Description
Technical Field
[0001] This invention relates to the field of road and bridge design technology, and in particular to a method and related apparatus for determining bridge design schemes. Background Technology
[0002] The greening and industrialization of highway bridge engineering has become a clear development trend. Prefabricated structures are widely recognized as an important way to achieve green construction due to their advantages such as energy saving, rapid construction, and controllable quality.
[0003] However, in highway interchange areas, bridges often exhibit complex alignment conditions such as small radii, varying widths, and bifurcated shapes. Traditional design methods struggle to effectively utilize standardized prefabricated components, resulting in a generally low rate of prefabricated construction in these areas. In existing technologies, designers often rely on experience to determine the feasibility of prefabrication, lacking scientific and rapid assessment tools. Furthermore, the prefabrication design process for curved beams and beams with varying widths is cumbersome, involves complex parameters, and suffers from low design efficiency, further hindering the widespread application of prefabricated technology.
[0004] This shows that existing technologies cannot quickly determine an economical design scheme for bridges. Summary of the Invention
[0005] In view of this, it is necessary to provide a method and related apparatus for determining bridge design schemes to solve the problem that existing technologies cannot quickly determine economical bridge design schemes.
[0006] To address the aforementioned problems, in a first aspect, the present invention provides a method for determining a bridge design scheme, comprising: Parametric calculations are performed on the standard prefabricated bridge general drawing to generate a parametric prefabricated bridge general drawing, and the range of control index parameters in the parametric prefabricated bridge general drawing is determined. Obtain the design parameters of the bridge to be designed, and generate an initial prefabricated scheme for the bridge to be designed based on the design parameters and the parametric prefabricated bridge general drawing. When the control index parameters in the initial prefabricated scheme are within the range of the control index parameters in the general drawing of parametric prefabricated bridges, the initial prefabricated scheme is determined as the design scheme of the bridge to be designed. When the control parameters in the initial prefabricated scheme are not within the range of control parameters in the general drawing of parametric prefabricated bridges, the control parameters of the initial prefabricated scheme are adjusted to generate a secondary prefabricated scheme. The design scheme of the bridge to be designed is then determined based on the cost of the secondary prefabricated scheme and the cast-in-place scheme.
[0007] In one possible implementation, parametric calculations are performed on the standard prefabricated bridge general drawing to generate a parametric prefabricated bridge general drawing, and the range of control index parameters in the parametric prefabricated bridge general drawing is determined, including: Obtain the control index parameters of each standard prefabricated component in the general drawings of standard assembled bridges; The allowable range of each control index parameter is adjusted based on the complexity of the bridge to be designed, and a parameterized general drawing of the prefabricated bridge is generated based on the allowable range of each control index parameter.
[0008] In one possible implementation, the design parameters of the bridge to be designed are obtained, and an initial prefabricated scheme for the bridge to be designed is generated based on the design parameters and a parametric prefabricated bridge general drawing, including: Obtain the span and roadbed width of the bridge to be designed; Based on the span and roadbed width, the beam and slab parameters of the bridge to be designed are determined by combining the allowable range of the control index parameters in the parametric prefabricated bridge general drawing. The beam and slab parameters include the number of beams and slabs, the size of each beam and slab, and the width of the wet joint between beams and slabs.
[0009] In one possible implementation, for the curved bridge segment of the bridge to be designed, an initial prefabricated scheme for the bridge to be designed is generated based on design parameters and a parametric prefabricated bridge general drawing, including: The fitted curve of the curved bridge segment is obtained by fitting the curve using mathematical geometry, and the boundary conditions for the straight beam placement of the curved bridge segment are determined based on the fitted curve. Based on the boundary conditions of the straight beam arrangement, the first mathematical relationship between the radius of curvature of the fitted curve and the beam-slab parameters is constructed. Based on the first mathematical relationship and the design parameters of the curved bridge segment, the beam-slab parameters of the curved bridge segment are determined.
