[0044] The technical solutions in the embodiments of the application will be apparently and completely described in combination with the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection scope of the application.

[0045] In the prior method, a large number of high-precision mechanical sensors need to be laid out, which is expensive; the background server needs to have high computing power and large storage space to meet the data collection, analysis, processing and storage requirements in crowded flight time. In order to solve the above technical problems, the application discloses an airport runway structure life evaluation method, device, equipment and medium, which can improve the calculation method of the allowable covering action frequency of the aircraft based on the pavement deformation, accurately evaluate the runway structure life, and judge whether the runway airworthiness performance is good.

[0046] Referring to Figure 1 The embodiment of the application discloses an airport runway structure life evaluation method, which comprises the following steps:

[0047] Step S11, determining the to-be-evaluated position of the airport runway structure life according to the positions of the mechanical sensors pre-installed on the airport runway.

[0048] In the embodiment, first, the mechanical sensors are installed under the pavement panels at the lower left corner of the airport runway based on the numbers of the airport runway, and the mechanical sensors are numbered according to the installation order; wherein, any two adjacent mechanical sensors are separated by four pavement panels; if the mechanical sensors find faults in the self-checking process, the numbers of the mechanical sensors with faults are recorded by the background server, the positions of the mechanical sensors with faults are determined based on the numbers, and the mechanical sensors with faults are replaced or repaired. In a specific embodiment, starting from the end with a smaller number of the airport runway (for example, the runway number is 01 / 19, starting from the 01 end), one mechanical sensor is laid under every four pavement panels at the lower left corner, and the mechanical sensors are numbered in order. The locations of the sensors are recorded. Similarly, based on airport pavement evaluation management regulations and actual airport pavement condition assessment experience, the locations of the mechanical sensors represent the locations where the airport pavement structural lifespan needs to be evaluated. The locations where the airport runway structural lifespan needs to be evaluated are numbered as follows: And each location corresponds one-to-one with the location of the mechanical sensor, that is Location and correspond.

[0049] In addition, all the mechanical sensors on the runway are wired to a back-end server (1), such as Figure 2 As shown (where number 1 represents the mechanical sensor, number 5 represents the backend server (1), and number 6 represents the airport flight arrival and departure information system), the backend server statistically records, collects, and saves the stress, strain, and displacement data of each sensor. The backend server (1) connects to the airport flight arrival and departure information system, and all pavement mechanical sensors remain dormant when there are no flights. When there are flights arriving or departing, the backend server (1) activates all pavement mechanical sensors 1 minute in advance, and obtains the flight type ( ) and the corresponding arrival and departure times. During periods without flights, all mechanical sensors on the airport runway are in a dormant state. The backend server (1) is interconnected with the airport flight arrival and departure information system and the mechanical sensors. When the backend server (1) detects that there will be flights arriving or departing, it activates all mechanical sensors 2 minutes in advance. After receiving the activation command, the mechanical sensors perform a self-check. After the self-check is successful, they are in working condition. If a mechanical sensor malfunction is found during the self-check, the backend server (1) records the mechanical sensor malfunction number and determines the location of the malfunction through the number. The malfunctioning mechanical sensor is then replaced or repaired after the flight. Because the location of the airport runway structure life to be evaluated corresponds one-to-one with the location of the mechanical sensors, the location of the airport runway structure life to be evaluated is determined based on the location of each mechanical sensor pre-installed on the airport runway.

[0050] Step S12: When evaluating the structural life of the target location to be evaluated, the target mechanical sensor is determined based on the pavement surface deformation at the moment of flight landing, and it is determined whether the location of the target mechanical sensor is the target location to be evaluated.

[0051] In this embodiment, an airport runway is used. Taking location as an example, structural life evaluation is conducted. Based on runway engineering management practices, The structural lifespan of a landing gear is affected by the aircraft type and its position on the pavement. The aircraft type influences the load it places on the pavement, and the actual position of the aircraft needs to account for load reduction due to landing gear misalignment. When the aircraft type... After landing, all the mechanical sensors record the deformation of the pavement surface at the moment of landing. One of these mechanical sensors must be among them. The recorded deformation is at its maximum value, at which point there are two operating conditions: mechanical sensor Location Exactly Position and force sensors Location Not for Location.

[0052] When evaluating the structural life of the target location, the deformation of each pavement layer at the moment of flight landing, recorded by all mechanical sensors, is determined. The mechanical sensor corresponding to the largest pavement layer deformation is identified as the target mechanical sensor. Then, it is determined whether the location of the target mechanical sensor corresponds to the target evaluation location. This approach considers the load reduction effect due to the offset of the actual landing gear load application location.

[0053] Step S13: Determine the actual number of times the target location to be evaluated is affected by the aircraft type based on the corresponding judgment results, and determine the allowable number of times the target location to be evaluated is affected.

