Description

Technical Field

[0001] The present application relates to the technical field of bridge detection, for example, to a method and device for determining an area suitable for testing a bridge state using a temperature load. Background Art

[0002] In order to promptly discover potential safety hazards, such as structural damage, material aging, design defects, etc., it is usually necessary to test the bearing capacity of the bridge so that necessary maintenance, reinforcement or renovation measures can be taken when problems are found to ensure the safety of the bridge during use.

[0003] The evaluation of the bearing capacity state of bridges in the prior art mainly includes the appearance survey method and the load test method. At present, the pressure load test is basically the main test method. Unfortunately, although the pressure load test can directly reflect the real stiffness and key cross-sectional internal forces of the bridge, it has many problems such as interruption of traffic, high cost, complex scheme, poor safety, and possible irreversible damage and collapse. Therefore, it is necessary to consider a bridge test method that can replace the pressure load equivalently. Since the most convenient way to implement temperature load on the bridge is to load it with sunlight, and the sunlight that can be obtained in different regions is different, when considering using temperature load to replace pressure load equivalently, it is first necessary to determine the area suitable for testing the bridge state using temperature load, and then perform temperature load test on the suitable area. Otherwise, the bridge bearing capacity state test can only be carried out by traditional pressure load or appearance survey method. However, the existing bridge bearing capacity state test does not determine the area suitable for testing the bridge state using temperature load, nor does it use the temperature load method for testing. Therefore, it is urgent to first be able to determine the area suitable for testing the bridge state using temperature load, so as to reasonably use temperature load to test the bridge bearing capacity state.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0025] Combination Figure 1 As shown, the embodiment of the present disclosure provides a method for determining an area suitable for testing a bridge state using a temperature load, comprising:

[0026] Step S101, obtaining a target area from a region set. The target area is an area to be determined whether it is suitable for testing the bridge state using temperature load. The region set includes multiple target areas.

[0027] In some embodiments, the region input by the user is accepted and stored in the region set to realize the generation or update of the region set. In some embodiments, the region is a geographical location region. Optionally, the geographical location region includes a province, for example, Sichuan Province, Guangdong Province, etc. Optionally, the geographical location region includes a city, for example, Chongqing City, Shenzhen City, etc. Optionally, the geographical location region includes a district, a county, etc., for example, Yuzhong District, Yubei District, etc. In some embodiments, the target region is the region receiving the user input. In some embodiments, the target region is any region in the region set. In some embodiments, the target region is the first region in the region set.

[0028] Step S102, obtaining sunshine information corresponding to the target area. The sunshine information includes the sunshine conditions of the target area within a preset time period. For example, the preset time period is the past N years, or the past year, or the past half year, etc., where N is a positive integer greater than 1.

[0029] Step S103, determining the pressure load range corresponding to the target area according to the sunshine information.

[0030] Step S104, determining whether the target area is suitable for testing the bridge state using the temperature load according to the pressure load range corresponding to the target area.

[0031] The method for determining an area suitable for testing the state of a bridge using a temperature load provided by the embodiment of the present disclosure is adopted, by obtaining the sunlight exposure of the target area within a preset time period, and based on this, determining the pressure load range corresponding to the target area. In this way, the temperature change caused by sunlight can be used to calculate the pressure load range that the target area may correspond to. Since there are clear requirements for pressure load in testing the bearing capacity state of a bridge in the prior art, it is possible to determine whether the target area is suitable for testing the state of a bridge using a temperature load from a set of areas including multiple target areas according to the pressure load range corresponding to the target area.

[0032] In an embodiment of the present disclosure, a method for determining an area suitable for testing a bridge condition using a temperature load is implemented by a server or a computer.

[0033] Further, obtaining the sunshine information corresponding to the target area includes: using the target area to perform a table lookup operation in a preset sunshine information table to obtain the sunshine information corresponding to the target area. The sunshine information table stores the area information, the sunshine information, and the corresponding relationship between the area information and the sunshine information. The area information includes the target area. In this way, the sunshine information corresponding to the target area can be quickly obtained, so as to determine whether the area is suitable for testing the health status of the bridge using temperature load.

[0034] In some embodiments, the sunshine information includes multiple sunshine duration periods, the light intensity corresponding to each sunshine duration period, and the bridge deformation displacement corresponding to each sunshine duration period. The multiple sunshine duration periods are multiple sunshine duration periods within a preset time period. For example, the sunshine duration period is the sunshine duration period of each day in the past year. For another example, the sunshine duration period is the sunshine duration period of each month in the past N years.