[0010] In one possible implementation, for the widened bridge section of the bridge to be designed, an initial prefabricated scheme for the bridge to be designed is generated based on design parameters and a parametric prefabricated bridge general drawing, including: A second mathematical relationship between the bridge width variation and beam parameters is determined based on the starting and ending widths of the widened bridge section. The beam and slab parameters of the widened bridge section are determined based on the second mathematical relationship and the design parameters of the widened bridge section. Among them, the bifurcation widening structure of the widened bridge section in the beam and slab parameters is adjusted to a whole-span widening structure.
[0011] In one possible implementation, the control parameters of the initial prefabricated scheme are adjusted to generate a secondary prefabricated scheme, including: The control parameters that are not within the range of control parameters in the initial prefabricated scheme of the parametric prefabricated bridge general drawing are adjusted to generate a secondary prefabricated scheme. In the secondary prefabricated scheme, all control parameters are within the range of control parameters in the parametric prefabricated bridge general drawing.
[0012] In one possible implementation, the design scheme of the bridge to be designed is determined based on the prices of the prefabricated secondary scheme and the cast-in-place scheme, including: When the cost of the prefabricated secondary construction scheme is greater than that of the cast-in-place scheme, the cast-in-place scheme will be selected as the design scheme for the bridge to be designed. When the cost of the secondary prefabricated scheme is less than or equal to the cost of the cast-in-place scheme, the secondary prefabricated scheme will be selected as the design scheme for the bridge to be designed.
[0013] Secondly, the present invention also provides a bridge design scheme determination device, comprising: The general drawing construction module is used to perform parametric calculations on the standard prefabricated bridge general drawing, generate parametric prefabricated bridge general drawings, and determine the range of control index parameters in the parametric prefabricated bridge general drawing. The scheme generation module is used to obtain the design parameters of the bridge to be designed, and generate an initial prefabricated scheme for the bridge to be designed based on the design parameters and the parametric prefabricated bridge general drawing. The first scheme determination module is used to determine the initial prefabricated scheme as the design scheme of the bridge to be designed when the control index parameters in the initial prefabricated scheme are within the range of the control index parameters in the parametric prefabricated bridge general drawing. The second scheme determination module is used to adjust the control parameters of the initial prefabricated scheme when the control parameters in the initial prefabricated scheme are not within the range of control parameters in the general drawing of parametric prefabricated bridges, generate a secondary prefabricated scheme, and determine the design scheme of the bridge to be designed based on the cost of the secondary prefabricated scheme and the cast-in-place scheme.
[0014] Thirdly, the present invention also provides an electronic device, including a memory and a processor, wherein, Memory, used to store programs; The processor, coupled to the memory, is used to execute a program stored in the memory to implement the steps in the bridge design scheme determination method of any of the above embodiments.
[0015] Fourthly, the present invention also provides a computer-readable storage medium for storing a computer-readable program or instructions, which, when executed by a processor, can implement the steps in the bridge design scheme determination method of any of the above embodiments.
[0016] The beneficial effects of this invention are as follows: The bridge design scheme determination method provided by this invention performs parametric calculations on design drawings applicable to constant roadbed widths, representing the structure and dimensions of the structure in the design drawings with parameters to obtain the design parameters of the bridge to be designed. Based on the design parameters and combined with the parametric prefabricated bridge general drawing, an initial prefabricated scheme for the bridge to be designed is generated. During the design of the prefabricated scheme, the parameter calculations enable rapid design, improving the design speed. When the initial prefabricated scheme meets the requirements, it is determined as the design scheme for the bridge to be designed; when the initial prefabricated scheme does not meet the requirements, it is adjusted according to the control index parameters to generate a secondary prefabricated scheme. The design scheme of the bridge to be designed is then determined based on the cost comparison between the secondary prefabricated scheme and the cast-in-place scheme, thus improving the economic efficiency of bridge construction.

Detailed Implementation
[0019] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.
[0020] In the description of the embodiments of the present invention, unless otherwise stated, "multiple" means two or more. "And / or" describes the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.
[0021] The terms "first," "second," etc., used in the embodiments of this invention are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a technical feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.