[0054] In this embodiment, it is assumed that the airport runway structure is within the life evaluation period (during which the runway structure performance and functional performance are intact). When aircraft types land randomly, the deformation pattern of the landing gear on the runway surface at the landing point is the same, that is:

[0055] ;

[0056] In the formula, u represents the pavement deformation under aircraft load. The main landing gear is located at point p. The main landing gear is located at point q. (Note: The original text contains some inconsistencies and inconsistencies. A more accurate translation would require the full context.) Aircraft main landing gear and airport runway When the positions coincide, it is the most unfavorable load position. Due to the randomness of aircraft takeoff and landing positions, if the main landing gear happens to act on the [unclear - possibly a specific location] during a single takeoff and landing... Position, then the aircraft to The coverage effect caused by position does not need to be reduced and is counted as 1. To quantify the effect of the main landing gear on position q, for The degree of coverage caused by location is defined by the damage attenuation coefficient. For model In other words, the expression is:

[0057] ;

[0058] in, model The main landing gear acts at position q. The pavement deformation caused by the location (by number) (Mechanical sensor monitoring); model The main landing gear acts at position q, resulting in pavement deformation at position q.

[0059] If the location of the target force sensor is the target location to be evaluated, then the first actual number of times the target location to be evaluated is subjected to the aircraft type is determined as 1; if the location of the target force sensor is not the target location to be evaluated, then the second actual number of times the target location to be evaluated is subjected to the aircraft type is determined by a second actual number of times formula; the second actual number of times formula is:

[0060] ;

[0061] in, This refers to the second actual number of times it was applied; For aircraft types monitored by mechanical sensors The main landing gear acts on Position Pavement deformation caused by location; For aircraft types monitored by mechanical sensors The main landing gear acts on Position The deformation of the pavement caused by the location.

[0062] Specifically, for When conducting structural life assessments at a location, the effective range of the landing gear load can be determined based on the extent of surface deformation. Based on airport-measured and statistically analyzed aircraft coverage data, flight parameter data for relevant aircraft models, and combined with engineering experience, it is assumed that the landing gear is acting on... The region (the deformation range of the structural layer, the set of all q positions) will affect If structural damage occurs at a certain location, then... Location is affected by aircraft model The actual number of coverage operations can be calculated using the following formula:

[0063] ;

[0064] If the mechanical sensor Location Exactly The location indicates the relative position of the landing site to the location being evaluated. In this respect, it is precisely in the most unfavorable load position, for The coverage effect caused by location does not decrease, that is:

[0065] ;

[0066] If the mechanical sensor Location Not for The location indicates the relative position of the landing site to the location being evaluated. In terms of The coverage effect caused by location will be attenuated, and the damage attenuation coefficient is:

[0067] ;

[0068] In the formula, For model The main landing gear acts on Location, The pavement deformation caused by the location (by number) (Mechanical sensor monitoring); For model The main landing gear acts on Location, The pavement deformation caused by the position (by mechanical sensors) monitor).

[0069] The maximum allowable load-bearing capacity of pavement structures is typically obtained from pavement fatigue equations, the most commonly used being the SN curve, which is usually derived from experimental data and empirical formulas. Although pavement fatigue equations differ between countries, evaluation methods based on pavement fatigue theory share inherent similarities. This application uses the FAA-NCHRP1-26 fatigue equation as a basis to analyze the maximum allowable load-bearing capacity of pavement structures. The FAA-NCHRP1-26 fatigue equation is as follows:

[0070] ;

[0071] As shown in the above formula, the tensile stress at the bottom of the slab is crucial to the fatigue equation value. However, based on actual airport engineering experience, the method of determining the maximum tensile stress at the bottom or within the slab by analyzing the location of the maximum stress is usually affected by various factors, making it impossible to accurately analyze and evaluate the actual pavement fatigue condition. This patent improves the fatigue equation based on the vertical displacement variation of the pavement structure surface layer to calculate the maximum allowable bearing capacity of the pavement structure. The mechanical response changes of the pavement slab under different landing conditions are analyzed, and the fatigue equation of the pavement slab is corrected through finite element simulation to obtain the variation of the maximum tensile stress at the bottom of the slab under different wheel loads (MPa). (MPa) (that is) ) and the maximum vertical displacement of the pavement structure surface layer (mm):

[0072] ;

[0073] Where x is the load applied to the pavement. Based on the two formulas above, we obtain a... and The relational expression is then substituted into the FAA-NCHRP1-26 fatigue equation. According to the Civil Airport Cement Concrete Pavement Design Code (MH / T 5004-2010), the design value of the axial tensile strength is taken. By performing multivariate regression analysis on the mechanical response of the pavement slab under the most unfavorable working condition, a method for calculating the allowable number of actions based on the most unfavorable vertical deformation of the pavement layer can be obtained. The results are as follows:

[0074] ;

[0075] in, The allowable number of loads; u is the actual vertical displacement of the pavement structure under wheel load; e is the base of the natural logarithm; where u is the value in the above formula. This application considers the real-time fatigue damage to the runway caused by different aircraft types and load weights. It monitors pavement deformation in real time using mechanical sensors and simultaneously analyzes and calculates the runway's permissible number of impacts. It eliminates destructive practices such as core drilling in traditional runway life assessments, thus avoiding any damage to the runway. Utilizing runway deformation theory and measured pavement layer deformation values, the lifespan of all runway areas can be quickly and simultaneously calculated. The application improves the calculation method for the permissible number of aircraft impacts based on pavement deformation, overcoming the difficulties and inaccuracies associated with traditional stress-based calculations.

