Description

Technical Field

[0001] The present application relates to the field of bridge repair and reinforcement construction, and specifically to a new bearing longitudinal displacement adjustment method, device, equipment and computer-readable storage medium. Background Art

[0002] The bearing is set between the bridge main beam (superstructure) and the pier (substructure) to transfer the structural load. For the concrete cable-stayed bridge structure, the temperature and shrinkage creep effects cannot be ignored. In order to reduce the secondary internal force of the structure, the bearing is mostly set as a longitudinal movable bearing.

[0003] For concrete cable-stayed bridges that have been in operation for many years, due to the large span of the cable-stayed bridge, the long main beam length, and the significant shrinkage creep effect, there are many bearing diseases, which are mainly manifested in aggravated longitudinal eccentricity of the bearing, even exceeding the design displacement limit of the bearing, severe wear of the bearing components, permanent damage to the bearing body, and other diseases. The bearing can no longer work normally or its function is limited.

[0004] In the related technology, the bearing is a replaceable component. When the bearing is seriously damaged and has affected its normal function, the bearing replacement construction can be carried out. At present, in the replacement construction of bridge bearings, the common practice is to install the new bearing with the same longitudinal displacement as the old bearing. The bearing replacement construction does not improve the longitudinal eccentricity problem of the bearing. The bearing works in an eccentric state for a long time, which will affect the normal use 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 the present application. DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0034] In a first aspect, an embodiment of the present application provides a new method for adjusting the longitudinal displacement of a support.

[0035] In one embodiment, referring to Figure 1 , Figure 1 This is a schematic diagram of the flow chart of the first embodiment of the novel support longitudinal displacement adjustment method of the present application. Figure 1 As shown, the new bearing longitudinal displacement adjustment method includes:

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

[0037] S200: Calculate 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 value Dsh of the longitudinal displacement generated by the bridge bearing to be replaced.

[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 the shrinkage creep effect from the completion of the bridge to the present is calculated. For bridges that have been in operation for many years, the shrinkage creep effect of the concrete has been basically completed. During the bearing replacement construction process, the longitudinal eccentricity of the bearing is caused by the intensified shrinkage creep. Therefore, the actual longitudinal displacement Dsp of the bridge bearing to be replaced measured on site is subtracted from the theoretical value Dsh of the longitudinal displacement of the bridge bearing to be replaced due to the shrinkage creep effect to correct the longitudinal displacement Dx of the new bridge bearing to ensure that the new bearing can be correctly installed in the predetermined position to maintain the stability and safety of the bridge structure. The adjusted longitudinal displacement of the new bearing is more in line with actual needs, which 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 is adjusted during the bearing replacement construction. The construction method is simple and practical, and has broad application prospects in bearing replacement construction.

[0039] Furthermore, in one embodiment, in S200, the following steps are included:

[0040] S201: Calculate the longitudinal displacement Dx of the new bridge bearing 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 the bearing model monitoring.

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

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

[0043] Furthermore, in one embodiment, in S201, the following steps are included:

[0044] S201-1: monitoring a longitudinal displacement change value ΔXts of the bearing to be replaced within a set time period, and monitoring a 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 value ΔDts of the bearing to be replaced under the temperature change value ΔTts within the set time period;

[0046] S201-3: Calculate the correction coefficient K1 of the bearing model monitoring within the set time period based on the longitudinal displacement change value ΔXts of the bearing to be replaced within the set time period and the longitudinal displacement calculated value ΔDts under the temperature change value ΔTts within the set time period;

[0047] S201-4: Calculate the longitudinal displacement Dx of the new bridge bearing 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 the bearing model monitoring.

[0048] In this embodiment, in order to calculate the longitudinal displacement Dx of the new bridge bearing, we need to follow the following steps to monitor the longitudinal displacement change value ΔXts of the bearing to be replaced within a set time period. At the same time, monitor the temperature change value ΔTts within the set time period. Use the finite element calculation model of the bridge structure to simulate the calculated longitudinal displacement value ΔDts of the bearing to be replaced under the working condition of the temperature change value ΔTts. Based on the actual monitored longitudinal displacement change value ΔXts and the calculated longitudinal displacement value ΔDts obtained by simulation calculation, we can calculate the correction coefficient K1. The calculation formula of the correction coefficient K1 is: K1=ΔXts / ΔDts. This correction coefficient reflects the difference between the actual displacement and the theoretical 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 value Dsh of the longitudinal displacement generated by 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, in S200, the following steps are included:

[0050] S201: Calculate the longitudinal displacement Dx of the new bridge bearing 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 life correction coefficient K2.