[0022] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0023] A specific embodiment of the present invention, such as Figure 1 As shown, a method for determining a bridge design scheme is disclosed, including: S101, Perform parametric calculations on the standard prefabricated bridge general drawing to generate a parametric prefabricated bridge general drawing, and determine the range of control index parameters in the parametric prefabricated bridge general drawing.
[0024] In this embodiment of the invention, the standard prefabricated bridge general drawing refers to the design drawing of prefabricated components designed for constant roadbed width. It enables the design of a prefabricated scheme for a constant roadbed width. By designing the road surface and bridge to be designed with a constant roadbed width as prefabricated beams of fixed dimensions, the beams are mass-produced in a beam manufacturing plant and then installed on the construction site, resulting in low cost and fast construction speed. For example... Figure 2 The diagram shown is a standard cross-sectional schematic diagram of a general prefabricated box girder drawing, which specifies the number of prefabricated box girders (n), the dimensions of the prefabricated box girders, and the width of the wet joint (s). However, for bridge interchange areas or variable-width roadbeds, the standard general prefabricated bridge drawing cannot adapt to changes in road width and cannot quickly generate a prefabricated scheme. Therefore, this invention generates a parametric general prefabricated bridge drawing by parametrically calculating the standard general prefabricated bridge drawing and adjusting the range of the control index parameters in the parametric general prefabricated bridge drawing. The control index parameters refer to parameters used to indicate whether the positional relationships between each prefabricated component in the prefabricated scheme meet the preset construction standards, including but not limited to the number of beams / slabs, beam / slab dimensions, and the width of the wet joint between beams / slabs. By adjusting the allowable range of the control index parameters in the standard general prefabricated bridge drawing, a parametric general prefabricated bridge drawing adaptable to interchange bridges is generated for subsequent design of prefabricated schemes for interchange bridges.
[0025] S102, Obtain the design parameters of the bridge to be designed, and generate the initial prefabricated scheme of the bridge to be designed based on the design parameters and the parametric prefabricated bridge general drawing.
[0026] In this embodiment of the invention, after constructing a parametric prefabricated bridge general drawing, based on the design parameters of the bridge to be designed, such as road width and span, and in conjunction with the parametric prefabricated bridge general drawing, the initial prefabricated scheme of the bridge to be designed can be rapidly generated through parametric calculations of the structure. The process of generating the initial prefabricated scheme will be described in detail later in this invention.
[0027] S103, when the control index parameters in the initial prefabricated scheme are within the range of the control index parameters in the parametric prefabricated bridge general drawing, the initial prefabricated scheme is determined as the design scheme of the bridge to be designed.
[0028] In this embodiment of the invention, for the initial prefabricated scheme generated by the aforementioned implementation, the range of each control index parameter in the initial prefabricated scheme is compared with the range of control index parameters in the general drawing of parametric prefabricated bridges. When the control index parameters in the initial prefabricated scheme are within the range of control index parameters in the general drawing of parametric prefabricated bridges, it indicates that the initial prefabricated scheme meets the construction requirements and the bridge design can be carried out directly according to the initial prefabricated scheme.
[0029] S104. When the control index parameters in the initial prefabricated scheme are not within the range of control index parameters in the general drawing of parametric prefabricated bridges, adjust the control index parameters of the initial prefabricated scheme to generate a secondary prefabricated scheme, and determine the design scheme of the bridge to be designed based on the cost of the secondary prefabricated scheme and the cast-in-place scheme.
[0030] In this embodiment of the invention, the initial prefabricated scheme generated in the aforementioned embodiments may not meet construction requirements. This is because, for a fixed range of bridge design parameters, the parametric prefabricated bridge general drawing provides a fixed initial prefabricated scheme, where the number and size of beams and slabs are fixed. This can lead to certain control parameters exceeding the range, such as excessively large or small wet joint widths. In this case, the initial prefabricated scheme needs to be modified to ensure that each control parameter in the secondary prefabricated scheme is within the range of control parameters in the parametric prefabricated bridge general drawing. However, the secondary prefabricated scheme differs from the initial prefabricated scheme and cannot guarantee economic efficiency. Therefore, it needs to be compared with the cost of the cast-in-place scheme to determine the final bridge design scheme. The cast-in-place scheme involves pouring concrete on-site for the bridge to be designed. While applicable to any construction scenario, the cost may be higher. When a prefabricated scheme is available and its cost is lower than that of the cast-in-place scheme, the prefabricated scheme is generally used in the design.
