[0029] In related technologies, in order to improve the efficiency of subway construction in cities, it is necessary to plan the construction site in advance through 3D modeling. However, due to the complex environment of some urban areas and the high requirements of relevant industry standards for site planning, the existing urban construction site layout planning methods are difficult to adapt to the complex environment and also difficult to meet the requirements of relevant industry standards while ensuring modeling efficiency during the modeling stage, thus failing to meet user needs.

[0030] To address the aforementioned issues, this disclosure provides a method and apparatus for site layout of temporary engineering projects in complex urban environments. The method involves acquiring topographic spatial data, site layout condition data, a pre-set 3D model, and pipeline data of the site layout area. Based on the topographic spatial data and condition data, an initial site layout plan is generated. Based on the initial site layout plan and pipeline data, pipeline avoidance planning is performed to obtain the final site layout plan. Based on the site layout plan and the 3D model, 3D modeling is performed to generate an initial 3D site layout model. The initial 3D site layout model is then adjusted to obtain a final 3D site layout model. This allows for the efficient generation of a 3D site layout model that meets user needs, taking into account urban topographic spatial information and site layout conditions.

[0031] Figure 1 This is a flowchart illustrating a site layout method for temporary works in complex urban environments, according to an exemplary embodiment, such as... Figure 1 As shown, it should be noted that the site layout method for temporary works in complex urban environments in this application embodiment is applied to the site layout method for temporary works in complex urban environments. For example... Figure 1 As shown, the method may include the following steps:

[0032] Step 101: Obtain the topographic spatial data of the site layout area, the site layout condition data, the preset three-dimensional model, and the pipeline data.

[0033] In some embodiments of this application, the three-dimensional model is obtained from a pre-established model library, which includes multiple sub-model libraries, each storing different types of models. The models stored in the model library are used for forward design of the site layout. The model includes parameter information corresponding to the model.

[0034] In one embodiment, the model library may include a dynamic model library and a static model library. The static model library may include models of commonly used mechanical equipment, infrastructure, temporary facilities, plants, construction workers, roads, signs, and other standard-sized model components for the site. The parametric model library may include adjustable-size steel bar processing shed models, customizable living area models, flexibly laid-out office area models, and customizable promotional signage models.

[0035] In some embodiments of this application, the site layout condition data may include site layout constraint information, which may include any one or more of the following: site layout forward design specifications, construction standards, project delivery requirements, safety specifications, environmental protection standards, general site construction specifications, and special site construction specifications. The above constraint information can be regularized to obtain structured data specific to the constraint conditions.

[0036] It should be noted that the above pipeline data can be pipeline design drawings and related configuration parameters of the pipeline, such as pipeline type and pipeline elevation.

[0037] Step 102: Generate an initial site layout plan based on terrain spatial data and condition data.

[0038] In some embodiments of this application, step 102 may specifically include the following steps:

[0039] Step a1: Obtain the available spatial area based on terrain spatial data.

[0040] In one embodiment, based on topographical spatial data, a preliminary coordinate range of the site layout area is determined, and an available space area is selected within this range. For example, the coordinate range of the approximate site layout area includes open space, buildings, and roads. The area corresponding to the buildings can be removed to obtain an available space area that includes open space and roads.

[0041] Step a2: Obtain site layout elements based on site layout condition data.

[0042] Understandably, the site layout data includes elements to be arranged, such as site equipment, diaphragm walls, and area fences.

[0043] Step a3: Arrange the site layout elements within the available space area to obtain at least one candidate site layout scheme.

[0044] In some embodiments, annealing or genetic algorithms can be used to arrange site layout elements within the available space area to obtain at least one candidate site layout scheme.

[0045] For example, each candidate site layout plan may include information on the layout of temporary facilities (office area, living area, material storage yard, etc.), information on the layout of major mechanical equipment, information on the planning of internal roads, and information on the location of temporary water and electricity access points.

[0046] It should be noted that the layout information in the candidate site layout plan can be represented by two-dimensional design drawings.

[0047] Step 103: Based on the initial site layout plan and pipeline data, perform pipeline avoidance planning to obtain the site layout plan.

[0048] Understandably, the construction of a subway requires excavation of the original site, thus necessitating pipeline avoidance planning based on the initial site layout plan and pipeline data to obtain the site layout plan.

[0049] In some embodiments of this application, step 103 may specifically include the following steps:

[0050] Step b1: Export the initial site layout plan and pipeline data as first data supported by the first software; wherein, the first software has the function of pipeline avoidance planning.

[0051] In one embodiment, a second software can be used to generate an initial site layout plan based on terrain spatial data and condition data, and the initial site layout plan and pipeline data can be exported as first data supported by the first software, so that the first software can perform pipeline avoidance planning based on the initial site layout plan and pipeline data.