[0035] In one embodiment, the sunshine information table is obtained in the following manner: using weather forecasts, the light intensity of each area in the area set in a plurality of sunshine duration periods within a preset time period is obtained, and the corresponding relationship between the light intensity and the area is stored in a preset sunshine information table. A CCD sensor is set at the center position of a randomly selected bridge in the area, and the deformation displacement of the bridge corresponding to each sunshine duration period is obtained by using the CCD sensor, and the corresponding relationship between the light intensity and the area is stored in the preset sunshine information.

[0036] Combination Figure 2 As shown, further, determining the pressure load range corresponding to the target area according to the sunshine information includes:

[0037] Step S201: Determine the lighting stability corresponding to the target area.

[0038] Step S202: Determine a temperature load reference value that can be obtained in the target area according to the sunshine duration periods and the light intensity corresponding to each sunshine duration period.

[0039] Step S203: determining the pressure load range corresponding to the target area according to the illumination stability corresponding to the target area, the temperature load reference value, and the bridge deformation displacement corresponding to each sunshine duration period.

[0040] In some embodiments, in step S201, the sunshine information is obtained by accepting and storing multiple sunshine duration periods input by the user, the light intensity corresponding to each sunshine duration period, and the bridge deformation displacement corresponding to each sunshine duration period.

[0041] In some embodiments, in step S201, a light sensor collects light intensity and records the corresponding time to obtain multiple sunshine duration periods and the light intensity corresponding to each sunshine duration period, and receives and stores the deformation displacement of the bridge corresponding to each sunshine duration period input by the user. Optionally, the light sensor starts timing when it detects that the light intensity reaches a set threshold, and ends timing when it detects that the light intensity does not reach the set threshold, thereby obtaining the sunshine duration period. When the light sensor uploads the light intensity, it records the upload time, thereby obtaining the month and year corresponding to the sunshine information. In the above manner, it is possible to obtain sunshine year information, sunshine month information, multiple sunshine duration periods corresponding to the sunshine month information, and light intensity corresponding to each sunshine duration period.

[0042] In some embodiments, step S201 determines the illumination stability corresponding to the target area, including: using the target area to perform a table lookup operation in a preset illumination stability data table to obtain the illumination stability corresponding to the target area. The illumination stability data table stores the area, illumination stability, and the mapping relationship between the area and illumination stability.

[0043] For example, Table 1 is an example table of illumination stability data. As can be seen from Table 1, the corresponding stability can be queried from region 1 as 23.54, the stability can be queried from region 4 as 1.00, and the stability can be queried from region 3 as 0.57. In some embodiments, the closer the stability is to the preset value, the more stable it is. In some embodiments, the preset value is 1, and the smaller the absolute value of the difference between the stability of the region and 1, the more stable it is.

[0044] Table 1 Example of light stability data

[0045] area Light stability Region 1 23.54 Region 2 17.66 Region 3 0.57 Region 4 1.00 Region 5 6.98

[0046] When the light stability data table is preset, the light stability is obtained in the following way:

[0047] Obtain the length values GSC of the light duration periods for each month in multiple years ij and the quantity values GS of the light duration periods for each month in multiple years in . GSC ij is the length of the j-th light duration period in the i-th month of each year, where 1 ≤ i ≤ 12 and j is a positive integer. GS i is the quantity value of the light duration periods in the i-th month of each year. For example, obtain the light duration periods for each month in the three years 2010 / 2015 / 2020, and respectively obtain the length values and quantity values of the light duration periods for each month in the three years. For example, GSC in 2010 123 is the length of the 3rd light duration period in December 2010, and GSC in 2015 74 is the length of the 4th light duration period in July 2015. In January 2020, 23 light duration periods are monitored, then GS in 2020 1 is the quantity value of the light duration periods in January 2020, and this quantity value is 23. Optionally, the light duration period is obtained by starting to time when the light intensity reaches a set threshold and ending the timing when it is monitored that the light intensity does not reach the set threshold, that is, the light intensity within the light duration period needs to reach the set threshold.

[0048] For each year, calculate to obtain the annual light stability parameter for each year. Among them, NC is the annual light stability parameter, α is a preset first weight, α > 0, β is a preset second weight, β > 0, YGC i is the reference threshold of the length of the light duration period in the preset i-th month, and YG i is the reference threshold of the quantity of the light duration periods in the preset i-th month. The annual light stability parameter obtained in the above way takes into account the different monthly light differences and weighted combines the light duration and the monthly light frequency, and can effectively reflect the annual light stability situation. Optionally, β > α. Since the quantity value of the light duration periods can reflect the light stability better than the length of the light duration period, by making the threshold related to the quantity value of the light duration periods relatively higher, the light stability of the area can be better evaluated.

