Description

Technical Field

[0001] The present invention relates to the technical field of bridge construction, and in particular to a method for correcting positioning coordinates of tower-beam synchronous construction under a cable force equilibrium state. Background Art

[0002] During the synchronization of towers, beams, and cables, the tower columns begin to bear the loads of the stay cables before the main tower is capped. This causes deviations in the actual shape, internal forces, and stress state of the tower columns from the theoretical design state (i.e., when constructed according to the conventional tower-first, beam-later construction process). Therefore, with the advancement of bridge construction technology and the improvement of bridge linearity and structural stress monitoring methods, identifying these deviations through advance calculation and analysis, and proposing targeted control and adjustment measures, has become a very important technology in the synchronization of towers, beams, and cables. This, combined with detailed scheduling and subdivision of steps, allows for the rational arrangement of overlapping processes occurring at the same time during the synchronization process.

[0003] During the simultaneous tower-beam construction phase, the tower's alignment was subject to a variety of complex factors, including additional loads caused by factors such as sunlight, air temperature, wind, and steel beam deformation; asymmetric wind loads acting on the main beam; asymmetric loads caused by construction; loads from the cable stays; shrinkage, creep, and compression deformation of the tower's concrete; and other factors. These factors could cause the tower to twist or deform, resulting in changes in its positioning coordinates. Despite appropriate measures such as alignment control and cable tension adjustment during construction, the influence of external conditions on the design coordinates persisted, necessitating corrections to the cable anchor positioning coordinates of the cable-stayed bridge.

[0004] At present, the correction of the cable anchor positioning coordinates of cable-stayed bridges is mostly achieved through tower prism monitoring. A total station is set up at the construction density point of the side pier or auxiliary pier top. Before positioning, all tower prisms are observed, and the observed values of the prisms on each layer are compared with the initial values. A mathematical model is established using a quadratic parabola to calculate the correction value of the cable anchor positioning coordinates. However, the above scheme is only applicable to the synchronous construction of towers and beams based on the bridge line shape, that is, the cable tension on the side span side of the tower is greater than that on the mid-span side at each layer. It is not applicable to the synchronous construction of towers and beams with balanced cable tension on both sides of the tower. The synchronous construction of towers and beams with balanced cable tension on both sides of the tower is carried out through strict construction organization and cable tension monitoring. The external load construction error is small, and the deformation of the tower caused is also small. The direction of tower shape change (side span side, mid-span side) is random, and the deformation of the tower shape of the lower crossbeam and the tower above it changes approximately linearly.

[0005] Tower column positioning often relies on external control methods, where a total station is set up at a known control point on the ground or on the top of a side pier. Other control points are then viewed from behind, and measurements are performed using corrected positioning coordinates. However, tower column deformation persists during the positioning process. Changes in external conditions require real-time monitoring using the tower column prism, requiring multiple positioning coordinate corrections. This results in low construction efficiency and increased costs.

[0006] In view of this, there is an urgent need to improve the correction method of positioning coordinates in the synchronous construction of cable-stayed tower beams in the existing technology, so as to improve the accuracy of the positioning coordinate correction results and the tower column positioning efficiency and reduce construction costs. Summary of the Invention

[0007] In response to the above-mentioned defects, the purpose of the present invention is to provide a method for correcting the positioning coordinates of the tower-beam synchronous construction under the cable tension equilibrium state, so as to solve the influence of external factors on the positioning coordinates and solve the influence of the tower column deformation on the positioning coordinates during the positioning process of the cable-stayed bridge.

[0012] Determine a time period that satisfies both the first and second conditions as a positioning time period, monitor tower column deformation during the positioning time period, and determine a correction amount for the positioning coordinates based on a linear relationship between the change amount and the construction height;

[0019] The bridge axis coordinate system is established with the center of the cable-stayed bridge tower pier as the coordinate origin and the direction of increasing mileage as the positive direction of the X-axis.

