[0002] The arrangement of bridge spans is a crucial aspect of bridge design, directly impacting construction costs, construction difficulty, and structural safety. Currently, the traditional method widely used in the industry relies primarily on experienced engineers for manual planning and adjustments. While this method ensures basic feasibility, it is inefficient and struggles to find the globally optimal or near-optimal economic solution within a limited timeframe when facing complex terrain, multiple obstacles (such as rivers and roads), and stringent technical specifications (such as standard span requirements). Summary of the Invention

[0022] Figure 1 An exemplary system architecture 100 is shown, in which embodiments of the bridge span arrangement design method or bridge span arrangement design apparatus of this disclosure can be applied.

[0023] like Figure 1 As shown, system architecture 100 may include terminal devices 101, 102, and 103, a network 104, and a server 105. Network 104 serves as the medium for providing communication links between terminal devices 101, 102, and 103 and server 105. Network 104 may include various connection types, such as wired or wireless communication links, or fiber optic cables, etc.

[0024] Users can use terminal devices 101, 102, and 103 to interact with server 105 via network 104 to receive or send messages, etc. Various communication client applications, such as data processing applications and bridge design applications, can be installed on terminal devices 101, 102, and 103. Terminal devices 101, 102, and 103 can send relevant information about the target bridge to server 105 via network 104.

[0025] Terminal devices 101, 102, and 103 can be either hardware or software. When terminal devices 101, 102, and 103 are hardware, they can be various electronic devices, including but not limited to smartphones, tablets, in-vehicle computers, laptops, and desktop computers.

They can be implemented as multiple software programs or software modules (e.g., to provide distributed services) or as a single software program or software module. No specific limitations are imposed here.

After processing the relevant data, the backend server can determine the target bridge design scheme and feed it back to each terminal device 101, 102, and 103.

[0027] It should be noted that server 105 can be either hardware or software. When server 105 is hardware, it can be implemented as a distributed server cluster consisting of multiple servers, or as a single server. When server 105 is software, it can be implemented as multiple software programs or software modules (for example, used to provide distributed services), or as a single software program or software module. No specific limitations are made here.

[0028] It should be noted that the bridge span arrangement design method provided in this embodiment can be executed by terminal devices 101, 102, and 103, or by server 105. Accordingly, the bridge span arrangement design device can be installed in terminal devices 101, 102, and 103, or in server 105.

[0029] It should be understood that Figure 1 The number of terminal devices, networks, and servers shown is merely illustrative. Depending on implementation needs, any number of terminal devices, networks, and servers can be included.

[0030] Figure 2 A flow chart 200 illustrating an embodiment of the bridge span arrangement design method of this disclosure is shown. For example... Figure 2 As shown, the bridge span arrangement design method in this embodiment may include the following steps:

[0031] Step 201: Obtain the starting area, ending area, obstacle area, beam element information, and recommended span rules of the target bridge.

[0032] In this embodiment, the entity executing the bridge span arrangement design method (e.g.) Figure 1 The terminal devices 101, 102, 103 or shown Figure 1The server 105 shown can obtain the starting area, ending area, obstacle area, beam element information, and recommended span rules for the target bridge. The target bridge is the bridge to be designed. The starting area can be the area where the starting point of the target bridge is located, and the ending area can be the area where the ending point of the target bridge is located. The range of the starting and ending areas can be preset. In some specific implementations, the starting and ending areas can be located on opposite banks of a river. The obstacle area can be the area containing obstacles between the starting and ending areas, or an area that needs to be avoided. For example, it could be a waterway in a river or a reef area in the sea. The beam element information can indicate how many spans a beam element has and the span length of each span. The recommended span rules can include: beam element, recommended span for crossing obstacles, the length range of the obstacles to be crossed, and whether the rule is mandatory. For example, the recommended span rules could include: a continuous beam with a recommended span of (40.85+64+40.85) meters, using a 64-meter span to forcibly cross obstacles with a length range of 50 to 56 meters.

[0033] Step 202: Determine the fixed and non-fixed sections of the target bridge based on the starting area, ending area, obstacle area, and beam unit information.

