and wave field parameters and water depth parameters are extracted by consulting long-term marine meteorological and hydrological reports of the sea area where the target sloping breakwater is located, providing a complete data foundation for subsequent calculations.

[0050] S2. Calculate the foundation overtopping amount based on the wave field parameters, the structural parameters, and the water depth parameters.

[0051] Specifically, this includes: inputting parameters such as the superelevation of the dike crest, the revetment parameters, the spectral peak period, the significant wave height, and the water depth into the foundation overtopping calculation model; the foundation overtopping calculation model calculates and outputs the foundation overtopping based on the input data.

[0052] The basic overtopping volume calculation model is as follows:

[0053] ;

[0054] Where q represents the basic wave quantity, H c This indicates the superelevation of the embankment crest, where A and m are empirical parameters, K is the influence coefficient of the revetment structure among the revetment parameters, and H... 1 / 3 T represents the effective wave height; T0 represents the spectral peak period; h represents the thickness of the dry-laid rubble or dry-laid strip stone revetment in the revetment parameters; t represents time; d represents the water depth parameter; and g represents the gravitational acceleration.

[0055] The baseline overcurrent is determined by multi-dimensional parameter calculation. It comprehensively covers the influencing factors of swell, structure, and water environment through three types of parameters: structural parameters, wave field parameters, and water depth parameters. This avoids the reference value deviation caused by parameter omissions in traditional methods and lays a reliable foundation for the correction process.

[0056] S3. Determine the physical model of the target slope embankment based on its structural parameters and water depth parameters. Apply surging conditions to the physical model based on the wave field parameters of the target slope embankment, and determine the actual overtopping amount based on the physical model.

[0057] A physical model refers to a scaled-down model, constructed according to the actual parameters of the target embankment, including key features such as slope and revetment structure. This model is installed in a wave flume testing system to reproduce real-world wave-crossing scenarios. A surge condition refers to a test scenario reproduced in a wave flume that matches the actual surge conditions faced by the target embankment; its core characteristics are determined by wave field parameters.

[0058] The wave-generating system of the wave flume was activated, and the wave field parameters of the target sloping breakwater were input to generate waves consistent with the actual swell characteristics. These waves were continuously applied to the wave-facing surface of the physical model to reproduce the target swell conditions. A water collection device was installed behind the physical model breakwater to collect the overrushing water. The actual overrush volume was calculated by combining the width of the water collection flume and the effective measurement time. Each set of conditions was repeated at least three times, and the average value was taken as the final actual overrush volume to avoid errors from single measurements. The physical model was determined by structural and water depth parameters, replicating the core structure and water environment characteristics of the target sloping breakwater. By loading the swell conditions with wave field parameters, the actual swell conditions were reproduced, avoiding data distortion caused by differences between the model and the prototype, and providing a reliable measured benchmark for subsequent wave steepness factor calculations.

[0059] S4. Calculate the wave steepness factor based on the actual wave overtopping amount.

[0060] Among them, the wave steepness factor is a coefficient used to correct for the shallow water backwater effect of long-period swells, and its calculation formula is as follows:

[0061] ;

[0062] λ represents the steepness factor, C represents the correction parameter and C≧0.6, L0 represents the deep water wavelength, and H0 represents the deep water wave height.

[0063] The deep-water wavelength and deep-water wave height are calculated based on wave field parameters, specifically including: calculating the deep-water wavelength based on the spectral peak period; determining the water depth conditions based on the deep-water wavelength and water depth parameters; and determining the deep-water wave height based on the significant wave height when the water depth conditions are deep water.

[0064] Deep-water wavelength refers to the wavelength determined by the swell period in deep-water environments, and is a core parameter reflecting the propagation characteristics of long-period swells. The formula for calculating deep-water wavelength based on the spectral peak period is as follows:

[0065] ;

[0066] Where L0 represents the deep-water wavelength, g represents the gravitational acceleration, and T0 represents the spectral peak period.

