Description

Technical Field

[0001] This application relates to the field of bridge repair and reinforcement construction, specifically to a new method, device, equipment, and computer-readable storage medium for adjusting the longitudinal displacement of bearings. Background Technology

[0002] Supports are installed between the main girder (superstructure) and the piers (substructure) of a bridge to transfer structural loads. For concrete cable-stayed bridges, the effects of temperature and shrinkage / creep cannot be ignored. To reduce secondary internal forces in the structure, supports are often designed as longitudinal movable supports.

[0003] For concrete cable-stayed bridges that have been in operation for many years, due to the large span and long main beam length, the shrinkage and creep effects are significant, resulting in numerous bearing defects. These defects mainly manifest as increased longitudinal eccentricity of the bearings, even exceeding the design displacement limit of the bearings, severe wear of bearing components, and permanent damage to the bearing body, rendering the bearings unable to function properly or limiting their functionality.

[0004] In related technologies, bearings are replaceable components. When bearing defects are severe and affect normal function, bearing replacement can be performed. Currently, in bridge bearing replacement, the common practice is to install a new bearing with the same longitudinal displacement as the old one. However, this bearing replacement does not improve the longitudinal eccentricity problem of the bearing. If the bearing operates in an eccentric state for a long time, it will affect the normal function of the bearing. Summary of the Invention

[0031] Figure 2 This is a schematic diagram of the hardware structure of the new support longitudinal displacement adjustment device involved in the embodiment of this application. Detailed Implementation

[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0034] In a first aspect, embodiments of this application provide a method for adjusting the longitudinal displacement of a new support.

[0035] In one embodiment, reference is made to Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the new support longitudinal displacement adjustment method of this application. Figure 1 As shown, the method for adjusting the longitudinal displacement of the new support includes:

[0036] S100: Based on the finite element calculation model of the bridge structure, calculate the theoretical value of Dsh of the longitudinal displacement of the bridge bearing to be replaced due to shrinkage and creep effect since the bridge was completed.

[0037] S200: Based on the actual longitudinal displacement Dsp of the bridge bearing to be replaced and the theoretical value Dsh of the longitudinal displacement generated by the bridge bearing to be replaced, calculate the longitudinal displacement Dx of the new bridge bearing.

[0038] In this embodiment, based on the finite element calculation model of the bridge structure, the theoretical value Dsh of the longitudinal displacement of the bridge bearing to be replaced due to shrinkage and creep effect since the bridge's completion is calculated. For bridges that have been in operation for many years, the shrinkage and creep effect of the concrete has been largely completed. During the bearing replacement construction, the longitudinal eccentricity of the bearing is caused by the intensified shrinkage and creep. Therefore, the theoretical value Dsh of the longitudinal displacement of the bridge bearing to be replaced due to shrinkage and creep effect is subtracted from the actual longitudinal displacement Dsp of the bridge bearing to be replaced measured on site to correct the longitudinal displacement Dx of the new bridge bearing. This ensures that the new bearing can be correctly installed in the predetermined position, maintaining the stability and safety of the bridge structure. The adjusted longitudinal displacement of the new bearing is more in line with actual needs, improves the longitudinal eccentricity problem of the newly replaced bearing, and can effectively ensure the normal use function of the new bearing. The longitudinal displacement adjustment in the bearing replacement construction is a simple and practical construction method with broad application prospects in bearing replacement construction.

[0039] Furthermore, in one embodiment, step S200 includes the following steps:

[0040] S201: Based on the actual longitudinal displacement Dsp of the bridge bearing to be replaced, the theoretical value Dsh of the longitudinal displacement generated by the bridge bearing to be replaced, and the correction coefficient K1 within the set time period of bearing model monitoring, the longitudinal displacement Dx of the new bridge bearing is calculated.

[0041] In this embodiment, the actual longitudinal displacement Dsp of the bridge bearing to be replaced is the actual longitudinal displacement of the bearing to be replaced, which is the data obtained from actual measurement. The theoretical value Dsh of the longitudinal displacement generated by the bridge bearing to be replaced is the theoretical value of the longitudinal displacement generated by the bridge bearing to be replaced, which is the expected value derived from design and calculation. The correction coefficient K1 within the set time period of bearing model monitoring is the correction coefficient within the set time period of bearing model monitoring. This coefficient is used to adjust the theoretical value to be closer to the actual situation.

[0042] Specifically, the formula for calculating the longitudinal displacement Dx of the new bridge bearing is Dx=Dsp-Dsh×K1.

[0043] Furthermore, in one embodiment, step S201 includes the following steps:

[0044] S201-1: Monitor the longitudinal displacement change value ΔXts of the support to be replaced within a set time period, and monitor the temperature change value ΔTts within the set time period.

[0045] S201-2: Based on the finite element calculation model of the bridge structure, calculate the longitudinal displacement ΔDts of the bearing to be replaced under the condition of temperature change ΔTts within the set time period.

[0046] S201-3: Based on the longitudinal displacement change value ΔXts of the support to be replaced within a set time period and the longitudinal displacement calculated value ΔDts under the working condition of the temperature change value ΔTts within the set time period, calculate the correction coefficient K1 for the support model monitoring within the set time period.