[0049] Calculate to obtain the light stability corresponding to the target area. Among them, NC max is the largest annual light stability parameter among the annual light stability parameters of each year, NC min is the smallest annual light stability parameter among the annual light stability parameters of each year, NC lastis the annual light stability parameter for the last year, NC first is the annual light stability parameter for the first year, δ is the preset value, δ>0. The light stability obtained in the above way not only takes into account the difference in light between different months, and weightedly combines the duration of light and the light frequency of the month, but more importantly, takes into account the time span of multiple years, making the evaluation of light stability more accurate and reliable.

[0050] In some embodiments, step S202 determines the temperature load reference value that can be obtained for the target area according to the sunshine duration period and the light intensity corresponding to each sunshine duration period, including:

[0051] According to the duration of the sunshine duration and its corresponding light intensity, a table lookup operation is performed in a preset temperature load data table to obtain a temperature load reference value that can be obtained in the target area; the temperature load data table stores the duration of the sunshine duration, the light intensity, and the mapping relationship between the duration and the light intensity and the temperature load reference value. In some embodiments, each sunshine duration corresponding to the target area corresponds to a temperature load reference value.

[0052] Combination Figure 3 As shown, in some embodiments, step S203 determines the pressure load range corresponding to the target area according to the illumination stability corresponding to the target area, the temperature load reference value, and the bridge deformation displacement corresponding to each sunshine duration period, including:

[0053] Step S301, using the illumination stability and temperature load reference values ​​corresponding to the target area, adjusting the deformation displacement of the bridge corresponding to each sunshine duration period, and obtaining the adjusted bridge deformation displacement reference values ​​for each sunshine duration period.

[0054] Step S302, determining the pressure load range corresponding to the target area according to the bridge deformation displacement reference values ​​adjusted for each sunshine duration period.

[0055] In some embodiments, step S301 uses the illumination stability and temperature load reference values ​​corresponding to the target area to adjust the bridge deformation displacement corresponding to each sunshine duration period, and obtains the bridge deformation displacement reference values ​​adjusted for each sunshine duration period, including:

[0056] Step S3011, calculate J p =γ×(WHZCK p -YSWH), and obtain the distance adjustment value. p is the distance adjustment value corresponding to the pth sunshine duration period of the target area, γ is the stability weight corresponding to the target area, WHZCK pis the temperature load reference value corresponding to the pth sunshine duration period corresponding to the target area, YSWH is the preset temperature load standard value, and p is a positive integer. Among them, γ is obtained by the following method: using the light stability corresponding to the target area to perform a table lookup operation in the preset stability weight data table to obtain the stability weight corresponding to the target area; the stability weight data table stores light stability, stability weight, and the mapping relationship between stability weight and light stability.

[0057] Step S3012, adding the distance adjustment value corresponding to the p-th sunshine duration period corresponding to the target area and the bridge deformation displacement corresponding to the p-th sunshine duration period corresponding to the target area to obtain the bridge deformation displacement reference values ​​adjusted for each sunshine duration period.

[0058] Since the deformation displacement of the bridge is usually obtained through image recognition by CCD sensors, no matter whether it is uploaded by the user or directly used with the recognized data, the deformation displacement obtained may not be the maximum displacement. In addition, the displacement is also affected by temperature in addition to light. The same lighting time and intensity may also lead to different temperature loads due to different temperatures, and the lighting time period may not be able to be reproduced in the same way. Its stability must be considered to ensure that the test requirements can be met during actual testing. Through the above correction method, the influence of light stability on the test is taken into account, and the influence of displacement data collection and temperature on the theoretical temperature load is reduced, so that the obtained displacement data is more suitable for subsequent pressure load range determination.

[0059] In some embodiments, step S302 determines the pressure load range corresponding to the target area according to the bridge deformation displacement reference values ​​adjusted for each sunshine duration period, including:

[0060] The largest bridge deformation displacement reference value among the bridge deformation displacement reference values ​​adjusted for each sunshine duration period is determined as the bridge deformation displacement final value. The bridge deformation displacement final value is added to the preset first deviation value to obtain the first pressure load deformation value, and the bridge deformation displacement final value is subtracted from the preset second deviation value to obtain the second pressure load deformation value. The first pressure load corresponding to the first pressure load deformation value is obtained, and the second pressure load corresponding to the second pressure load deformation value is obtained. The range between the second pressure load and the first pressure load is determined as the pressure load range corresponding to the target area.

[0061] Optionally, obtaining the first pressure load corresponding to the first pressure load deformation value and obtaining the second pressure load corresponding to the second pressure load deformation value are both achieved by looking up a table. Specifically, the pressure load deformation value is used to perform a table lookup operation in a preset pressure load table to obtain the pressure load corresponding to the pressure load deformation value; the pressure load table stores the pressure load deformation value, the pressure load, and the mapping relationship between the pressure load deformation value and the pressure load.

