[0048] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0049] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0050] Figure 1 is a flow chart of a method for evaluating the safety performance of a water cushion pond according to an exemplary embodiment. Figure 1 As shown, the method comprises the following steps:

[0051] In step S11, a three-dimensional numerical simulation result of the plunge pond is obtained based on the three-dimensional geometric model.

[0052] The three-dimensional numerical simulation results may include values ​​such as pressure, water-air interface changes, and turbulent viscosity changes of the cross section.

[0053] In step S12, the damage characteristic level of the water cushion pond is determined according to the hydrodynamic characteristics of the complex flow field of the water cushion pond and the mechanical properties of the concrete on the flow surface.

[0054] It is understandable that typical damage to a cushion pond may include flow surface damage types such as abrasion, spalling and cracks, and the damage characteristic levels can be divided according to the different damage types, for example, can be divided into five levels: level I, level II, level III, level IV and level V.

[0055] In step S13, the relationship between the change of hydraulic elements and the damage of the plunge pond is determined according to the three-dimensional numerical simulation results and the loss characteristic level.

[0056] Among them, the hydraulic elements may include influencing factors such as flow velocity, flow, pressure, pulsating pressure and turbulent kinetic energy. The relationship between the changes in the hydraulic elements and the damage of the water cushion pond may refer to mathematical modeling based on the results of the three-dimensional data simulation and different damage characteristic levels, using the result equation (for example, using the three-dimensional numerical simulation results as the independent variable and the damage characteristic level as the dependent variable to construct the model), so as to clearly identify the location where the water cushion pond is more seriously damaged.

[0057] In step S14, different safety levels of the cushion pond are determined according to the relationship between the loss characteristic level and the change of the hydraulic element and the damage of the cushion pond. The different safety levels are used to evaluate different safety performances of the cushion pond.

[0058] The security level may be determined according to actual conditions. For example, it may include three security levels: safe, low risk, and high risk. It may also be divided more finely as needed, which is not limited in the present disclosure.

[0059] In the above technical scheme, the three-dimensional numerical simulation results of the cushion pond are obtained based on the three-dimensional geometric model, and the damage characteristic level of the cushion pond is determined according to the hydrodynamic characteristics of the complex flow field of the cushion pond and the mechanical properties of the concrete on the flow surface. The relationship between the change of hydraulic elements and the damage of the cushion pond is determined according to the three-dimensional numerical simulation results and the loss characteristic level. Different safety levels of the cushion pond are determined according to the loss characteristic level and the relationship between the change of hydraulic elements and the damage of the cushion pond. The different safety levels are used to evaluate the different safety performances of the cushion pond. Through the above technical scheme, the safety performance of the cushion pond can be evaluated by combining the evaluation indicators such as the simulation results of the three-dimensional model, the damage characteristic level and the relationship between hydraulic factors and losses, and the safety hazards of the cushion pond can be discovered, thereby improving the design, construction and operation management level of the cushion pond to a certain extent.

[0060] Figure 2 is a flow chart of a method for evaluating the safety performance of a water cushion pond according to an exemplary embodiment. Figure 2 As shown, the step S11 of obtaining the three-dimensional numerical simulation result of the plunge pool based on the three-dimensional geometric model may include the following steps:

[0061] Step S111, constructing a three-dimensional geometric model of the plunge pool according to a set geometric scale using fluid mechanics software;

[0062] Step S112, simulating different working conditions in the three-dimensional geometric model of the plunge pond to obtain the three-dimensional numerical simulation results.

[0063] It is understandable that simulation data such as pressure, changes in water-air interface and changes in turbulent viscosity of the cross section can be obtained through the fluid mechanics software, wherein the fluid mechanics software can be a modeling software commonly used in the industry, such as Fluent or Flow 3D, and the present disclosure does not limit this.

[0064] Figure 3 is a flow chart of a method for evaluating the safety performance of a water cushion pond according to an exemplary embodiment. Figure 3 As shown, step S112 may include the following steps:

[0065] Step S1121, obtaining the change of at least one hydraulic element under different working conditions;

[0066] Step S1122, determining the position where the maximum pulsating pressure of the cushion pond acts according to the change of the hydraulic element; the position is used to characterize the influence of the change on the damage of the cushion pond.