[0051] In this embodiment, in order 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 bearing age correction coefficient K2. Here, the bearing age correction coefficient K2 is a coefficient used to consider the influence of the bearing age on the displacement. In this way, we can comprehensively consider the influence of the theoretical value, the actual value and the bearing age, so as to calculate a more accurate longitudinal displacement of the new bridge bearing.

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

[0053] Furthermore, in one embodiment, in S200, the following steps are included:

[0054] S201: Calculate the longitudinal displacement Dx of the new bridge bearing 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 permanent deformation Dsun of the bearing to be replaced.

[0055] In this embodiment, in order 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 bearing to be replaced, and the permanent deformation Dsun of the bearing to be replaced. In this way, we can comprehensively consider the influence of the theoretical value, the actual value and the bearing damage, so as to calculate 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, in S100, the following steps are included:

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

[0059] In this embodiment, a finite element model of the bridge structure is established according to the actual geometric shape of the bridge. The various parts of the bridge are defined in the model, including the beam body, bearings, piers, etc. The correct material properties, such as elastic modulus, Poisson's ratio, density, etc., are specified for each part in the model. The boundary conditions of the bridge are defined, such as fixed constraints of piers, sliding constraints of bearings, etc. All relevant loads from the completion of the bridge to the present are applied. The model is calculated using finite element calculation software to obtain 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 from the completion of the bridge to the present. 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 from the completion of the bridge to the present. This theoretical value will be used for the subsequent calculation of the longitudinal displacement of the new bridge bearing.

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

[0061] S101-1: All relevant loads from the completion of the bridge to the present include external and internal loads that have affected the bridge structure from the completion of the bridge to the present.

[0062] In this embodiment, since the completion of the bridge, all loads that have an impact on the bridge structure mainly include three categories: permanent loads, variable loads and accidental loads. Permanent loads: including structural deadweight, prestress, soil weight and soil side pressure, etc. These loads remain basically unchanged during the design service life of the bridge and have a direct impact on the safety and durability of the bridge structure. Variable loads: such as vehicle loads, crowd loads, wind force, temperature influence, bearing friction, etc. These loads may change during the design service life of the bridge and have a dynamic impact on the bridge structure. Accidental loads: such as earthquake forces, impact forces of ships or drifting objects, these loads may not appear during the design service life of the bridge, but once they appear, they may have a greater impact on the bridge structure.

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

[0064] Step 1: Before replacing the bearing, measure the actual longitudinal displacement Dsp between the center of the upper and lower bearing plates of the bridge bearing to be replaced on site;

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

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

[0067] Step 4: Establish a finite element calculation model of the bridge structure based on the design drawings and data;

[0068] (1) Calculate the theoretical value Dsh of the longitudinal displacement of the bearing to be replaced due to the shrinkage creep effect from the completion of the bridge to the present time;

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

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

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

[0072] (2) Determine the bearing life correction coefficient K2 based on the operation time of the bridge structure from completion. If the operation time is greater than 20 years, K2 = 1.0; if the operation time is less than or equal to 10 years, K2 = 1.3. Intermediate operation times can be linearly interpolated;

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

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

[0075] Wherein, Dsun takes a positive value when the deformation directions are the same as Dsp, and takes a negative value when the deformation directions are opposite to Dsun.

[0076] After calculating the longitudinal displacement Dx of the new bearing, design a new bearing that meets the longitudinal displacement Dx, and replace the old bearing. The replacement construction method is as follows:

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

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

[0079] Step 3: Use a jack to lift the support. After reaching the lifting displacement, lock the temporary support.

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

[0081] Step 5: Install the new support. First, align the lower seat plate of the new support with the marked center line of the lower seat plate of the original support, and install the lower seat plate connecting components to meet the anchoring requirements;

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

[0083] Step 7: Use a jack to drop the beam and restore it to the original design elevation of the support to ensure that the support is evenly stressed and remove the temporary support;

[0084] Step 8: Install the connecting components of the new bearing upper seat plate to meet the anchoring requirements and release the longitudinal constraints of the bearing;

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