[0067] Deep-water wave height refers to the original wave height of a swell in a deep-water environment, assuming the waves are not affected by shallow water. It is a key parameter for quantifying the energy of swells in deep water and needs to be calculated based on the effective wave height in the wave field parameters when the water depth is deep. For example, H0 = 1.05H 1 / 3 .

[0068] The spectral peak period is extracted from the acquired wave field parameters. The deep-water wavelength is calculated based on the spectral peak period. The water depth parameter of the target slope breakwater is extracted, and the water depth parameter d is compared with the deep-water wavelength L0. If d ≥ L0 / 2, it is determined to be a deep-water condition; otherwise, it is a shallow-water condition. Under deep-water conditions, the significant wave height is extracted from the wave field parameters, and the deep-water wave height is calculated based on the significant wave height. Deep-water wavelength and deep-water wave height are key parameters for calculating the wave steepness factor. The deep-water wavelength is accurately calculated using formulas, and the deep-water wave height is determined in conjunction with the deep-water scenario, providing accurate deep-water parameters for calculating the wave steepness factor.

[0069] Specifically, calculating the wave steepness factor based on the actual overtopping amount includes: calculating a target value of the wave steepness factor based on the actual overtopping amount and the base overtopping amount; determining an initial value of the correction parameter based on the target value of the wave steepness factor; and determining a calculated value of the wave steepness factor based on the initial value of the correction parameter.

[0070] The target value of the wave steepness factor refers to the ideal wave steepness factor obtained by dividing the actual overflight amount (as the corrected overflight amount) by the base overflight amount, in order to make the corrected overflight amount approximate the actual overflight amount. Based on the target value of the wave steepness factor, the above formula is used... The initial value of the correction parameter can be calculated. Since the value of the correction parameter is not less than 0.6, when the calculated initial value of the correction parameter is less than 0.6, it is set to 0.6. The final determined initial value of the correction parameter is substituted into the wave steepness factor calculation formula to obtain the calculated value of the wave steepness factor. The target value of the wave steepness factor is directly determined by the difference between the actual overtopping amount and the baseline overtopping amount, ensuring that the wave steepness factor is calculated to closely match the actual overtopping effect, guaranteeing accuracy from the source. The initial value of the correction parameter is not randomly set, but is obtained by inverse solving the target value of the wave steepness factor. This avoids the blind adjustment of parameters and ensures that the initial value is not too small, thus preventing insufficient wave steepness factor and ensuring coverage of shallow water backwater effects.

[0071] S5. Determine the corrected overtopping amount based on the basic overtopping amount and the wave steepness factor, wherein the difference between the corrected overtopping amount and the actual overtopping amount is less than a preset threshold.

[0072] The corrected overtopping amount refers to the overtopping amount obtained after correcting the basic overtopping amount using the wave steepness factor, and it must meet the difference requirement with the actual overtopping amount. The preset threshold is a preset error standard used to determine whether the difference between the corrected overtopping amount and the actual overtopping amount meets the standard. If the difference is less than the preset threshold, it means that the accuracy of the corrected overtopping amount meets the requirements. If the difference is greater than or equal to the preset threshold, the wave steepness factor needs to be adjusted and the corrected overtopping amount needs to be recalculated.

[0073] Specifically, determining the corrected overtopping amount based on the basic overtopping amount and the wave steepness factor includes: calculating the corrected overtopping amount based on the calculated value of the wave steepness factor and the basic overtopping amount; when the difference between the corrected overtopping amount and the actual overtopping amount is greater than or equal to a preset threshold, adjusting the initial value of the correction parameter to obtain the adjusted value of the correction parameter, and determining the calculated value of the wave steepness factor based on the adjusted value of the correction parameter, until the difference between the corrected overtopping amount and the actual overtopping amount is less than the preset threshold.