[0062] Since the materials and / or structures of the bridges may be different, the above method determines the maximum bridge deformation displacement reference value as the final value of the bridge deformation displacement, and determines the final range in combination with the preset deviation value. The pressure load range can be flexibly adjusted by setting the deviation value, thereby increasing the scope of application of this solution and determining whether more types of bridges belong to the area suitable for bearing capacity status evaluation under temperature load.

[0063] Optionally, determining whether the target area is suitable for testing the bridge state using a temperature load according to the pressure load range corresponding to the target area includes: determining whether the pressure load range corresponding to the target area includes a preset standard load range. If the pressure load range corresponding to the target area includes the preset standard load range, it is determined that the target area is suitable for testing the bridge state using a temperature load. If the pressure load range corresponding to the target area does not include the preset standard load range, it is determined that the target area is not suitable for testing the bridge state using a temperature load.

[0064] In some embodiments, the pressure load range corresponding to the target area includes a preset standard load range. It can be understood that the preset standard load range belongs to the pressure load range corresponding to the target area, that is, the preset standard load range is a subset of the pressure load range corresponding to the target area.

[0065] Optionally, determining whether the target area is suitable for testing the bridge state using a temperature load according to the pressure load range corresponding to the target area includes: determining whether the pressure load range corresponding to the target area is the same as a preset standard load range. If the pressure load range corresponding to the target area is the same as the preset standard load range, it is determined that the target area is suitable for testing the bridge state using a temperature load. If the pressure load range corresponding to the target area is different from the preset standard load range, it is determined that the target area is not suitable for testing the bridge state using a temperature load.

[0066] In some embodiments, after determining whether the target area is suitable for testing the bridge state using temperature load according to the pressure load range corresponding to the target area, the method further includes: obtaining a similar illumination area of ​​the target area in the area set, wherein the similar illumination area is an area with illumination conditions similar to those of the target area.

[0067] When it is determined that the target area is suitable for testing the bridge state using the temperature load, the similar illumination area is determined as an area suitable for testing the bridge state using the temperature load. When it is determined that the target area is not suitable for testing the bridge state using the temperature load, the similar illumination area is determined as an area not suitable for testing the bridge state using the temperature load.

[0068] In some embodiments, obtaining the similar illumination area of ​​the target area in the area set includes: using the target area to perform a table lookup operation in a preset similar area table to obtain a candidate similar area corresponding to the target area; the similar area table stores the target area, the candidate similar area, and the mapping relationship between the target area and the candidate similar area. Then, the candidate similar area in the area set is determined as the similar area of ​​the target area.

[0069] Optionally, when there are still areas in the area set whose suitability for testing the bridge condition using temperature load has not been determined, any area in the area whose suitability for testing the bridge condition using temperature load has not been determined is re-determined as a target area for determination.

[0070] The above method can greatly speed up the speed of determining the area suitable for testing the bridge status using temperature load, quickly determine the similar area according to the target area, and do not need to traverse and calculate the areas in the area set, which improves efficiency and reduces memory overhead. It is only necessary to first determine whether the target area is suitable for testing the bridge status using temperature load, and then quickly find the similar area related to the target area by looking up the table, so that the target area and its similar areas are determined. In this way, when there are many areas in the area set, the area suitable for testing the bridge status using temperature load can be determined quickly.

[0071] Optionally, after determining whether the target area is suitable for testing the bridge state using a temperature load according to the pressure load range corresponding to the target area, it also includes: storing the area suitable for testing the bridge state using a temperature load in a preset area database. Or, adding a mark to the area in the area set that is suitable for testing the bridge state using a temperature load. The mark is used to indicate that the bridge state is suitable for testing the bridge state using a temperature load. In this way, it is convenient for users to quickly understand the area where the bridge state can be tested using a temperature load.

[0072] In some embodiments, the above method can be implemented by an intelligent terminal such as a server or a computer. In some embodiments, the bridge is a reinforced concrete box girder bridge. The server or computer can determine the area where the health status of the reinforced concrete box girder bridge can be tested using a temperature load according to the method provided by the embodiment of the present disclosure.

[0074] The device for determining an area suitable for testing the state of a bridge using a temperature load provided by the embodiment of the present disclosure is used to obtain the sunlight exposure of the target area within a preset time period, and based on this, determine the pressure load range corresponding to the target area. In this way, the temperature change caused by sunlight can be used to calculate the pressure load range that the target area may correspond to. Since there are clear requirements for pressure load in testing the bearing capacity of bridges in the prior art, it is possible to determine whether the target area is suitable for testing the state of a bridge using a temperature load from a set of areas including multiple target areas based on the pressure load range corresponding to the target area.