[0034] After obtaining the above information, the fixed and non-fixed intervals of the target bridge can be determined based on the starting area, ending area, and obstacle area. Specifically, the interval between the starting area and the obstacle area can be considered a non-fixed interval, while the area surrounding the obstacle area can be considered a fixed interval. Alternatively, the fixed interval can be determined based on the beam element information and the obstacle area. Within the interval between the starting and ending areas, all intervals except the fixed intervals are non-fixed intervals. It should be noted that the fixed intervals here are not absolutely fixed; that is, the start and end points of the fixed intervals are not absolutely fixed. The start and end points of the fixed intervals can vary within a specified range, or the fixed intervals can be changed under specified conditions. For example, if a bridge design scheme without non-standard spans cannot be explored based on the current fixed and non-fixed intervals, the fixed intervals can be changed. When changing the fixed intervals, the start and / or end points of the fixed intervals can be changed.

[0035] Step 203: Determine multiple bridge design schemes based on recommended span rules, fixed sections, and non-fixed sections.

[0036] After determining the fixed and non-fixed spans, multiple bridge design schemes can be determined by further combining recommended span rules. Specifically, the starting point can be determined first within the initial area, for example, by randomly selecting a point within the initial area. Then, based on the specific information in the recommended span rules, the pier positions are explored within the non-fixed span, starting from the starting point. Simultaneously, the pier positions are determined by combining the boundaries of the fixed spans. Alternatively, the pier positions within the fixed spans can be determined based on the length of the fixed span or the location of obstacles. After determining the pier positions within both the fixed and non-fixed spans, a bridge design scheme is obtained. Through multiple explorations of pier positions, multiple bridge design schemes can be obtained. For example, if the recommended span rules specify a span length of 60 meters and stipulate that this rule must be followed, then the pier positions need to be determined within either the non-fixed or fixed spans, starting from the starting point and exploring in 60-meter increments.

[0037] Step 204: Determine the target bridge design scheme based on the evaluation indicators corresponding to each bridge design scheme.

[0038] After identifying multiple bridge design schemes, a target bridge design scheme can be selected. Specifically, evaluation indicators for each bridge design scheme can be determined. These indicators may include parameters such as cost, construction time, and construction process. Weighted averages can be applied to these parameters to obtain the values ​​of the evaluation indicators. Then, based on these values, the target bridge design scheme can be determined. For example, the bridge design scheme with the lowest total cost among all schemes can be selected as the target bridge design scheme. Alternatively, the bridge design scheme with the shortest distance among all schemes can be selected as the target bridge design scheme. Here, the target bridge design scheme can be the lowest-cost bridge design scheme, the bridge design scheme with the optimal evaluation indicators, or a series of bridge design schemes that meet the given conditions.

[0039] Step 205: Output the target bridge design scheme.

[0040] Once the target bridge design scheme is determined, it can be exported. When exporting, it can be in a specific format to allow users to view the target bridge design scheme more clearly.

[0041] The bridge span arrangement design method provided in the above embodiments of this disclosure can first obtain the starting region, ending region, obstacle region, beam element information, and recommended span rules of the target bridge. Based on the starting region, ending region, and obstacle region, fixed and non-fixed intervals of the target bridge are determined. Further, based on the fixed and non-fixed intervals, multiple bridge design schemes are determined. Finally, based on the evaluation indicators corresponding to each bridge design scheme, the target bridge design scheme is determined from the multiple bridge design schemes and output. Through the scheme of this disclosure, the efficiency of determining the globally optimal or near-optimal bridge design scheme can be effectively improved.

[0042] See also Figure 3 This illustrates flow 300 of another embodiment of the bridge span arrangement design method according to this disclosure. (See also...) Figure 3 As shown, the method in this embodiment may include the following steps:

[0043] Step 301: Obtain the starting area, ending area, obstacle area, beam element information, and recommended span rules for the target bridge.

[0044] In some practical applications, after obtaining the starting area, ending area, obstacle area, beam element information, and recommended span rules of the target bridge, the data can first be structured to obtain structured data. Specifically, during the structuring process, the data can be formatted into a format that subsequent algorithms can process. For example, if an ant colony algorithm is subsequently used for processing, the structured data will be the data class internal to the ant colony algorithm.

[0045] Step 302: Determine the fixed and non-fixed sections of the target bridge based on the starting area, ending area, obstacle area, and beam unit information.