[0020] In the above technical solution, preferably, determining the time period that satisfies the first condition comprises the following steps:

[0021] Arrange observation prisms on the lower crossbeam of the tower column and the constructed tower column above it;

[0022] Before entering the tower-beam synchronous construction, the tower column prism is continuously observed; wherein the observation frequency of the tower column prism is: on the first day of observation, observation is once every 2 hours; on the second day, observation is once every 4 hours;

[0023] Based on the observation data, the first condition required for positioning coordinate correction is determined, that is, the time period when the natural environment has the least impact on the tower column posture and is relatively stable.

[0024] In the above technical solution, preferably, determining the correction amount of the positioning coordinates includes the following steps:

[0025] During the time period, the tower column prism is observed, and the difference between the prism observation value and the initial value is determined as the change. A linear relationship between the change and the construction height is established, and the positioning coordinates are corrected.

[0026] In the above technical solution, preferably, the determining of the correction amount of the positioning coordinates further includes the following steps:

[0027] The initial value of the newly buried prism is calculated based on the change in the tower column prism that has been constructed and the height between the tower column prisms.

[0032] Set up the total station at the encrypted point of the tower column and set up the station with the shore or other known construction control points as the back sight point.

[0033] It can be seen from the above technical solution that the method for correcting the positioning coordinates of the tower-beam synchronous construction under the cable force equilibrium state provided by the present invention has the following advantages:

[0034] Firstly, by observing the deformation of the tower column before and during the synchronous construction of the tower column, the time period that simultaneously meets the first and second conditions is determined as the positioning time period, so that the tower deformation detection is carried out under the state of cable force equilibrium, thereby avoiding the influence of the tower column deformation caused by external factors on the accuracy of the positioning coordinate correction result; when performing coordinate correction, a linear relationship between the change of the observation prism and the construction height is established, and the change model of the synchronous positioning coordinates of the cable-stayed bridge tower and beam under the cable force equilibrium state is trimmed to make the change law of the positioning coordinates consistent with the change law of the positioning coordinates in actual construction, thereby improving the accuracy of the coordinate correction value and making it suitable for the correction of the synchronous positioning coordinates of the cable-stayed bridge tower and beam under the cable force equilibrium state.

[0035] Secondly, by setting tower column densification points on the section to be constructed, and measuring the elevation and plane coordinates of the tower column densification points at the same time when conducting tower column prism monitoring, a total station is set up at the tower column densification points to set up the station, and the tower column is positioned so that the positioning changes of the total station during the positioning process are consistent with the tower column deformation, thereby eliminating the influence of the tower column deformation on the tower column positioning, and there is no need to correct the positioning coordinates multiple times during the positioning process, which greatly reduces the workload of tower column positioning and improves the synchronous construction efficiency of the cable-stayed tower and beam.

[0041] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] The implementation principle of the present invention is:

[0043] By observing the deformation of existing tower columns before construction and rigorously organizing and monitoring cable tension during the simultaneous tower-beam construction phase, we identified a time period that simultaneously minimizes column deformation, maintains a relatively stable posture, and minimizes the linear impact of external loads on the column. This time period serves as the positioning period. During this positioning period, column deformation is measured, and a linear model is established between the change in column deformation and construction height to correct coordinates, ensuring that the corrected coordinates conform to the tower column deformation pattern.

[0044] By measuring the elevation and plane coordinates of the tower column densification points simultaneously when monitoring the deformation of the tower column, the deformation of the tower column densification points is kept consistent with the deformation of the tower column, and a total station is set up at the tower column densification points, and the tower column positioning measurement is carried out using the three-dimensional coordinate method, so that the tower column deformation can be used to correct the tower column positioning measurement results during tower positioning.