[0031] The bridge design scheme determination method provided by this invention involves parametric calculation of design drawings applicable to constant roadbed widths. The structure and dimensions of the structure in the design drawings are represented by parameters to obtain the design parameters of the bridge to be designed. Based on these design parameters and combined with a parametric prefabricated bridge general drawing, an initial prefabricated scheme for the bridge to be designed is generated. During the design of the prefabricated scheme, parameter calculations enable rapid design, improving the design speed. When the initial prefabricated scheme meets the requirements, it is determined as the design scheme for the bridge to be designed. When the initial prefabricated scheme does not meet the requirements, it is adjusted according to the control index parameters to generate a secondary prefabricated scheme. The design scheme for the bridge to be designed is then determined based on the cost comparison between the secondary prefabricated scheme and the cast-in-place scheme, selecting the scheme with the lower cost as the design scheme for the bridge to be designed, thereby improving the economic efficiency of bridge construction.
[0032] In some possible embodiments of the present invention, such as Figure 3 As shown, parametric calculations are performed on the standard prefabricated bridge general drawing to generate a parametric prefabricated bridge general drawing, and the range of control index parameters in the parametric prefabricated bridge general drawing is determined, including: S301, Obtain the control index parameters of each standard prefabricated component in the general drawing of standard assembled bridge; S302, adjust the allowable range of each control index parameter based on the complexity of the bridge to be designed, and generate a parameterized general drawing of prefabricated bridge based on the allowable range of each control index parameter.
[0033] In this embodiment of the invention, when constructing a parametric prefabricated bridge general drawing, the control index parameters of each standard prefabricated component in the standard prefabricated bridge general drawing can be obtained first. Then, the allowable range of the control index parameters is determined by combining the complexity of the bridge to be designed, such as the number of curve segments, the curvature of the curves, the length of the widened roadbed, and the widening value. Because each control index parameter in the standard prefabricated bridge general drawing is a fixed parameter group, and the value of each control index parameter in a parameter group is fixed, by modifying the allowable range of the control index parameters in each parameter group, the control index parameters in the parameter group are changed from fixed values to range values, thereby improving the applicability of the parametric prefabricated bridge general drawing to bridges in interchange areas. Specifically, the allowable range of key dimensions of standard prefabricated components can be optimized through system structural calculations, including expanding the variation range of wet joint width and beam length, improving its adaptability to bridges with variable width and small radius sections, thereby obtaining the parametric prefabricated bridge general drawing.
[0034] This invention provides a parametric prefabricated bridge general drawing, which facilitates the design of prefabricated bridge schemes for subsequent interchange areas.
[0035] In some possible embodiments of the present invention, such as Figure 4 As shown, the design parameters of the bridge to be designed are obtained, and an initial prefabricated scheme for the bridge to be designed is generated based on the design parameters and the parametric prefabricated bridge general drawing, including: S401, obtain the span and roadbed width of the bridge to be designed; S402. Based on the span and roadbed width, and combined with the allowable range of the control index parameters in the parametric prefabricated bridge general drawing, the beam and slab parameters of the bridge to be designed are determined. The beam and slab parameters include the number of beams and slabs, the size of each beam and slab, and the width of the wet joint between beams and slabs.
[0036] In this embodiment of the invention, the design parameters of the bridge to be designed include the span and the roadbed width. For bridges in interchange areas, the span and roadbed width may vary, and there may be curved sections. Therefore, when designing the initial prefabricated scheme, it is necessary to determine the beam and slab parameters of the bridge to be designed by combining the allowable range of the control index parameters in the parametric prefabricated bridge general drawing. That is, within the allowable range of the control index parameters, the beam and slab parameters of the bridge to be designed are determined, including but not limited to the number of beams and slabs, the size of each beam and slab, and the width of the wet joint between beams and slabs.