[0046] In this embodiment, after structuring the above data, the structured data can be input into the algorithm. The algorithm can determine fixed and non-fixed intervals of the target bridge based on the starting region, ending region, obstacle region, and beam unit information. Specifically, the executing entity can determine fixed intervals based on beam unit information and obstacle regions. For example, if the length of a single span in the beam unit information is greater than the obstacle region, a fixed interval can be set around this obstacle region. Alternatively, the fixed interval can be determined based on the size of the obstacle region. That is, if the obstacle region is larger than a preset value, then the obstacle region is set as a fixed interval. If the obstacle region is smaller than a preset value, then the obstacle region is set as a non-fixed interval. A non-fixed interval can be any interval in the line connecting the starting region and the ending region, excluding the obstacle region and the fixed interval. The relationship between fixed and non-fixed intervals can be as follows: Figure 4 As shown.

[0047] In some specific practices, the dimensions of standard simply supported beam elements, continuous beam elements, and special beam elements can be pre-defined. Based on obstacle information (such as location and size), the recommended beam element span dimensions, beam span type, span length, and beam element information are determined. If the recommended beam element is determined to be the only option based on obstacle information, then this option can be designated as the mandatory option, and the area containing this beam element becomes a fixed interval.

[0048] If the recommended beam element is not the only option, the recommended beam elements can be ranked according to priority. Understandably, the beam element with the highest priority will be ranked first.

[0049] Step 303: When determining the first bridge design scheme, starting from the starting area, explore the pier locations in a non-fixed interval according to the recommended span rules; for each determined bridge design scheme, determine the heuristic information, pheromone, and reward value according to the bridge design scheme; explore the pier locations in a non-fixed interval according to the recommended span rules, heuristic information, pheromone, and reward value to obtain a new bridge design scheme.

[0050] After determining the fixed and non-fixed intervals, we can start from the initial region and explore the pier locations within the non-fixed intervals according to the recommended span rules. Specifically, we can use an ant colony algorithm to determine the pier locations based on the length range of obstacles to be crossed in the recommended span rules. When using the ant colony algorithm, structured data can be input into it, allowing the ants to explore the pier locations starting from the initial region based on the parameters in the structured data.

[0051] During the exploration of bridge pier locations, when determining the first bridge design scheme, one can start from the initial area and explore pier locations within a non-fixed interval according to the recommended span rules. After determining the first bridge design scheme, heuristic information, pheromones, and reward values ​​can be assigned to each determined bridge design scheme.

[0052] In ant colony optimization (ACO), pheromones are chemical substances left by ants on their paths, used to transmit information and mark routes. Each ant leaves pheromones on its path based on the path's quality (e.g., length, cost, time). Paths with higher pheromone concentrations are more likely to be chosen by other ants, creating a positive feedback mechanism. Heuristic information refers to additional information that helps ants make choices during the decision-making process. This is usually a characteristic of the problem itself; for example, cost can be used as heuristic information in a minimum-cost problem. The reward value refers to the degree of reward for a path. A higher reward value indicates a more recommended path. The reward value is determined by a reward function that assigns different rewards based on the degree of matching between the current span and the standard simply supported beam span. A higher matching degree results in a larger reward value. Each path determined by the ant colony optimization can be considered a bridge design scheme. Each node in the path can be understood as the location of a pier in the bridge design scheme.

[0053] After determining the design schemes for each bridge, the location of the piers can be explored in a non-fixed range based on the recommended span rules, heuristic information, pheromones, and reward values, thereby obtaining new bridge design schemes.

[0054] In some optional implementations of this embodiment, heuristic information can be determined based on the cost corresponding to the bridge design scheme, the degree of matching with the standard span, and the degree of avoidance of obstacle areas.

[0055] In this implementation, heuristic information can be expressed as η. ij Let represent and define η as . ij =f cost (C ij ) ×f match (L ij ) × f obstacle (P j ), where C ij L represents cost. ij It is the span length, P j It refers to the location of the bridge pier, f cost (C ij ) represents the cost coefficient, f match (L ij ) represents the matching degree, f obstacle (P j () indicates the degree of avoidance.

[0056] In some optional implementations of this embodiment, after determining each bridge design scheme, a pheromone increment can be determined for that bridge design scheme. Specifically, the pheromone increment can be determined based on the cost corresponding to the bridge design scheme. The current pheromone value of the bridge design scheme can also be determined. The pheromone level of the bridge design scheme is then updated based on the pheromone increment and the current pheromone value. Bridge design schemes with lower costs have larger pheromone increments along their paths. The pheromone increment is defined as Deta. ij = Q / C total Where Q is a constant, and C total This represents the total cost of the bridge design scheme. After determining the pheromone increment, the pheromone content of the bridge design scheme can be updated based on the initial value and the aforementioned pheromone increment.

