Description

Technical Field

[0001] This invention relates to the field of arch rib installation technology, and specifically to a calculation method, apparatus, computer equipment, and storage medium for arch rib segment installation. Background Technology

[0002] The cable-stayed bridge method is the main construction method for long-span arch bridges. During construction, the arch bridge is divided into several arch rib segments, which are suspended and hooked together one by one until the arch ribs are closed. This construction method requires tensioning the cable to adjust the installation position of each arch rib segment in order to achieve precise splicing.

[0003] Currently, the common practice is to fix a monitoring point at an appropriate location on each arch rib segment and directly control the segment installation position by comparing the actual installation elevation of each monitoring point with the theoretical control elevation. However, in actual construction, there are often problems with segments being made too long or too short. Especially during the tensioning of the cable, the arch rib segment will be deformed by stress, and the actual position of the fixed monitoring point will also change. This results in the elevation of the installed arch rib segment being too high or too low, reducing the installation accuracy of the arch rib segment. Summary of the Invention

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] Figure 1 The diagram shown is a flowchart illustrating a calculation method for arch rib segment installation provided by an embodiment of the present invention; as follows: Figure 1 As shown, the calculation method for the installation of the arch rib segment specifically includes the following steps:

[0029] Step S101: Before installing the arch rib segment, establish a rectangular coordinate system based on the manufacturing line of the arch rib. The origin of the coordinate system is set at the center of the arch foot section. Based on the manufacturing line coordinates of each node on the arch rib segment in the rectangular coordinate system, establish the corresponding finite element model.

[0030] It should be noted that the arch rib segments are not under stress before installation, so the arch ribs in this state are used to manufacture the linear arch ribs; during the installation of the arch rib segments, the arch rib segments will undergo different degrees of deformation under the combined action of their own weight and the tension of the ties, so the arch ribs in this state are used to manufacture the deformed arch ribs.

[0031] In this embodiment, before the arch rib segment is installed, the manufactured linear arch rib segment is divided into multiple nodes, and a rectangular coordinate system is established with the center of the arch foot section as the origin. Figure 2 The image shows the first arch rib segment, which is divided into 11 nodes. Nodes 0 and 10 are located at the two ends of the arch rib segment, respectively. Node 0 is also the center of the arch foot section. Therefore, the coordinates of each node in the manufacturing linear rectangular coordinate system can be obtained, which is called the manufacturing linear coordinate system, also known as the station and elevation.

[0032] It should be noted that, Figure 2This includes the arch rib segment 100 (shown as a solid line), the arch rib segment 200 (shown as a dashed line), the arch rib axis 300, the tensioning cable 400, the pier 500, and the anchor cable 600. To better illustrate the correspondence between the coordinates of the manufacturing alignment, measured elevation, measured station number, theoretical control elevation, and theoretical control station number, this embodiment compares the arch rib segment 100 and the deformed arch rib segment 200 within the same coordinate system. However, the actual positional relationship between the manufactured arch rib segment and the deformed arch rib segment is not... Figure 2 The relationship between them, therefore Figure 2 It cannot explain the actual positional relationship between the two; it is only used to illustrate the position of the deformed arch rib segment during the current installation, and its theoretical comparison with the position before deformation. However, from... Figure 2 It can be clearly stated that both are coordinate systems established with the same node as the origin.

[0033] Step S102: During the installation of the arch rib segment, any point on the deformed arch rib segment is taken as the target monitoring point, and the actual station number and actual elevation of the target monitoring point are measured.

[0034] In this embodiment, the measured station number is the measured horizontal distance from the target monitoring point to the target node, the measured elevation is the measured vertical distance from the target monitoring point to the target node, and the target node is the center of the arch foot section, which is the origin of the rectangular coordinate system.

[0035] It should be noted that, as Figure 2 As shown, a target monitoring point A is set on the arch axis 300 of the deformed arch rib. Any point on the deformed arch rib can also be used as the target monitoring point. The horizontal and vertical distances from point A to point 0 are measured by a measuring instrument and used as the actual station number and actual elevation of point A, respectively.