[0047] S201-4: Based on the actual longitudinal displacement Dsp of the bridge bearing to be replaced, the theoretical value Dsh of the longitudinal displacement generated by the bridge bearing to be replaced, and the correction coefficient K1 within the set time period of bearing model monitoring, the longitudinal displacement Dx of the new bridge bearing is calculated.

[0048] In this embodiment, to calculate the longitudinal displacement Dx of the new bridge bearing, we need to follow these steps: monitor the change in longitudinal displacement ΔXts of the bearing to be replaced within a set time period. Simultaneously, monitor the temperature change ΔTts within the same time period. Using a finite element model of the bridge structure, simulate the calculated longitudinal displacement ΔDts of the bearing to be replaced under the condition of temperature change ΔTts. Based on the actual monitored longitudinal displacement change ΔXts and the simulated longitudinal displacement calculation ΔDts, we can calculate the correction coefficient K1. The formula for calculating the correction coefficient K1 is: K1 = ΔXts / ΔDts. This correction coefficient reflects the difference between the actual displacement and the theoretically calculated displacement, and is used for subsequent calculation adjustments. Finally, we use the correction coefficient K1, the actual longitudinal displacement Dsp of the bearing to be replaced, and the theoretical longitudinal displacement Dsh of the bridge bearing to be replaced to calculate the longitudinal displacement Dx of the new bridge bearing. The calculation formula is: Dx=Dsp-Dsh×K1, where K1=ΔXts / ΔDts.

[0049] Furthermore, in one embodiment, step S200 includes the following steps:

[0050] S201: Based on the actual longitudinal displacement Dsp of the bridge bearing to be replaced, the theoretical value Dsh of the longitudinal displacement generated by the bridge bearing to be replaced, and the bearing age correction coefficient K2, calculate the longitudinal displacement Dx of the new bridge bearing.

[0051] In this embodiment, to calculate the longitudinal displacement Dx of the new bridge bearing, we need to consider the actual longitudinal displacement Dsp of the bearing to be replaced, the theoretical longitudinal displacement Dsh of the bridge bearing to be replaced, and the bearing age correction factor K2. Here, the bearing age correction factor K2 is a coefficient used to consider the influence of the bearing's service life on the displacement. In this way, we can comprehensively consider the influence of theoretical values, actual values, and the bearing's service life, thereby calculating a more accurate longitudinal displacement of the new bridge bearing.

[0052] Specifically, the calculation formula is: Dx=Dsp-Dsh×K2, where K2=1.0 according to the operation time of the bridge structure from completion. If the operation period is greater than 20 years, K2=1.3; if the operation period is less than or equal to 10 years, K2=1.3; and the intermediate operation period can be linearly interpolated.

[0053] Furthermore, in one embodiment, step S200 includes the following steps:

[0054] S201: Based on the actual longitudinal displacement Dsp of the bridge bearing to be replaced, the theoretical value of the longitudinal displacement Dsh generated by the bridge bearing to be replaced, and the permanent deformation of the bearing to be replaced Dsun, calculate the longitudinal displacement Dx of the new bridge bearing.

[0055] In this embodiment, to calculate the longitudinal displacement Dx of the new bridge bearing, we need to consider the actual longitudinal displacement Dsp of the bearing to be replaced, the theoretical value Dsh of the longitudinal displacement generated by the bridge bearing to be replaced, and the permanent deformation Dsun of the bearing to be replaced due to damage. In this way, we can comprehensively consider the theoretical value, the actual value, and the influence of bearing damage, thereby calculating a more accurate longitudinal displacement of the new bridge bearing.

[0056] Specifically, the calculation formula is: Dx = Dsp - Dsh - Dsun.

[0057] Furthermore, in one embodiment, S100 includes the following steps:

[0058] S101: Based on the finite element calculation model of the bridge structure and the bridge's geometry, material properties, boundary conditions, and all relevant loads since the bridge's completion, calculate the theoretical value Dsh of the longitudinal displacement of the bearing to be replaced since the bridge's completion.

[0059] In this embodiment, a finite element model of the bridge structure is established based on the actual geometry of the bridge. The various parts of the bridge are defined in the model, including beams, bearings, and piers. Correct material properties, such as elastic modulus, Poisson's ratio, and density, are specified for each part of the model. Boundary conditions for the bridge are defined, such as fixed constraints for piers and sliding constraints for bearings. All relevant loads from the bridge's completion to the present are applied. Finite element calculation software is used to calculate the stress, strain, and displacement of the bridge under various loads. The longitudinal displacement of the bearing to be replaced is extracted from the calculation results. The extracted displacements are accumulated or averaged to obtain the theoretical value Dsh of the longitudinal displacement of the bearing to be replaced since the bridge's completion. Through the above steps, we can use the finite element calculation model of the bridge structure and related data to calculate the theoretical value Dsh of the longitudinal displacement of the bearing to be replaced since the bridge's completion. This theoretical value will be used for the subsequent calculation of the longitudinal displacement of the new bridge bearing.