[0045] The solution provided by the present invention can complete the correction of the positioning coordinates of the synchronous construction of the tower and beam of the cable-stayed bridge under the cable tension equilibrium state, greatly improving the accuracy of the tower column positioning coordinate correction results and the precision of the tower column positioning. During the correction and positioning of the tower column coordinates, there is no need to perform multiple corrections of the positioning coordinates, which greatly improves construction efficiency and reduces construction costs.

[0046] Specifically, the method for correcting the positioning coordinates of the tower-beam synchronous construction under the cable force equilibrium state provided by the present invention includes the following steps:

[0047] Optimize the construction control network before the construction of cable-stayed bridge towers;

[0048] Observe the deformation of the constructed tower column and determine the time period that meets the first condition; wherein the first condition is that the tower column has the smallest deformation and the tower column is stable under natural conditions;

[0049] During the simultaneous tower and beam construction phase, through strict construction organization and cable force monitoring, the time period in which the second condition is met is determined; wherein the second condition is that the external load conditions have minimal impact on the tower column line shape and the tower column posture is stable;

[0050] Determine a time period that satisfies both the first and second conditions as a positioning time period, monitor tower column deformation during the positioning time period, and determine a correction amount for the positioning coordinates based on a linear relationship between the change amount and the construction height;

[0051] The elevation and plane coordinates of the tower column densification points are measured synchronously with the tower column deformation monitoring; a total station is set up at the tower column densification points, and the tower column positioning measurement is carried out using the three-dimensional coordinate method.

[0056] Specific embodiment 1.

[0057] like Figure 1 As shown, the method for correcting the positioning coordinates of the tower-beam synchronous construction under the cable force equilibrium state provided by the present invention includes the following steps:

[0058] S1. Optimize the construction control network before the construction of the cable-stayed bridge tower column;

[0059] S2. Observe the deformation of the constructed tower column to determine a time period that satisfies a first condition, wherein the first condition is that the tower column has minimal deformation and a stable posture under natural conditions;

[0060] S3. During the tower-beam simultaneous construction phase, through strict construction organization and cable force monitoring, determine the time period that meets the second condition; wherein the second condition is that the external load conditions have minimal impact on the tower column line shape and the tower column posture is stable;

[0061] S4. Determine a time period that satisfies both the first condition and the second condition as a positioning time period, monitor tower column deformation during the positioning time period, and determine a correction amount for the positioning coordinates based on a linear relationship between the change amount and the construction height;

[0062] S5. Simultaneously with the tower column deformation monitoring, the elevation and plane coordinates of the tower column densification points are measured; a total station is set up at the tower column densification points, and the tower column positioning measurement is carried out using the three-dimensional coordinate method.

[0063] Specific embodiment 2.

[0064] This embodiment is a further optimization of the bridge construction control network optimization in specific embodiment 1.

[0065] like Figure 2 As shown in Figure 1, the optimization of the bridge construction control network includes the following steps:

[0066] S11. Based on the primary control network 1 of the line, re-measure the bridge construction control network 2;

[0067] S12. On the basis that the re-survey of the bridge construction control network 2 meets the requirements of relevant specifications, the construction encrypted control point measurement is carried out.

[0068] The measurement of construction density control points is used for the later deformation monitoring of tower columns and the three-dimensional coordinate measurement of tower column density control points. The construction density control points can be arranged on the top of the adjacent main pier 6, side pier 3 or auxiliary pier 4, and a forced centering device can be set on the construction density control points.

[0069] S13. Establish a bridge axis coordinate system with the center of the fifth pier of the cable-stayed bridge tower as the coordinate origin and the direction of increasing mileage as the positive direction of the X-axis.

[0070] Specific embodiment 3.