[0036] Step S103: Based on the measured station number and measured elevation of the target monitoring point, calculate the target manufacturing line coordinates corresponding to the target monitoring point on the arch rib manufacturing line.

[0037] In this embodiment, as Figure 3 As shown, step S103 specifically includes the following steps:

[0038] Step S201: Obtain the theoretical displacement of each node on the arch rib manufacturing line based on the finite element model of the arch rib segment.

[0039] Wherein, the theoretical displacement is the simulated change value from the position on the manufactured linear arch rib segment to the position on the deformed arch rib segment;

[0040] Step S202: Calculate the theoretical deformation length from each node to the target node based on the manufacturing linear coordinates of each node and the theoretical displacement of each node.

[0041] Step S203: Calculate the target length from the target monitoring point to the target node based on the measured station number and the measured elevation;

[0042] Step S204: The theoretical deformation length of each node is compared with the target length in a loop to obtain the first adjacent node and the second adjacent node adjacent to the target monitoring point.

[0043] Step S205: Calculate the manufacturing line coordinates of the target monitoring point on the arch rib segment of the manufacturing line based on the manufacturing line coordinates of the first adjacent node and the second adjacent node.

[0044] It should be noted that the finite element model in this implementation is a model built using Midas / Civil finite element software, wherein the finite element model includes the theoretical displacement of each node in each arch rib segment ( ), Let i represent the horizontal and vertical displacements of the i-th node, i = 1, 2, 3, ...; where the 0th node is located at the arch foot of the arch rib, and its horizontal and vertical displacements are both 0, that is, this node has no displacement.

[0045] In this embodiment, combined with Figure 2 and 4 It can be seen that, based on the manufacturing linear coordinates of each node in the manufacturing linear rectangular coordinate system and the theoretical displacement of each node, the formula for calculating the theoretical deformation length from each node to the target node is as follows:

[0046]

[0047] in, Indicates the first The theoretical deformation length from node i to the target node, i=1,2,3,…; , () represents the manufacturing linear coordinates of the i-th node. Let these represent the horizontal and vertical displacements of the i-th node, respectively. , ) represents the manufacturing linear coordinates of the target node; the theoretical deformation length is the straight-line distance from each node on the deformed arch rib to the target node.

[0048] In this embodiment, as Figure 4 As shown, based on the measured station number and the measured elevation, the formula for calculating the target length from the target monitoring point to the target node is as follows:

[0049]

[0050] in, The actual station number of the target monitoring point. The measured elevation of the target monitoring point.

[0051] In this embodiment, the theoretical deformation length of each node is cyclically compared with the target length. When the target monitoring point A is determined to be between the j-th node and the (j+1)-th node, the j-th node is designated as the first adjacent node of the target monitoring point, and the (j+1)-th node is designated as the second adjacent node of the target monitoring point. This represents the theoretical deformation length of the j-th node. This represents the theoretical deformation length of the (j+1)th node. Indicates the target length. .

[0052] In this embodiment, the formula for calculating the manufacturing line coordinates of the target monitoring point on the arch rib segment of the manufacturing line, based on the manufacturing line coordinates of the first adjacent node and the second adjacent node, is as follows:

[0053]

[0054] in, These represent the horizontal and vertical displacements of the j-th node, respectively. These represent the horizontal and vertical displacements of the (j+1)th node, respectively. , () represents the manufacturing linear coordinates of the target monitoring point.

[0055] In this embodiment, the manufacturing linear coordinates of the target monitoring point can also be the theoretical station number and theoretical elevation of the target monitoring point.

[0056] Step S104: Calculate the theoretical control station number and theoretical control elevation of the target monitoring point based on the target manufacturing linear coordinates corresponding to the target monitoring point.

