[0022] As shown in the figure, Figs. 1-2 The seabed geological parameter fusion photovoltaic foundation construction resource allocation method comprises the following steps: S1: The seabed topographic data, rock-soil physical parameters and stratum bearing capacity parameters of the construction sea area are synchronously obtained by a shipborne multi-beam sounding system, a seabed drilling sampling device and a static sounding device, specifically: S11, seabed topographic data acquisition and processing: the shipborne multi-beam sounding system arranged on the bottom of the survey ship is used to perform full-coverage scanning on the construction sea area according to a preset survey line scheme.

[0031] Through the above detection, the geotechnical physical parameters of each grid point core are generated, including porosity, saturation, and permeability coefficient.
[0032] S13, Stratum Bearing Capacity Parameter Extraction: In the range of about 2-3 meters adjacent to each seabed drilling sampling device arranged in S12, a static cone penetrometer is arranged to carry out in-situ penetration test, with a penetration depth of 10 meters and a penetration speed controlled at 20 mm / s.
[0033] The following curve data are recorded in real time: cone tip resistance curve, side wall friction resistance curve, and the curve data are normalized according to the penetration depth to output standardized profile data.
[0034] The stratum bearing capacity parameters are calculated, including unconsolidated shear strength and bearing ratio (specific penetration resistance).
[0035] The unconsolidated shear strength is calculated as: ; wherein, is the cone tip resistance, is the total vertical stress, is the resistance coefficient, usually with a value range of 15-20 (recommended value for clayey deposits is 18); Bearing ratio (specific penetration resistance) Conversion: Then the Terzaqhi or Meyerhof formula is used to estimate the ultimate bearing capacity, or for foundation bearing capacity classification.
[0036] S14, Original Parameter Set Construction: The seabed topography data, geotechnical physical parameters and stratum bearing capacity parameters output in the above sub-steps are respectively associated with their sampling time and three-dimensional spatial coordinates to construct a unified parameter structure.

[0038] Finally, a set of spatio-temporally aligned original parameter sets are formed, providing basic data support for three-dimensional standardized modeling and comprehensive geological stiffness index calculation in subsequent steps.
[0039] S2: mapping each parameter in S1 to a three-dimensional geographic coordinate system to generate a standardized geological data cube with a timestamp, specifically: S21, geographic coordinate system conversion and spatial gridding: projecting and gridding each type of data in the spatio-temporally aligned original parameter set, the specific process is as follows: 1. Geographic coordinate conversion: WGS-84 three-dimensional geographic coordinate system is adopted as the unified reference; Each point cloud data coordinate in the seafloor topographic data is converted to geocentric coordinates; Synchronously convert the spatial sampling point coordinates of rock and soil physical parameters and stratum bearing capacity parameters to ensure the uniformity of the coordinate system.
[0040] 2. Spatial grid construction: Construct a regular three-dimensional spatial grid, with a grid cell length of .
[0041] Project and map the original sampling data to the corresponding spatial grid cells to generate three types of initial grid data: seafloor topographic grid data, rock and soil physical parameter grid data, and stratum bearing capacity parameter grid data.
[0042] S22, grid data dimensionless processing: to eliminate the influence of different parameter dimensions and improve the subsequent multi-source index fusion capability, three types of grid data are processed respectively, including: 1. Seafloor topographic grid data: elevation normalization method, expressed as: ; wherein, is the original water depth value (negative value represents seafloor depth), is the water depth value of the shallowest and deepest place in the entire region, and the standardized seafloor topographic data is output.
[0043] Grid data of geotechnical physical parameters: the following conversion is performed for each parameter (such as porosity, saturation, and permeability coefficient) respectively: ; Each normalized geotechnical physical parameter is reorganized into a standardized geotechnical physical parameter tensor.
[0044] Grid data of formation bearing capacity parameters: Z-score standardization method, expressed as: ; wherein X is the original bearing capacity parameter value, such as cone tip resistance, unconsolidated shear strength, and are the sample mean and standard deviation, respectively, and the output is the standardized formation bearing capacity parameter.
[0045] S23, fusion of standardized data and construction of a cube: the three types of standardized grid data are fused in space and time dimensions to construct the final standardized geological data cube, and the specific process is as follows: 1. Spatial fusion: according to the unified grid number , the standardized seabed topography value, geotechnical physical properties, and formation bearing capacity parameters in each unit are paired to ensure that each grid unit contains a set of three types of standardized values.
[0046] 2. Time matching: call the timestamp recorded in S14 , bind to each grid unit to ensure the spatio-temporal consistency of the data, and the time stamp accuracy is recommended to be controlled to the hour level to reflect the timeliness of the collection.
[0047] 3. Cube structure output: each standardized grid unit is represented as a structure, represented as: ; wherein the first four items are spatial and temporal information, and the subsequent items are standardized attribute data, and finally a standardized geological data cube including spatial coordinates, timestamps, and multi-dimensional geological attributes is formed.
[0048] S3: Extract the formation shear wave velocity, standard penetration number, and water content from the standardized geological data cube, and generate a comprehensive geological stiffness index for each grid unit through a weighted fusion algorithm, which is: S31, geological parameter extraction: extract the standardized formation shear wave velocity, standardized standard penetration number, and standardized water content from the standardized geological data cube according to the spatial grid unit.