[0052] Step b2: Input the first data into the first software and obtain the second data output by the first software.

[0053] Step b3: Obtain the site layout plan based on the second data.

[0054] In one embodiment, first data is input into first software, which performs pipeline avoidance planning based on the first data to obtain second data. A site layout plan is then obtained based on the second data.

[0055] In some embodiments of this application, step 103 may specifically include the following steps:

[0056] Step c1: Based on the initial site layout scheme and pipeline data, perform collision detection on the pipelines corresponding to the pipeline data and the initial site layout scheme to obtain the conflict points between the first model and the pipelines in the initial site layout scheme.

[0057] Step c2: Based on the conflict points, the pipelines are avoided to obtain the pipeline layout scheme after the avoidance treatment.

[0058] In one embodiment, based on the initial site layout plan and pipeline data, collision detection is performed on the pipelines corresponding to the pipeline data and the initial site layout plan to find the conflict points between the first model and the pipelines in the initial site layout plan. The conflict points are added to the obstacle list of the pipeline path planning algorithm, and the pipeline path is replanned using the path planning algorithm to obtain a new pipeline path. The pipeline layout plan is updated based on the new pipeline path, that is, the pipeline is avoided to obtain the pipeline layout plan after the avoidance processing.

[0059] In one embodiment, the path planning algorithm can be the A* algorithm.

[0060] In another embodiment, a tiered avoidance strategy can be used to allow pipelines to avoid conflict points.

[0061] Step c3: The pipeline layout scheme and the initial site layout scheme are merged to obtain the site layout scheme.

[0062] In some embodiments of this application, the site layout condition data includes zoning constraints for functional partitioning of the site layout area. The initial site layout scheme includes functional partitions that satisfy the zoning constraints. Before step 103, the method may further include the following steps:

[0063] Based on the pipeline data and the functional classification of the functional zones in the initial site layout plan, a pipeline model associated with the functional zones is generated.

[0064] For example, functional areas may include offices, meeting rooms, archives, dormitories, canteens, shower rooms, and toilets.

[0065] It is understandable that, since different functional areas have different pipeline requirements, a pipeline model associated with the functional area can be generated based on the pipeline data and the functional classification of the functional area in the initial site layout plan.

[0066] In some embodiments of this application, after step 103, the following steps may also be included:

[0067] Step d1: Using the analytic hierarchy process (AHP), a risk assessment is conducted on the initial site layout plan based on multiple preset evaluation index values ​​to obtain the risk assessment results.

[0068] In one embodiment, the risk assessment of the initial site layout plan can be performed based on the risk factor weight calculation of the Analytic Hierarchy Process (AHP) according to multiple preset evaluation index values, and the risk assessment results can be obtained.

[0069] Step d2: Based on the risk assessment results and the initial site layout plan, plan the emergency evacuation routes for the site layout area to obtain the route planning results.

[0070] In one embodiment, a crowd evacuation scenario can be simulated based on cellular automata, and a multi-objective evacuation path optimization algorithm can be used to perform dynamic path planning that takes into account obstacles and congestion.

[0071] Step d3: Based on the risk assessment results, generate safety warning sign models at the corresponding locations in the route planning results.

[0072] In one embodiment, a safety warning sign model can be generated in areas where the risk assessment value is greater than a preset threshold.

[0073] Step d4: The safety warning sign model is fused with the initial site layout plan to obtain the fused initial site layout plan.

[0074] Step 104: Based on the site layout plan and the 3D model, perform 3D modeling to generate an initial 3D site layout model.

[0075] In one embodiment, the above-mentioned three-dimensional model is arranged according to the site layout plan to generate an initial three-dimensional site layout model.

[0076] In some embodiments of this application, step 104 may specifically include the following steps:

[0077] Step e1: Obtain the layout elements in the site layout plan and select a 3D model that matches the layout elements.

[0078] Step e2: Arrange the three-dimensional model based on the candidate site layout scheme to obtain the initial three-dimensional site layout model.

[0079] In one embodiment, all layout elements in a two-dimensional site layout scheme are obtained, a three-dimensional model matching the layout elements is selected from the model library, and the three-dimensional model is arranged based on the candidate site layout scheme to obtain an initial three-dimensional site layout model.

[0080] In some embodiments of this application, step e2 may specifically include the following steps:

[0081] Obtain the 3D model corresponding to the site layout elements from a pre-established model library; or,

[0082] Obtain the first model corresponding to the imported site layout elements, and convert the format of the first model to obtain the three-dimensional model.