[0057] In some optional implementations of this embodiment, the reward value can also be determined based on the matching degree between the bridge design scheme and the standard span. The greater the matching degree, the greater the reward value. In some specific practices, a quadratic function can be designed as the reward function, such that when the deviation |L-Lstd| between the span L and the standard span Lstd approaches 0, the reward value output by the reward function increases exponentially.

[0058] Step 304: In response to determining that the new bridge design scheme includes non-standard spans, adjust the position of the fixed section within a preset range; determine the updated non-fixed section based on the updated position of the fixed section; determine the new bridge design scheme based on the recommended span rules, the updated fixed section, and the updated non-fixed section, until the new bridge design scheme does not include non-standard spans.

[0059] Once a new bridge design is determined, if the new design includes non-standard spans, the location of the fixed section can be updated. Specifically, the location of the fixed section can be adjusted within a preset range. This preset range can be the area surrounding the boundary of the fixed section, or it can be the entire area where the fixed section is located.

[0060] After determining the location of the updated fixed span, the updated non-fixed span can be identified. Further, based on the recommended span rules, the updated fixed span, and the updated non-fixed span, a new bridge design scheme is determined until the new bridge design scheme does not include non-standard spans. This ensures that the bridge design scheme does not include non-standard spans as much as possible.

[0061] In some optional implementations of this embodiment, after updating the fixed interval, a starting point can be determined first within the starting region, and an ending point can be determined simultaneously within the ending region. Then, based on the starting point, ending point, and the position of the updated fixed interval, an updated non-fixed interval is determined. When determining the starting point and ending point, they can be randomly determined within the starting and ending regions, or the ending point can be determined within the ending region based on a preset distance after the starting point has been determined.

[0062] Step 305: Update the pheromones in real time according to the preset pheromone decay law.

[0063] In ant colony optimization, pheromones are released in real time. In this embodiment, the pheromones of each bridge design scheme need to be updated in real time. Specifically, the pheromones can be updated according to a preset pheromone decay rule. For example, they can be updated at a rate of one-third decay per second.

[0064] Step 306: Determine the target bridge design scheme based on the evaluation indicators corresponding to each bridge design scheme.

[0065] After exploring and obtaining multiple bridge design schemes, evaluation indicators for each scheme can be calculated. Specifically, the bridge design scheme with the lowest cost can be determined as the target bridge design scheme. Cost calculation can be performed by adding the costs of each span in the bridge design schemes. The target bridge design scheme can be defined as follows: Figure 5 As shown.

[0066] Step 307: Verify the target bridge design scheme; in response to successful verification, determine the starting point and ending point of the target bridge based on the target bridge design scheme; output the target bridge design scheme in a preset format.

[0067] After obtaining the target bridge design scheme, it can be verified. Specifically, the target bridge design scheme can be compared with existing bridge construction experience. If the target bridge design scheme is determined to be feasible, it is considered to have passed verification. After verification, the starting and ending points of the target bridge can be determined based on the target bridge design scheme. It is understood that the starting and ending points may differ for different bridge design schemes. However, the starting points for each bridge design scheme should all be located within the starting area, and similarly, the ending points for each bridge design scheme should all be located within the ending area. The final starting and ending points can be determined through the target bridge design scheme.

[0068] To facilitate technical personnel's review of the target bridge design scheme, relevant information can be output in a preset format. This information may include pier locations, minimum cost, beam sequence used, and detailed information on non-standard spans. In some practical applications, historical bridge construction experience or comparisons between non-standard and standard spans in the target bridge design scheme can be used to determine optimization suggestions for the target bridge design scheme. Along with the target bridge design scheme, optimization suggestions and construction recommendations are also output.

[0069] The bridge span arrangement design method provided in the above embodiments of this disclosure, by introducing an ant colony algorithm, can efficiently find the optimal solution in a huge search space, significantly reducing manual intervention and design time. The algorithm provides a flexible configuration interface, supporting user-defined span recommendation rules, beam element priorities, and matching tolerances to adapt to different design requirements. It can comprehensively handle multiple complex constraints within a unified framework, ensuring the rationality and feasibility of the final solution. The system can automatically identify non-standard spans and provide optimization suggestions based on the closest standard span, facilitating rapid adjustments by engineers.