[0076] Step S14: Determine the structural life evaluation value of the target location to be evaluated based on the actual number of actions and the allowed number of actions, and evaluate the structural life of the airport runway based on the structural life evaluation value.

[0077] In this embodiment, if the location of the target mechanical sensor is the target evaluation location, the ratio between the first actual number of actions and the allowed number of actions is determined as the first structural life evaluation value of the target evaluation location; if the location of the target mechanical sensor is the target evaluation location, the ratio between the second actual number of actions and the allowed number of actions is determined as the second structural life evaluation value of the target evaluation location; the sum of each first structural life evaluation value and each second structural life evaluation value determined within a preset evaluation time is determined as the structural life evaluation value of the target evaluation location. Specifically, if the mechanical sensor... Location Exactly Location, then model After this landing, Positional structure lifespan for:

[0078] ;

[0079] Where, 0 < <1, The closer the value is to 1, the better the airport runway. The shorter the remaining lifespan of the position.

[0080] If the mechanical sensor Location Not for Location, then model After this landing, Positional structure lifespan for:

[0081] ;

[0082] Finally, the sum of the first structural life evaluation values ​​and the second structural life evaluation values ​​determined within the preset evaluation time is determined as the structural life evaluation value of the target location to be evaluated.

[0083] Then, based on the structural life evaluation value of each location to be evaluated on the airport runway according to a preset time or number of flights, a corresponding analysis report is generated so as to complete the evaluation of the structural life of the airport runway based on the analysis report; wherein, if the structural life evaluation value is equal to 1, the service life of the location to be evaluated on the airport runway is determined to be 0; the structural life evaluation value is greater than 0 and less than or equal to 1; if the structural life evaluation value increases, the service life of the location to be evaluated on the airport runway decreases.

[0084] In summary, this application first determines the locations to be evaluated for the structural life of the airport runway based on the positions of various mechanical sensors pre-installed on the airport runway. When evaluating the structural life of the target locations, the target mechanical sensors are determined based on the pavement surface deformation at the moment of flight landing, and it is determined whether the location of the target mechanical sensors corresponds to the target location to be evaluated. Based on the corresponding judgment results, the actual number of times the target location to be evaluated is subjected to the aircraft type is determined, and the permissible number of times the target location to be evaluated is determined. Based on the actual number of times the aircraft type is subjected to the aircraft type and the permissible number of times the aircraft type is subjected to the aircraft type, the structural life evaluation value of the target location to be evaluated is determined, and the structural life evaluation value of the airport runway is evaluated based on the structural life evaluation value. This application utilizes runway deformation theory and measured pavement surface deformation values ​​to quickly and simultaneously solve the life of all runway areas, improving the calculation method for the permissible number of aircraft coverage actions based on pavement deformation. It overcomes the disadvantages of traditional methods based on stress calculations, such as high monitoring difficulty and inaccurate measurements, achieving automatic monitoring, real-time alarms, and no manual intervention, thus realizing accurate evaluation of runway structural life.

[0085] Compared to the traditional airport regulations that specify the number of permissible runway operations during the evaluation period, the significant innovation of this application lies in determining the permissible number of runway operations by using sensors to record pavement deformation in real time. This fully considers the fatigue damage caused to the runway by different aircraft types and landing weights, thus overcoming the deficiency of traditional runway life evaluation methods that cannot account for the fatigue damage fluctuations caused by random changes in takeoff and landing weights. Based on the above analysis, airport runways can be designated... Structural life assessment is performed at the location, in order to Taking the model as an example, The formula for evaluating the lifespan of a location structure is:

[0086] ;

[0087] In the formula, For the t-th load action Vertical displacement of the pavement surface layer. Therefore, the designated airport runway under the action of m types of aircraft during the evaluation period. The formula for evaluating the lifespan of a location structure can be expressed as:

[0088] ;

[0089] Similarly, the structural lifespan at any point on an airport runway can be quantitatively expressed by the above formula. As shown in the formula, as the coverage area of ​​the airport runway increases, R increases accordingly, indicating a decrease in the structural lifespan of that area. Theoretically, the structural lifespan at a certain point on the airport runway is 0 < 0. <1, The closer the value is to 1, the better the airport runway. The shorter the remaining service life of the position, the more... If the value is greater than or equal to 1, it indicates that the structural performance of the area has been completely lost and construction and maintenance are required.

[0090] Throughout the process, the backend server (1) automatically programs according to the formula of this application to synchronously analyze and calculate all locations of the airport runway and synchronously generate a runway structure life status analysis report. In a specific embodiment, when the structural life value of a certain monitoring area of ​​the runway reaches 0.99 (this value can be set arbitrarily), the system issues an early warning message and saves the alarm log, which is then stored on the backend server.

[0091] In this way, this application eliminates the drawbacks of traditional methods based on stress calculation, such as high monitoring difficulty and inaccuracy, and achieves automatic monitoring and real-time alarm without manual intervention.
