Obviously, the described embodiments are only some embodiments of this application, and 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.

[0023] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1 As shown in the figure, this application provides a calculation and analysis method for landscape arch bridges. The bridge calculation model method includes the following steps: S110. Identify and construct the bridge surface model of the landscape arch bridge, and confirm the long side parameters and short side parameters of the bridge surface model.

[0025] S120. Obtain the input parameters and construct the bridge plan model and stiffening plate model of the landscape arch bridge based on the long side parameter, short side parameter and input parameters.

[0026] S130. Calculate the support pile parameters of the landscape arch bridge based on the bridge plan model and input parameters, and construct the support pile model.

[0027] S140. Based on the bridge surface model, bridge plan model, stiffening plate model, and support pile model, the bridge calculation model is confirmed, and the output parameters are calculated through the bridge calculation model.

[0028] S150. Adjust the input parameters based on the output parameters and update the bridge calculation model until the output parameters meet the preset conditions.

[0029] This application provides a calculation and analysis method for landscape arch bridges. It obtains a bridge planar model and a stiffening plate model by combining a bridge surface model with input parameters, and then obtains a support pile model and a bridge calculation model for calculation and output. In use, users only need to input the required parameters sequentially, making it simple and convenient to use and effectively improving the efficiency of calculation and analysis. After obtaining the calculation model, the output parameters can be used to verify, update, and adjust the bridge calculation model, effectively ensuring the accuracy of the analysis and calculation process.

[0030] like Figures 2-3 As shown, the process of confirming the long side parameter and the short side parameter in step S110 is as follows: The upper curved surface of the bridge is identified, and its first long side and first short side are confirmed. The long side parameter includes the three-dimensional spatial data of the first long side, and the short side parameter includes the three-dimensional spatial data of the first short side. The three-dimensional spatial data includes at least the three-dimensional coordinates of the upper endpoints of the long and short sides. In the three-dimensional coordinate system of this application embodiment, the length direction of the bridge is used as the X-axis, the width direction of the bridge is used as the Y-axis, and the height direction of the bridge is used as the Z-axis.

[0031] After identifying the upper surface, it is necessary to combine the upper surface to obtain the lower surface of the bridge. The input parameters include the bridge thickness. The above step S120 specifically includes: S121, Input the bridge thickness.

[0032] S122. Move the upper surface along the Z-axis of the three-dimensional coordinate system to obtain the lower surface of the bridge. Confirm the second long side and the second short side of the lower surface. The long side parameter also includes the three-dimensional spatial data of the second long side, and the short side parameter includes the three-dimensional spatial data of the second short side.

[0033] S123. Sweep the first long side towards the second long side to obtain the side plane of the bridge, and sweep the first short side towards the second short side to obtain the end plane of the bridge. The bridge planar model includes two end planes and two side planes.

[0034] like Figure 3 As shown, the lower surface is obtained by copying the upper surface by moving it along the Z-axis. The first long side includes long side a1 and long side a2, and the second long side includes long side b1 and long side b2. The first and second long sides are symmetrically arranged, and their projections on the horizontal plane coincide. The first and second short sides are also symmetrically arranged, and their projections on the horizontal plane coincide. The side planes of the bridge include plane A1 and plane A2, and the end planes of the bridge include plane A3 and plane A4.

[0035] For example, the input parameters also include a first spacing distance of the longitudinal stiffening plates and a second spacing distance of the transverse stiffening plates. Specifically, step S120 further includes: S124. Input the first interval distance and the second interval distance.

[0036] S125. Determine the length of the short side of the first short side and the second short side based on the endpoint of the first short side or the second short side, and determine the length of the long side of the first long side and the second long side based on the endpoint of the first long side or the second long side.

[0037] S126. Calculate the number of longitudinal stiffening plates based on the length of the short side and the first interval distance, and calculate the number of transverse stiffening plates based on the length of the long side and the second interval distance.

[0038] S127. Based on the number of longitudinal stiffening plates, the side plane is copied at intervals along the direction of the short side length to obtain the corresponding number of longitudinal stiffening plate planes. Based on the number of transverse stiffening plates, the end plane is copied at intervals along the direction of the long side to obtain the corresponding number of transverse stiffening plate planes.

[0039] S128. Assign thicknesses to the transverse stiffening plate plane and the longitudinal stiffening plate plane sections to obtain the stiffening plate model.