[0060] Furthermore, in one embodiment, S100-1 includes the following steps:

[0061] S101-1: All relevant loads since the completion of the bridge, including external and internal loads that have affected the bridge structure since its completion.

[0062] In this embodiment, since the bridge's completion, all loads affecting the bridge structure mainly fall into three categories: permanent loads, variable loads, and accidental loads. Permanent loads include the structure's self-weight, prestressing, soil weight, and lateral soil pressure. These loads remain essentially constant throughout the bridge's design service life and directly impact the safety and durability of the bridge structure. Variable loads include vehicle loads, pedestrian loads, wind force, temperature influence, and bearing skin friction. These loads may change during the bridge's design service life, dynamically affecting the bridge structure. Accidental loads include seismic forces and impacts from ships or drifting objects. These loads may not occur during the bridge's design service life, but if they do, they can significantly impact the bridge structure.

[0063] In another embodiment, the present application provides a complete description of the method for adjusting the longitudinal displacement during support replacement:

[0064] Step 1: Before replacing the bearing, measure the actual longitudinal displacement Disp between the center of the upper bearing plate and the center of the lower bearing plate of the bearing to be replaced on site.

[0065] Step 2: On-site inspection of the longitudinal bridge-direction permanent deformation of the bearing to be replaced, and measurement of the permanent deformation Dsun of the bearing to be replaced;

[0066] Step 3: Monitor continuously for three days to determine the longitudinal displacement change ΔXts between the center of the upper bearing plate and the center of the lower bearing plate of the support to be replaced, and record the corresponding temperature change ΔTts.

[0067] Step 4: Based on the design drawings, establish a finite element calculation model of the bridge structure;

[0068] (1) Calculate the theoretical value of the longitudinal displacement Dsh of the bearing to be replaced due to shrinkage and creep effects from the time the bridge was completed until the present time.

[0069] (2) Calculate the longitudinal displacement ΔDts of the bridge structure under the working condition of temperature change ΔTts;

[0070] Step 5: Adjust the longitudinal displacement Dx of the new support replacement as follows;

[0071] (1) Determine the support model correction coefficient K1 = ΔXts / ΔDts;

[0072] (2) Determine the bearing life correction factor K2. Based on the bridge structure's operation time from completion, K2 = 1.0 for operation time greater than 20 years, K2 = 1.3 for operation time less than or equal to 10 years, and linear interpolation for intermediate operation time.

[0073] (3) The longitudinal displacement Dx of the new support replacement is:

[0074] Dx = Dsp (actual longitudinal displacement between the center of the upper bearing plate and the center of the lower bearing plate of the bearing to be replaced) - Dsh (longitudinal displacement value Dsh generated by the bearing to be replaced) × K1 × K2 - Dsun (permanent deformation of the bearing to be replaced due to damage).

[0075] In the formula, Dsun and Dsp have the same deformation direction and are positive, while Dsun and Dsp have opposite deformation directions and are negative.

[0076] After calculating the longitudinal displacement Dx required for the replacement of the new support, a new support that meets the requirement of this longitudinal displacement Dx is designed, and the old support is replaced. The specific replacement construction method is as follows:

[0077] Step 1: Before removing the original support components, mark the position of the pier corresponding to the center line of the lower support plate, mark the position of the main beam structure corresponding to the center line of the upper support plate, and measure the actual longitudinal displacement Disp between the center of the upper support plate and the center of the lower support plate of the support to be replaced on site.

[0078] Step 2: Install temporary supports and jacks, and remove the upper and lower connecting components of the support;

[0079] Step 3: Use jacks to lift the support until the displacement is achieved, then lock the temporary support.

[0080] Step 4: Remove the main components of the support and perform rust removal and anti-corrosion treatment on the original embedded parts of the support;

[0081] Step 5: Install the new support. First, align the center line of the new support's lower plate with the center line of the original support's lower plate, then install the lower plate connecting components to achieve the anchoring requirements.

[0082] Step 6: Adjust the longitudinal displacement Dx of the new support according to the calculation, adjust the initial longitudinal displacement of the new support, and lock the longitudinal movement constraint of the support after the adjustment is in place.

[0083] Step 7: Use jacks to lower the beam back to the original design elevation of the support, ensuring that the support is evenly stressed, and then remove the temporary support;

[0084] Step 8: Install the upper bearing plate connecting components of the new support to achieve the anchoring requirements and release the longitudinal constraint of the support;

[0085] Step 9: Confirm that the longitudinal movement of the support is in good condition, remove all temporary supports, jacks and other equipment, and complete the support replacement construction.

[0086] Secondly, this application also provides a device for adjusting the longitudinal displacement of a new bridge bearing. The device includes: a theoretical longitudinal displacement calculation module, which calculates the theoretical longitudinal displacement Dsh of the bridge bearing to be replaced due to shrinkage and creep effects since the bridge's completion, based on a finite element model of the bridge structure; and a new bridge bearing longitudinal displacement calculation module, which calculates the longitudinal displacement Dx of the new bridge bearing based on the actual longitudinal displacement Dsp of the bridge bearing to be replaced and the theoretical longitudinal displacement Dsh generated by the bridge bearing to be replaced.