[0067] Among them, the different operating conditions may include the following situations: different upstream water levels of the reservoir, different cushion pond water levels and different numbers and methods of opening of flood discharge orifices; the hydraulic elements may include flow velocity, flow, pressure, pulsating pressure and turbulent kinetic energy and other elements.

[0068] It can be understood that each simulation condition corresponds to a three-dimensional simulation result. For example, when the upstream water level of the cushion pond is increased, the location of the maximum pulsating pressure is obtained through the Fluent software. For example, the three-dimensional simulation result image of the Fluent software can intuitively represent the different pressures at different positions of the cushion pond. The greater the pressure in the simulation result, the more serious the damage to the cushion pond.

[0069] Figure 4 is a flow chart of a method for evaluating the safety performance of a water cushion pond according to an exemplary embodiment. Figure 4 As shown, the step S12 of determining the damage characteristic level of the water cushion pond according to the hydrodynamic characteristics of the complex flow field of the water cushion pond and the mechanical properties of the concrete on the flow surface may include the following steps:

[0070] Step S121, determining damage information of the flow surface and damage quantification parameters of the apparent concrete on the flow surface by statistically analyzing data of typical damage characteristics.

[0071] The damage information includes information such as damage type, damage range and loss location, and the damage quantification parameters include parameters such as aggregate exposure ratio, size and depth and crack length.

[0072] Step S122, determining the degree of abrasion of the bottom plate of the water cushion pond according to the concrete abrasion evaluation standard.

[0073] Step S123, taking the flow surface concrete block as the minimum unit indicator, and determining the damage characteristic level within the flow surface range of the water cushion pond according to the damage information of the flow surface, the damage quantification parameter of the apparent concrete of the flow surface and the degree of abrasion of the bottom plate of the water cushion pond.

[0074] It can be understood that by combining the hydrodynamic characteristics of the complex flow field of the cushion pond with the mechanical properties of the concrete flow surface, and by identifying the main characteristics and distribution patterns of typical cushion pond flow surface damage such as abrasion, spalling and cracks, a damage characteristic level can be proposed. For example, it can be divided into five levels: I, II, III, IV and V, corresponding to normal, basically normal, slightly abnormal, moderately abnormal and severely abnormal conditions, respectively.

[0075] Figure 5 is a flow chart of a method for evaluating the safety performance of a water cushion pond according to an exemplary embodiment. Figure 5 As shown, the step S14 of determining different safety levels of the plunge pool according to the relationship between the loss characteristic level and the change of the hydraulic element and the damage of the plunge pool may include the following steps:

[0076] Step S141, using a quantitative method to perform a quantitative assessment on the safety index; the quantitative method includes an expert scoring method or a risk matrix analysis method;

[0077] Step S142, comprehensively considering the quantified safety index, the relationship between the change of hydraulic elements and the damage of the cushion pond, and the loss characteristic level, to determine different safety levels of the cushion pond.

[0078] For example, in one possible implementation, the safety level may include three levels, namely, safe, low risk and high risk, by comprehensively considering the expert scores and the loss characteristic levels. The safety level may include the case where the loss characteristic level of the cushion pond is level I, the low risk level may include the case where the loss characteristic level is level II or level III, and the high risk level may include the case where the loss characteristic level is level IV or level V.

[0079] In the above technical scheme, the three-dimensional numerical simulation results of the cushion pond are obtained based on the three-dimensional geometric model, and the damage characteristic level of the cushion pond is determined according to the hydrodynamic characteristics of the complex flow field of the cushion pond and the mechanical properties of the concrete on the flow surface. The relationship between the change of hydraulic elements and the damage of the cushion pond is determined according to the three-dimensional numerical simulation results and the loss characteristic level. Different safety levels of the cushion pond are determined according to the loss characteristic level and the relationship between the change of hydraulic elements and the damage of the cushion pond. The different safety levels are used to evaluate the different safety performances of the cushion pond. Through the above technical scheme, the safety performance of the cushion pond can be evaluated by combining the evaluation indicators such as the simulation results of the three-dimensional model, the damage characteristic level and the relationship between hydraulic factors and losses, and the safety hazards of the cushion pond can be discovered, thereby improving the design, construction and operation management level of the cushion pond to a certain extent.
