Description

TECHNICAL FIELD

[0001] The present application relates to the field of bridges, in particular, to a bridge carrying capacity determination, device, storage medium and electronic device. BACKGROUND

[0002] For a newly built bridge, load test is used to check the design and construction quality of the bridge span structure, determine the reliability of the project, provide reliable basis for the smooth operation of the bridge, provide complete initial fingerprint data for long-term monitoring of the bridge, and accumulate experimental data for design and construction of the same type of bridge. Especially for large-span and complex structure bridges, load test is an important means for completion acceptance and quality evaluation. Load test can be used to check the construction quality of the bridge. Load test includes static load test and dynamic load test. Static load test is used for on-site test analysis of bridge structure, while dynamic load test is used as an auxiliary means of static test to supplement and improve the static test scheme. Static load test has the characteristics of strong feasibility and is mainly used for completion acceptance of new bridges or evaluation work when the operation status and carrying capacity performance of the bridge cannot be determined. However, static load test method requires a large amount of manpower and material resources, has high cost, long test period, and may cause serious damage to bridge components during the test, affecting normal traffic, and thus is difficult to popularize. Compared with static load test, dynamic load test has smaller scale, less cost, shorter test period and simple operation. However, dynamic load test has certain limitations in application. Due to the relatively low dynamic test level, the corresponding data measured in the test has large deviation from the theoretically calculated data, which cannot meet the specified accuracy requirement.

[0025] First, the related technologies involved in the present application are described:

[0026] The load of a bridge refers to the collective name of various possible loads that should be considered in the design of a bridge structure, including dead load, live load and other loads.

[0027] The method embodiments provided in the embodiments of the present application can be executed in a mobile terminal, a computer terminal or a similar computing device. Taking the case of running on a mobile terminal, Figure 1 is a hardware structural block diagram of a mobile terminal of a method for determining the carrying capacity of a bridge according to an embodiment of the present application. As shown in Figure 1 , the mobile terminal can include one or more Figure 1Only one is shown in the diagram. A processor 102 (which may include, but is not limited to, a microprocessor MCU or a programmable logic device FPGA, etc.) and a memory 104 for storing data are also shown. The mobile terminal may further include a transmission device 106 for communication functions and an input / output device 108. Those skilled in the art will understand that... Figure 1 The structure shown is for illustrative purposes only and does not limit the structure of the mobile terminal described above. For example, the mobile terminal may also include components that are more... Figure 1 The more or fewer components shown, or having the same Figure 1 The different configurations shown.

[0028] The memory 104 can be used to store computer programs, such as application software programs and modules, like the computer program corresponding to the bridge load-bearing capacity determination method in this embodiment of the invention. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, thereby implementing the above-described method. The memory 104 may include high-speed random access memory and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory.

[0029] The transmission device 106 is used to receive or send data via a network.

In one example, the transmission device 106 includes a Network Interface Controller (NIC), which can connect to other network devices via a base station to communicate with the Internet. In another example, the transmission device 106 may be a Radio Frequency (RF) module, used for wireless communication with the Internet.

[0030] This embodiment provides a method for determining the load-bearing capacity of a bridge. Figure 2 This is a flowchart of a method for determining the bearing capacity of a bridge according to an embodiment of the present invention, such as... Figure 2 As shown, the process includes the following steps:

[0031] Step S202: Obtain multiple first loads on the bridge during a first time period, wherein the first loads include the weight acting on the bridge;

[0032] In step S204, the first structural change data corresponding to each first load in the first time period is obtained, and a plurality of first structural change data is obtained.

[0033] In step S206, the target deviation curve is generated by using the plurality of first loads and the plurality of first structural change data, wherein the target deviation curve includes the correspondence between the first load and the corresponding first structural change data.

[0034] In step S208, the bearing capacity of the bridge in the first time period is determined based on the target deviation curve and the original deviation curve, wherein the original deviation curve includes the correspondence between the second load and the corresponding second structural change data.

[0035] Optionally, the first time period can be flexibly set based on the actual scene, or can be the current time period. For example, when it is necessary to detect the bearing capacity of the bridge in the current time period (for example, the time period of the last month, the time period of the last week, or the time period of the day), the plurality of first loads of the bridge in the current time period is obtained, and the first structural change data corresponding to each first load of the bridge in the current time period is obtained.

[0036] Optionally, the first load includes the weight acting on the bridge, and is real-time in time, and the position of each weight is variable, and one weight corresponds to one position on the bridge. For example, the bridge is divided into 5 sections, and the weight carried by each section is obtained in real time when the vehicle travels through the 5 sections. Since the vehicle is moving, the weight distribution position is different, and the deviation of the sensor is also different. One or more sensors need to be set in each section to obtain the structural change data corresponding to the weight carried by each section. The structural change data includes but is not limited to deformation data of the bridge under the action of one weight, vibration data of the bridge under the action of one weight, and displacement data of the bridge under the action of one weight.