[0057] In this embodiment, the theoretical control station number and theoretical control elevation of the target monitoring point are calculated based on the target manufacturing alignment coordinates corresponding to the target monitoring point. This includes: calculating the target theoretical displacement corresponding to the target monitoring point based on the manufacturing alignment coordinates of the target monitoring point, the manufacturing alignment coordinates of the first adjacent node, and the manufacturing alignment coordinates of the second adjacent node; and obtaining the theoretical control station number and theoretical control elevation of the target monitoring point based on the manufacturing alignment coordinates and the target theoretical displacement.

[0058] It should be noted that the theoretical displacement of the target monitoring point A can be obtained through interpolation. The calculation formula is as follows:

[0059]

[0060] in, These represent the horizontal and vertical theoretical displacements of the target monitoring point, respectively. The horizontal and vertical theoretical displacements of the target monitoring point can also be used as the displacement results of the target monitoring point before and after the deformation of the arch rib segment.

[0061] In this embodiment, based on the manufacturing linear coordinates of the target monitoring point and the theoretical displacement of the target, the calculation formulas for the theoretical control station number and theoretical control elevation of the target monitoring point are as follows:

[0062]

[0063] in, Indicates the theoretical control station number. This indicates the theoretical control elevation.

[0064] Step S105: Based on the first error between the theoretical control station number and the measured station number of the target monitoring point, and the second error between the theoretical control elevation and the measured elevation of the target monitoring point, control the installation position of the current arch rib segment.

[0065] It should be noted that during the installation of the arch rib segments, tensioning is used... Figure 2 The 400mm tension cable is used to adjust the installation position of the arch rib segment, and the measured station number and measured elevation of the target monitoring point will change each time the tension cable is tensioned. and When the time is right, it indicates that the arch rib segment has been installed in place, and the arch rib segment should be kept in its current installation position; conversely, when the time is wrong, it indicates that the arch rib segment has not yet been installed in place, and the tensioning cables should continue to adjust the installation position of the arch rib segment until the above conditions are met; among which, This represents the first error between the theoretical control station number and the measured station number of the target monitoring point. This represents the second error between the theoretical control elevation and the measured elevation of the target monitoring point. Indicates the first error threshold. This represents the second error threshold.

[0066] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0067] 1. This invention selects an arbitrary point on the deformed arch rib segment as a target monitoring point, and then calculates the theoretical control station and theoretical control elevation of the arch rib segment before deformation by combining the measured station number and measured elevation of the target monitoring point with the displacement results of the arch rib segment before and after deformation. Finally, it determines whether the arch rib segment is installed correctly by using the first error between the theoretical control station number and the measured station number of the target monitoring point, and the second error between the theoretical control elevation and the measured elevation of the target monitoring point. Therefore, this invention, by fully considering the arch rib deformation displacement and arch rib manufacturing error, transforms the traditional single elevation change parameter into construction control based on two parameters: station number and elevation. This makes the measurement and calculation results more accurate and effectively improves the installation accuracy of the arch rib segment.

[0068] 2. The target monitoring points in this invention do not need to be fixed in advance. They can be set randomly according to needs and convenience, avoiding problems such as fixed monitoring points being blocked, which may cause measurement failure.

The measured vertical distance is used to determine the target node, which is the center of the arch foot section. A manufacturing line coordinate calculation module is used to calculate the target manufacturing line coordinates of the target monitoring point on the arch rib manufacturing line based on the measured station number and measured elevation of the target monitoring point. A theoretical control station number and elevation calculation module is used to calculate the target manufacturing line coordinates of the target monitoring point on the arch rib manufacturing line based on the measured station number and measured elevation of the target monitoring point. A comparison control module is used to control the installation position of the current arch rib segment based on the first error between the theoretical control station number and the measured station number of the target monitoring point, and the second error between the theoretical control elevation and the measured elevation of the target monitoring point.

During the installation of the arch rib segment, any point on the deformed arch rib segment is used as a target monitoring point, and the measured station number and measured elevation of the target monitoring point are measured. The measured station number is the target monitoring point's... The measured horizontal distance from the measuring point to the target node, and the measured elevation, are the measured vertical distances from the target monitoring point to the target node, where the target node is the center of the arch foot section.