[0074] Based on the calculated wave steepness factor and the basic overtopping amount obtained above, the corrected overtopping amount is calculated according to the formula q'=λq, where q' represents the corrected overtopping amount, q represents the basic overtopping amount, and λ represents the steepness factor. When the difference between the corrected overtopping amount and the actual overtopping amount is greater than or equal to a preset threshold, the initial value of the correction parameter is adjusted to obtain the adjusted value of the correction parameter. For example, when the corrected overtopping amount is less than the actual overtopping amount, it indicates insufficient correction, and the adjusted value of the correction parameter is obtained by increasing the initial value of the correction parameter. When the corrected overtopping amount is greater than the actual overtopping amount, it indicates overcorrection, and the adjusted value of the correction parameter is obtained by decreasing the initial value of the correction parameter. The adjusted value of the correction parameter is substituted into the wave steepness factor calculation formula to obtain the calculated value of the wave steepness factor. The corrected overtopping amount is calculated based on the calculated value of the wave steepness factor, and the difference between the corrected overtopping amount and the actual overtopping amount is compared again. By repeatedly adjusting and correcting the wave slope factor, calculating the corrected overtopping amount, and comparing the difference between the corrected and actual overtopping amounts, the process continues until the difference is less than a preset threshold. Finally, a corrected overtopping amount that meets the accuracy requirements is determined. Through iterative processes of adjusting correction parameters, optimizing the wave slope factor, and adjusting the corrected overtopping amount, the final corrected overtopping amount accurately reflects the intensity of the surge wave overtopping. This provides reliable data for the safety design of sloping embankments.

[0075] This embodiment obtains the structural parameters, wave field parameters, and water depth parameters of the target sloping breakwater; calculates the foundation overtopping based on these parameters; determines the physical model of the target sloping breakwater based on its structural and water depth parameters; applies swell conditions to the physical model based on the wave field parameters; determines the actual overtopping based on the physical model; calculates the wave steepness factor based on the actual overtopping; and determines the corrected overtopping based on the foundation overtopping and wave steepness factor, ensuring that the difference between the corrected overtopping and the actual overtopping is less than a preset threshold. The use of the target sloping breakwater's structural and water depth parameters ensures that the model accurately reflects the core structure and water depth environment of the target sloping breakwater, while applying swell conditions based on the wave field parameters guarantees that the experimental conditions are consistent with the actual swell conditions faced by the target sloping breakwater. The wave steepness factor is calculated by directly relying on the actual overwave amount determined by the physical model, instead of fixed empirical values ​​or theoretical estimates. This ensures that the difference between the corrected overwave amount and the actual overwave amount is less than a preset threshold. The corrected overwave amount is more in line with the actual scenario, which improves the working condition coverage capability of the overwave amount calculation method and the accuracy of the calculation results.

[0076] In addition, calculating the wave steepness factor based on the actual overtopping amount includes: calculating a target value of the wave steepness factor based on the actual overtopping amount and the basic overtopping amount; determining an initial value of the correction parameter based on the target value of the wave steepness factor; and determining a calculated value of the wave steepness factor based on the initial value of the correction parameter. Determining the corrected overtopping amount based on the basic overtopping amount and the wave steepness factor includes: calculating the corrected overtopping amount based on the calculated value of the wave steepness factor and the basic overtopping amount; when the difference between the corrected overtopping amount and the actual overtopping amount is greater than or equal to a preset threshold, adjusting the initial value of the correction parameter to obtain an adjusted value of the correction parameter, and determining a calculated value of the wave steepness factor based on the adjusted value, until the difference between the corrected overtopping amount and the actual overtopping amount is less than the preset threshold. Calculating the target value of the wave steepness factor using the actual overtopping amount and the basic overtopping amount ensures accurate calculation direction from the source. Simultaneously, dynamically adjusting the correction parameter based on the difference between the corrected overtopping amount and the actual overtopping amount accurately compensates for the deviation between the basic overtopping amount and the actual overtopping amount, solving the problem that traditional methods with fixed parameters cannot adapt to different working conditions.