[0040] As can be seen from the above steps, the transverse stiffening plate and the end plane correspond to each other, and the longitudinal stiffening plate and the side plane correspond to each other. By copying and translating the end plane and the side plane, a uniform and evenly spaced stiffening plate plane can be obtained. The obtained stiffening plate plane is located inside the arch bridge.

[0041] For example, the end plane and side plane can be moved along the Z-axis by the thickness of the bridge, and then translated and copied, so that the stiffening plate plane is located below the arch bridge.

[0042] The input parameters also include the geometric and material parameters of the support pile. Specifically, step S130 above includes: S131. Obtain the geometric parameters of the support piles, including the number of piles, pile spacing, pile length, pile diameter, and number of pile segments.

[0043] S132. Confirm the center coordinates of the end plane. The Z-axis coordinate of the pile apex of the support pile is the same as the center coordinate.

[0044] S133. Determine the coordinates of the pile apex of the support pile based on geometric parameters and center coordinates.

[0045] S134. Based on geometric parameters and the coordinates of the pile apex, determine the coordinates of the pile bottom point of the support pile.

[0046] S135. Based on the coordinates of the pile apex, the coordinates of the pile bottom, and the geometric parameters, determine the coordinates of the midpoint of each midpoint on the support pile.

[0047] S136. Obtain the material parameters of the support piles, and construct the support pile model for each support pile by combining the geometric parameters, pile vertex coordinates, pile bottom coordinates, and midpoint coordinates.

[0048] The material parameters include material grade, soil thickness, and horizontal resistance coefficient. By obtaining these material parameters, the three-dimensional coordinates of each node are confirmed, including the pile apex, pile bottom, and midpoint.

[0049] The soil spring stiffness of each node is calculated based on material parameters, the three-dimensional coordinates of the nodes, and geometric parameters, and is used as the elastic constraint element of the nodes. The soil spring stiffness calculation method is as follows: (1) Among them, L z V represents the pile length. z D represents the number of pile segments. z Indicates the pile diameter, Z a1,1 The vertical depth of a node is represented by m. a1,1 This represents the horizontal resistance coefficient of the node.

[0050] The pile calculation elements for the support pile are determined based on the geometric parameters and the three-dimensional coordinates of the nodes. The pile constraint elements for the support pile are determined based on the three-dimensional coordinates of the nodes, the elastic constraint elements, and the material grade. The support pile model is obtained by combining the pile calculation elements and the pile constraint elements.

[0051] The pile calculation element represents the geometric data of all the aforementioned nodes, clearly defining the shape, size, and positional relationships of each support pile. The pile constraint element represents attribute data, including the calculated soil spring stiffness, soil thickness, and material grade. These constraints are applied to the support piles through material properties and stress analysis. Using both the pile calculation element and the pile constraint element, a complete support pile model can be obtained for subsequent calculations.

[0052] In some embodiments, the above-mentioned nodes also include each connection point in the bridge surface model, bridge planar model, and stiffening plate model mentioned above. Each connection point can also be constrained in the above manner so that the final bridge calculation model satisfies the material constraint conditions.

[0053] For example, when performing calculations using a bridge computational model, the output parameters obtained include maximum stress, maximum vertical deformation, and maximum horizontal displacement at the pile top. Preset conditions include at least one of the following: the output parameter is not greater than a preset stress value, the maximum vertical deformation does not exceed a preset deformation value, and the maximum horizontal displacement at the pile top does not exceed a preset displacement. The output parameters are primarily used to verify the accuracy of the model. If one or more output parameters do not meet the conditions, it indicates a deviation in the input parameters mentioned above, resulting in an inaccurate model. The input parameters need to be readjusted, and the calculation process repeated until the final output parameters meet the preset conditions.

[0054] The process of detecting and providing feedback through output parameters can continuously optimize the final bridge calculation model, making the calculation and analysis process more accurate and meeting the needs of actual use.

[0055] The following is combined Figure 2 and Figure 3 The method steps in the embodiments of this application are described in detail below: 1. Identify the upper curved surface R1 in the landscape arch bridge and obtain the first long side a1, a2 and the first short side a3, a4 of the surface.

Sweep from curve a1 to curve b1 to form bridge side plane A1, sweep from curve a2 to curve b2 to form bridge side plane A2, sweep from curve a3 to curve b3 to form bridge end plane A3, and sweep from curve a4 to curve b4 to form bridge end plane A4.

That is, the number of longitudinal stiffening plates is determined by the length of the first short side and the first interval distance. When calculating the number of longitudinal stiffening plates, the rounding method is used. For example, if the calculation result is 3.3, then the number is 4.