[0037] Optionally, the original deviation curve can be a deviation curve drawn under the optimal bearing capacity of the bridge when the bridge is just built. It can also be a deviation curve drawn in any time period of use of the bridge. As a reference, the change of the bearing capacity of the bridge between two time periods can be determined, so as to determine the bearing capacity of the bridge in the first time period.

[0038] The execution subject of the above steps can be a terminal, a server, a specific processor arranged in the terminal or the server, or a processor or processing device arranged independently of the terminal or the server, but is not limited thereto.

[0039] By the above steps, by acquiring a plurality of first loads of the bridge in a first time period, wherein the first load includes the weight acting on the bridge; acquiring first structural change data corresponding to each of the first loads of the bridge in the first time period, obtaining a plurality of first structural change data; generating a target offset curve using a plurality of first loads and a plurality of first structural change data, wherein the target offset curve includes the correspondence between the first load and the corresponding first structural change data; determining the carrying capacity of the bridge in the first time period based on the target offset curve and the original offset curve, wherein the original offset curve includes the correspondence between the second load and the corresponding second structural change data. Since in the above method, when determining the carrying capacity of the bridge in the first time period, only the target offset curve is determined by using the acquired first load of the bridge in the first time period, the corresponding first structural change data, and the carrying capacity of the bridge is determined from the target offset curve and the original offset curve, without interrupting the traffic on the bridge, and there is no limitation in the application process. Therefore, the problem of interrupting the traffic on the bridge, high cost and large detection error in the related art when detecting the carrying capacity of the bridge can be solved, and the effect of reducing the detection cost of the bridge and improving the detection accuracy is achieved.

[0040] In one example embodiment, acquiring a plurality of first loads of the bridge in a first time period includes: acquiring the weight acting on the bridge at a plurality of preset positions in the above first time period; determining the average of a plurality of the weight at each of the above preset positions as the load at each of the above preset positions to obtain a plurality of first loads. In this embodiment, a plurality of preset positions can be flexibly set based on the length of the bridge, for example, a longer bridge is divided into 5 segments, a shorter bridge is divided into 3 segments, etc. Since the vehicle is moving, the load at each position will be different. The average of a plurality of loads at each position is determined as the first load at each position, which can accurately determine the first load at each position.

[0041] In one example embodiment, acquiring the first structural change data corresponding to each of the first loads of the bridge in the above first time period to obtain a plurality of first structural change data includes: acquiring the first structural change data corresponding to the first load by the sensor in the above first time period, wherein the sensor is arranged at a plurality of preset positions on the above bridge. In this embodiment, one or more sensors can be arranged at each preset position, and in the case of including a plurality of sensors, the average of a plurality of structural data acquired by a plurality of sensors can be determined as the first structural data of each preset position. Thus, the accuracy of acquiring the first structural data is increased.

[0042] In an example embodiment, the target deviation curve is generated by using the plurality of first loads and the plurality of first structural change data, including: determining the corresponding first structural change data of each of the first loads within the first time period; and plotting the corresponding relationship between each of the first loads and the corresponding first structural change data to generate the target deviation curve. In this embodiment, for example, when the first load is 10 tons, the deviation of the bridge is 4 mm, and when the first load is 100 tons, the deviation of the bridge is 8 mm. This embodiment can intuitively reflect the corresponding relationship between each load and the corresponding structural change data within the first time period by plotting the target deviation curve.

[0043] In an example embodiment, before determining the carrying capacity of the bridge within the first time period based on the target deviation curve and the original deviation curve, the method further includes: obtaining a plurality of second loads of the bridge within a second time period, wherein the second loads include the weight acting on the bridge, and the second time period is earlier than the first time period; obtaining second structural change data corresponding to each of the second loads within the second time period, to obtain a plurality of second structural change data; and plotting the corresponding relationship between each of the second loads and the corresponding second structural change data to generate the original deviation curve. In this embodiment, the corresponding relationship between each load and the corresponding structural change data within the second time period can be intuitively reflected by plotting the original deviation curve.

[0044] In an example embodiment, determining the carrying capacity of the bridge within the first time period based on the target deviation curve and the original deviation curve includes: searching for a plurality of second loads in the original deviation curve, which have the same position and weight as the plurality of first loads in the bridge; determining a plurality of second structural change data corresponding to the plurality of second loads; and determining the carrying capacity of the bridge within the first time period by using the plurality of second structural change data and the plurality of first structural change data.