[0037] Furthermore, such as Figure 5As shown, for the curved bridge section of the bridge to be designed, an initial prefabricated scheme for the bridge to be designed is generated based on design parameters and a parametric prefabricated bridge general drawing, including: S501, by fitting the curve of the curved bridge segment through mathematical geometry, the boundary conditions for the straight beam placement of the curved bridge segment are determined based on the fitted curve. S502, based on the boundary conditions of the straight beam arrangement, construct the first mathematical relationship between the radius of curvature of the fitted curve and the beam-slab parameters, and determine the beam-slab parameters of the curved bridge segment based on the first mathematical relationship and the design parameters of the curved bridge segment.
[0038] In embodiments of the present invention, such as Figure 6 As shown, for curved bridge sections, a quantitative design method of "substituting straight lines for curves" is needed to design the beams and slabs. This involves simulating the bridge beam layout boundary conditions (span, curve radius, roadbed edge, etc.) of a planar circular curve using mathematical geometry, and establishing the first mathematical relationship between the radius of curvature and beam / slab parameters (including the number of beam segments, beam length, and wet joint width), as detailed below:
[0039]
[0040]
[0041]
[0042]
[0043] in, The length of the outermost beam. Let T be the length of the innermost side beam, R be the standard span, and n be the radius of curvature and the standard span. Let W be the central angle, and W be the length of the outer cantilever of the side beam. The outermost offset, The innermost offset, The outermost arch height, This is the innermost arch height.
[0044] In this embodiment of the invention, based on the above mathematical relationship and combined with the design parameters of the curved bridge segment to be designed, the beam and slab parameters of the curved bridge segment can be determined.
[0045] Furthermore, such as Figure 7 As shown, for the widened bridge section of the bridge to be designed, an initial prefabricated scheme for the bridge to be designed is generated based on design parameters and a parametric prefabricated bridge general drawing, including: S701, a second mathematical relationship between the bridge width variation value and beam parameters is determined based on the starting width and ending width of the widened bridge section; S702, based on the second mathematical relationship and the design parameters of the widened bridge section, determine the beam and slab parameters of the widened bridge section, wherein the bifurcation widening structure of the widened bridge section in the beam and slab parameters is adjusted to a whole-span widening structure.
[0046] In this embodiment of the invention, in conjunction with the preceding embodiment, such as Figure 8 As shown, for the widened bridge section of the bridge to be designed, the second mathematical relationship between the bridge widening value and the beam parameters is determined based on the starting and ending widths of the widened section, as follows:
[0047]
[0048]
[0049]
[0050]
[0051]
[0052] in, The length of the outermost beam after the beams are laid out. The length of the innermost side beam after the beams are laid out. B To make the bridge wider than the bridge beam, To widen the bridge after the beam is laid, To increase the width of the bridge at the starting point after the beam and slab, To increase the width of the wet joint at the rear end of the beam and slab, and These represent the maximum and minimum widths of the wet joint at the endpoint. To increase the width of the wet joint on the starting side of the beam and slab, The number of beams and slabs used after increasing the number of beams and slabs.
[0053] In this embodiment of the invention, based on the above mathematical relationship and combined with the design parameters of the widened bridge section to be designed, the beam and slab parameters of the widened bridge section can be determined.
[0054] Furthermore, by "extending the main cap beam to replace the bifurcation crossbeam," the bifurcation widening structure is transformed into a unified widening structure. Specifically, for example... Figure 9 As shown, the original bifurcated cast-in-place beam is the part of the zigzag cast-in-place beam shown in the figure, which will result in a zigzag structure in the beam and slab. This application addresses this by extending the main cap beam, i.e. Figure 9 The shared straight cap beam section will have its broken lines adjusted to straight lines for easier construction.
[0055] In some possible embodiments of the present invention, adjusting the control parameters of the initial prefabricated scheme to generate a secondary prefabricated scheme includes: The control parameters that are not within the range of control parameters in the initial prefabricated scheme of the parametric prefabricated bridge general drawing are adjusted to generate a secondary prefabricated scheme. In the secondary prefabricated scheme, all control parameters are within the range of control parameters in the parametric prefabricated bridge general drawing.