[0071] like Figure 3 As shown, this embodiment is a further optimization of the first condition required for determining positioning coordinate correction described in Specific Embodiment 1, and includes the following steps:

[0072] S21, laying out observation prisms 8 on the lower crossbeam of the tower column and the already constructed tower column above it;

[0073] S22, total station 7 is set up at the construction encryption point on the top of side pier 3, and the station is set up at the bridge construction control point 2;

[0074] S23. Before entering the tower-beam synchronous construction, the tower column prism 8 is continuously observed. On the first day of observation, the observation is conducted once every 2 hours; on the second day, the observation is conducted once every 4 hours;

[0075] S24. Determine a time period that satisfies a first condition based on the observation data. The first condition is a time period in which the natural environment has the least impact on the tower column posture and is relatively stable.

[0076] Specific embodiment 4.

[0077] This embodiment is a further optimization of the corrected positioning coordinates in specific embodiment 1.

[0078] Correcting the positioning coordinates includes the following steps:

[0079] S41. Within the positioning time window, observe the tower column prism 8 through the total station, take the difference between the prism observation value and the initial value as the change of the tower column prism 8, establish a linear relationship between the change and the construction height, and correct the positioning coordinates.

[0080] In the above process, the linear change of the tower column caused by the construction error has directional uncertainty, and the change amount changes linearly with the construction height. By establishing a linear relationship between the change amount and the construction height, the corrected positioning coordinates can meet the changes in the tower-beam positioning coordinates during the synchronous construction of the cable-stayed bridge tower and beam under the state of cable force equilibrium.

[0081] S42. Calculate the initial value of the newly buried prism based on the change in the tower column prisms that have been constructed and the height between the tower column prisms.

[0082] The initial value of the newly buried prism can be calculated based on the linear relationship between the change in the existing prism and the height between the prisms. The specific structure is shown in the following table:

[0085] Specific embodiment 5.

[0086] like Figure 4 As shown, this embodiment is a further optimization of the tower column density point measurement and tower column positioning measurement in specific embodiment 1.

[0087] S51. Arrange the reinforcement points of the rigid frame or installation piles in the section of the tower column to be constructed, and use a forced centering device;

[0088] S52, synchronously measuring the elevation and plane coordinates of tower column densification points with tower column deformation monitoring;

[0089] Among them, the plane coordinate measurement of the tower column encryption point 9 is based on the tower column height and the distribution of construction control points, using the method of edge intersection, free station setting or vertical instrument projection;

[0090] The elevation measurement of tower column encryption point 9 adopts the method of precise triangulation height measurement or zenith distance measurement of total station according to the tower column height and the distribution of construction control points.

[0091] S53, the total station 7 is set up at the tower column encryption point 9, and the shore or other known bridge construction control point 2 is used as the back sight point to set up the station, and the three-dimensional coordinates are positioned and measured for the cable guide tube 10.

[0092] The coordinates of the tower column encryption point 9 are measured synchronously with the deformation of the tower column within the positioning time window. Therefore, during the positioning process, the coordinate changes of the tower column encryption point 9 can be regarded as basically consistent with the deformation of the tower column, and there is no need to correct the positioning coordinates again.

[0093] In summary, this method optimizes the construction control network before cable-stayed bridge tower construction. Deformation observations of the constructed towers determine the first condition for correcting positioning coordinates: minimum tower deformation and relatively stable posture. During the simultaneous tower-beam construction phase, rigorous construction organization and cable tension monitoring provide the second condition for correcting positioning coordinates: minimal impact of external loads on the tower's linear shape. When both conditions are met, tower deformation monitoring is used to determine the correction amount for the design coordinates, and simultaneous elevation and plane coordinate measurements of the tower's infill points are performed. Total stations are then set up at the tower's infill points, using the three-dimensional coordinate method for tower positioning. During the period when both the first and second conditions are met, the design coordinates are corrected using a linear relationship through tower posture measurement. This reduces the number of prism observations, simplifies calculations, and reduces workload. It also addresses the secondary effects of the external environment on the positioning coordinates during cable-stayed bridge positioning, avoids the time required to re-correct the positioning coordinates due to repeated tower posture monitoring, and improves measurement efficiency.

[0094] Finally, it should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the conditions for the implementation of this application.