[0045] Optionally, the determination of the bearing capacity of the bridge in the first time period based on the plurality of second structural change data and the plurality of first structural change data comprises: for each of the first structural change data and the corresponding second structural change data, obtaining a plurality of deviation rates by performing the following operations: calculating a first difference value between a first deviation value in the first structural change data and a second deviation value in the corresponding second structural change data, wherein the first deviation value and the second deviation value are used to represent the change value of the structural change of the bridge; determining a ratio between the first difference value and the second deviation value as the deviation rate; and determining the bearing capacity of the bridge in the first time period based on an average value of the plurality of deviation rates. Optionally, the determination of the bearing capacity of the bridge in the first time period based on the average value of the plurality of deviation rates comprises: determining a second difference value between a preset value and the deviation rate as the bearing capacity of the bridge in the first time period. For example, when the first load in the deviation curve is 10 tons, the first deviation value of the bridge is 4 mm; when the second load in the original deviation curve is 10 tons, the second deviation value of the bridge is 3.5 mm; then the first difference value can be calculated as 0.5 mm, and the deviation rate is 0.14. When the first load in the deviation curve is 20 tons, the deviation value of the bridge is 5 mm; when the second load in the original deviation curve is 10 tons, the deviation value of the bridge is 4 mm; then the first difference value can be calculated as 1 mm, and the first deviation rate is 0.33. Then the average value of 0.14 and 0.33 is 0.24, and the bearing capacity of the bridge in the first time period is (1-0.24)*100% of the original bearing capacity, i.e. 76%. In this embodiment, the preset value can be a natural number, for example, 1 or 0.8. For example, 0.24 is used to represent the attenuation value of the bearing capacity of the bridge, and 1 minus the average value is the change of the bearing capacity of the bridge, i.e. how much the current bearing capacity is compared with the previous bearing capacity, and 1 indicates that the bearing capacity of the bridge can reach 100%, which is the most ideal bearing capacity. The final output is still a percentage, which evaluates the change of the bearing capacity, for example, 100% indicates that the bearing capacity does not change, 80% indicates that the bearing capacity is only 80% of the previous bearing capacity, and the deviation rate is 20%. This embodiment can accurately determine the bearing capacity of the bridge by calculating the average value of the deviation rate of the bridge.

[0046] The application will be described in detail below with reference to specific embodiments:

[0047] The application provides a system for evaluating the bearing capacity of a bridge, which comprises: a bridge deck load distribution detection system, a bridge structure monitoring system, and a data analysis system (including a processor for processing data); and mainly comprises the following steps:

[0048] S1, periodically (for example, one month) generate a load-deviation curve (corresponding to the deviation curve in the above). Periodically (for example, one minute) collect the bridge deck load distribution detection system output of the bridge dynamic load data (corresponding to the first load in the above); synchronously collect the sensor data output by the bridge structure monitoring system (including the first structure change data in the above); record the deviation rate of the sensor real-time data and the zero point data; generate the bridge dynamic load and sensor deviation curve (corresponding to the target deviation curve in the above).

[0049] Optionally, the zero point data can be determined by the following method: the bridge deck load distribution detection system detects the dynamic load of the bridge, and when the load is 0, that is, there is no vehicle on the bridge, the sensor zero point recording signal is given; when the bridge structure monitoring system receives the sensor zero point recording signal, the output signal of each sensor in the bridge structure monitoring system is recorded; the sensor output signal at this moment is taken as the sensor zero point.

[0050] S2, the first load-deviation curve generated is taken as the initial curve of the bridge (corresponding to the original deviation curve in the above). The load in the initial curve can be obtained as shown in the following table, for example: Figure 3 At 9 o'clock in the morning, 48 large trucks are orderly driven to the fixed position for symmetry and eccentricity detection, and the load test of the large bridge is carried out in turn, so as to comprehensively evaluate the real bearing capacity of the large bridge and test the automobile impact coefficient of the corresponding control part of the large bridge structure. At the same time, the technicians test the bearing capacity of the bridge from multiple angles.

[0051] S3, the load-deviation curve generated periodically is analyzed for deviation with the initial load-deviation curve of the bridge, specifically including:

[0052] 1) Select a comparison point, for example, a group of uniformly distributed dynamic load points;

[0053] 2) Read the deviation under the dynamic load from the current load-deviation curve and the original load-deviation curve;

[0054] 3) Calculate the deviation value of the deviation under the load;

[0055] 4) Add all the deviation values and take the average;

[0056] S4, use the deviation degree to represent the change of the bearing capacity of the bridge.

[0057] In summary, the embodiment does not need to interrupt the traffic of the bridge when detecting the bearing capacity of the bridge. And the measurement can be based on the actual vehicle flow, and the bearing capacity of the bridge can be monitored for a long time.