[0056] In this embodiment of the invention, taking a highway interchange bridge design project as the application background, as shown in Table 1, the general drawings for prefabricated low T-beams in this project are adjusted and optimized. The adaptable range of wet joint width is expanded to 35cm~60cm, and the allowable value of single-span beam length variation is expanded to ±0.8m, so as to improve adaptability to interchange widening sections. Similarly, the general drawings for prefabricated small box girders in this project are adjusted and optimized, expanding the adaptable range of wet joint width to 35cm~95cm, and the allowable value of single-span beam length variation to ±1.0m, to improve adaptability to interchange widening sections.
[0057] Table 1: General Control Indicators for Parametric Prefabricated Bridge Superstructure
[0058] Furthermore, such as Figure 10 As shown, designers input the design parameters of the bridge to be designed, and the system automatically calculates the control parameters of the prefabricated scheme, such as the maximum beam length, the width of the starting wet joint, and the width of the ending wet joint. The system then compares these control parameters with the aforementioned control indicators. If all indicators meet the general drawing requirements, the prefabricated scheme is deemed feasible. If the indicators do not meet the general drawing requirements, a second-order judgment is required. After the designers supplement the input parameters, the control parameters of the prefabricated scheme are recalculated, along with the changes in bridge area after the second-order design, such as increasing the amount of clinker in the beams and reducing the beam dimensions to decrease the width of the wet joints.
[0059] In embodiments of the present invention, such as Figure 11 As shown, the design scheme for the bridge to be designed is determined based on the prices of the prefabricated and cast-in-place schemes, including: S1101, When the cost of the secondary prefabricated scheme is greater than that of the cast-in-place scheme, the cast-in-place scheme shall be determined as the design scheme for the bridge to be designed. S1102, when the cost of the secondary prefabricated scheme is less than or equal to the cost of the cast-in-place scheme, the secondary prefabricated scheme shall be determined as the design scheme for the bridge to be designed.
[0060] In this embodiment of the invention, the number and size of beams and slabs in the secondary prefabrication scheme may change, thus affecting the cost. Therefore, a cost assessment is necessary. This involves calculating the changes in bridge area and comparing the total cost of the secondary prefabrication scheme with that of the cast-in-place scheme based on the unit prices of the different built-in structural schemes. If the total cost of the secondary prefabrication scheme is lower, it is recommended, and relevant design parameters are output. If the total cost of the cast-in-place scheme is lower, it is recommended.
[0061] The embodiments of the present invention fully consider the economic advantages of prefabricated and cast-in-place methods, thereby reducing bridge construction costs.
[0062] To better implement the bridge design scheme determination method in the embodiments of the present invention, based on the bridge design scheme determination method, correspondingly, as follows: Figure 12 As shown, this embodiment of the invention also provides a bridge design scheme determination device, the bridge design scheme determination device 1200 comprising: The general drawing construction module 1201 is used to perform parametric calculations on the standard prefabricated bridge general drawing, generate a parametric prefabricated bridge general drawing, and determine the range of control index parameters in the parametric prefabricated bridge general drawing. The scheme generation module 1202 is used to obtain the design parameters of the bridge to be designed, and generate an initial prefabricated scheme of the bridge to be designed based on the design parameters and the parametric prefabricated bridge general drawing. The first scheme determination module 1203 is used to determine the initial prefabricated scheme as the design scheme of the bridge to be designed when the control index parameters in the initial prefabricated scheme are within the range of the control index parameters in the parametric prefabricated bridge general drawing. The second scheme determination module 1204 is used to adjust the control parameters of the initial prefabricated scheme when the control parameters in the initial prefabricated scheme are not within the range of control parameters in the parametric prefabricated bridge general drawing, generate a secondary prefabricated scheme, and determine the design scheme of the bridge to be designed based on the cost of the secondary prefabricated scheme and the cast-in-place scheme.