[0083] It is understandable that the first model imported from other paths outside the system may have a different format than the 3D models in the model library. In order to better adapt the first model to the 3D models in the model library, it is necessary to convert the format of the first model.

[0084] In some embodiments of this application, step 104 may specifically include the following steps:

[0085] Obtain the predicted transport volume and traffic flow for different types of materials in the site layout area;

[0086] Determine storage areas for different types of materials based on transportation volume forecasts;

[0087] Based on the storage area and traffic flow forecast, the transportation routes of the site layout area are planned to obtain the transportation routes in the initial site layout scheme.

[0088] It is understandable that, since different types of materials have different requirements, weights, and uses, the transportation routes in the site layout area can be planned based on the storage area and traffic flow forecast to obtain the transportation routes in the initial site layout plan.

[0089] In one embodiment, any one or more of the following algorithms can be used for route planning of the transportation route: genetic algorithm, ant colony algorithm, or annealing algorithm.

[0090] Step 105: Adjust the initial three-dimensional site layout model to obtain the three-dimensional site layout model.

[0091] In some embodiments of this application, the site layout condition data also includes decoration requirement constraints for different functional zones of the site layout area. After step 105, the following steps may also be included:

[0092] For the target functional zones in the 3D site layout model, determine the decoration requirement constraints corresponding to the target functional zones; based on the decoration requirement constraints corresponding to the target functional zones, generate decoration schemes for the target functional zones.

[0093] The renovation plan includes at least one or more of the following: office space layout information, furniture placement information, lighting design information, and color matching information.

[0094] In one implementation, office space layout information can be generated based on a rule-based automatic layout algorithm, enabling dynamic space division and adjustment. An interactive layout editing tool will be designed: a drag-and-drop layout adjustment interface will be developed, enabling intelligent alignment and snapping functions; a layout constraint and rule checking system will also be developed. Collaborative design functionality will be implemented: real-time multi-user collaboration will be enabled, a version control and modification history system will be developed, and design review and annotation functions will be implemented.

Implement interactive furniture editing: develop furniture rotation, scaling, and combination functions. Enable customization of furniture materials and colors. Develop furniture set / combination functionality.

It designs intelligent color matching algorithms: generating harmonious color schemes based on color theory, developing a color recommendation system that considers spatial atmosphere, and generating color schemes based on brand standards. Furthermore, it implements color visualization and simulation: developing real-time material replacement and preview functions, simulating color under different lighting conditions, and developing a color blindness mode and accessibility checking tools.

[0098] In addition, we will conduct space utilization efficiency analysis to achieve accurate area and volume calculations, develop dynamic space utilization statistics, and enable custom area division and analysis. We will develop a graph theory-based pedestrian flow simulation algorithm to identify and visualize hotspot areas, and develop a space syntax-based accessibility analysis system. We will also develop a multi-scheme parallel comparison tool to compare the effects of historical versions, and an industry standard benchmarking analysis system.

[0099] Utilizing daylighting and ventilation simulation information, this project aims to calculate solar trajectories based on geographic location and time, develop a dynamic sky model (CIE standard sky), and perform solar radiation analysis and shadow projection simulation. It also includes developing a lighting uniformity analysis tool to assess glare and implement control strategies, a smart lighting control scheme generator, and a CFD-based airflow simulation to evaluate the effectiveness of natural ventilation. Finally, it develops an air quality prediction and optimization recommendation system.

[0100] In some embodiments of this application, after step 105, the following steps may also be included:

[0101] The three-dimensional site layout model is evaluated according to preset indicators, and the evaluation results are obtained.

[0102] Obtain a preset evaluation report template and generate an evaluation report based on the template and evaluation results.

[0103] In one embodiment, a template-based report generator can be used to interpret the data in the evaluation results and generate an evaluation report based on the evaluation report template and the evaluation results. Alternatively, an insight extraction algorithm can be used to extract the data in the evaluation results to obtain an interactive web report.

[0104] In some embodiments, the evaluation report can be updated accordingly based on changes in the evaluation results.

[0105] According to the site layout method for temporary projects in complex urban environments proposed in this application, the method acquires topographic spatial data, site layout condition data, a preset three-dimensional model, and pipeline data of the site layout area. Based on the topographic spatial data and condition data, an initial site layout plan is generated. Based on the initial site layout plan and pipeline data, pipeline avoidance planning is performed to obtain the site layout plan. Based on the site layout plan and the three-dimensional model, three-dimensional modeling is performed to generate an initial three-dimensional site layout model. The initial three-dimensional site layout model is adjusted to obtain a three-dimensional site layout model. Thus, considering urban topographic spatial information and site layout conditions, a three-dimensional site layout model that meets user needs can be efficiently generated.