[0049] S32, weight coefficient configuration and fusion model construction: to reflect the relative importance of each parameter to the stiffness contribution, the following preset weight coefficient range is set, and a fusion constraint model is established: standardized formation shear wave velocity weight coefficient , value range 0.45≤ ≤0.55; standardized SPT weight coefficient , value range 0.25≤ ≤0.35; standardized water content weight coefficient , value range 0.15≤ ≤0.25; The three need to meet the normalization constraint: ; In the present application = 0.5, = 0.3, = 0.2; S33, weighted fusion calculation and exponential matrix generation: for each spatial grid cell, apply the weighted fusion algorithm to calculate its comprehensive geological stiffness index . Denoted as: ; Wherein, is the comprehensive geological stiffness index of the grid cell, is the normalized formation shear wave velocity, N is the normalized SPT, and w is the normalized water content; Finally, the stiffness index of all grid cells is summarized to generate a comprehensive geological stiffness index value matrix: ; Wherein is the length, width and height distribution dimension of the spatial grid. The matrix serves as the input basis for the classification of geological construction units in S4, realizing the quantitative closed-loop support from original geological parameters to construction decision-making.
[0050] S4: According to the comprehensive geological stiffness index threshold, the construction sea area is divided into hard rock area, transition area and soft soil area three types of geological construction units, specifically: S41, set the comprehensive geological stiffness index threshold interval: to realize the classification of stiffness level, the relative threshold strategy is adopted to set the classification boundary of the comprehensive geological stiffness index matrix, including: 1. Extract the extreme value of the index: from the comprehensive geological stiffness index value matrix , respectively extract the global maximum value and the minimum value .
[0051] 2. Calculate the regional classification threshold: hard rock area boundary threshold : ; soft soil area boundary threshold : ; Transition zone: meet .
[0052] This setting has a relative adaptability, can be overall level floating with the geological stiffness distribution.
[0053] S42, geological type determination and identification matrix generation: traverse all spatial grid cells of the comprehensive geological stiffness index value matrix , execute the following type determination logic: ; 1. Output structure package: the output structure of each cell is: , where Type takes the value of hard rock area, soft soil area or transition zone.
[0054] 2. Generate identification matrix: build an identification matrix with the same G dimension as , used for spatial clustering analysis.
[0055] S43, spatial clustering processing of geological construction unit: to eliminate discrete error classification and boundary burr, improve the engineering practicability of regional division, execute the following clustering and correction operation: 1. Spatial connected domain identification: to eliminate discrete error classification and boundary burr, improve the engineering practicability of regional division, execute the following clustering and correction operation: Perform three-dimensional eight-neighborhood connected domain search on the three types in the identification matrix M; Use seed filling (floodfill) or union set algorithm to mark each connected domain.
[0056] Calculate the corresponding spatial area of each connected domain : ; Where n is the number of connected cells, (consistent with the grid size).
[0057] 2. Eliminate isolated small units: for areas with an area , it is considered to have no independent construction significance, and the correction strategy is executed, using the type of the adjacent maximum area connected block to replace the type of the current isolated block.
[0058] 3. Output spatial distribution map: encode the clustering results into a spatial type layer, output as GeoTIFF or Shapefile format, each pixel / vector unit contains attributes: spatial coordinates, type identification, area and boundary contour.
[0059] S5: assign hydraulic impact hammer units to hard rock areas, assign vibration pile sinking units to soft soil areas, and assign rotary drilling units to transition zones to form an initial equipment allocation scheme, which is: S51, hydraulic impact hammer unit quantity configuration: first, extract all grid cells marked as hard rock area from the hard rock area spatial distribution map, count the total number, multiply the cell area to get the total area of hard rock area. The unit area can be set according to the grid resolution, for example, the standard grid resolution is ten meters by ten meters, then the area of each unit is one hundred square meters.
[0060] Next, according to the unit area construction efficiency of hydraulic impact hammer unit, divide the total area of hard rock area by the daily processing capacity of a single device to determine the theoretical number of required devices. To ensure complete construction coverage, if the construction amount of less than one device is still calculated as one device, that is, rounding up.
[0061] Subsequently, according to the spatial distribution of each grid in the hard rock area, all hard rock area grids are divided into block-shaped connected regions, and the hydraulic impact hammer unit with higher number is preferentially allocated to the region with larger area. Each device is bound to the grid coordinate set it is responsible for, and the device number and working area are marked in the spatial layer.
[0062] For example, if the total area of hard rock area is sixteen thousand square meters, the system will automatically configure eleven hydraulic impact hammer units, and generate device numbers such as "HY-001" to "HY-011", which correspond to the divided construction sub-region grid list respectively.
[0063] S52, vibration pile sinking machine unit quantity configuration: the processing process of soft soil area is consistent with S51. The system reads the soft soil area spatial distribution map, accumulates the number of all grid cells marked as soft soil area, and converts it into the total construction area.
[0064] According to the daily coverable area of the vibration pile sinking machine unit, the required equipment quantity is calculated, and the actual unit quantity is configured by rounding up.
[0065] Spatial aggregation is performed on the soft soil area grid, and the vibration pile sinking machine unit number is reasonably allocated according to the area size and shape, for example, using the number prefix "ZD-", such as "ZD-001", "ZD-002", etc.
[0066] At the same time, the construction grid coordinate set responsible by each vibration pile sinking machine unit is generated, and the deployment position and service area of the device are marked in the visualization layer.
[0067] S53, rotary drilling rig unit quantity configuration: for the transition area, first count all transition area grid cells in the transition area spatial distribution map, and calculate the total area.
[0068] Because the geological characteristics of the transition area have the characteristics of soft and hard interlacing or gradual change, the construction efficiency of the rotary drilling rig unit is relatively low, so a smaller unit area construction capacity is used as the benchmark when configuring the quantity.
[0069] The number of rotary drilling rig units is divided according to the area, and the deployment area of each unit is divided according to the spatial connectivity. Each rotary drilling rig unit is assigned a unique number, such as "ZX-001", "ZX-002", etc., and is bound to the output of the grid coordinate set under its jurisdiction.
[0070] To avoid resource waste, priority is given to ensuring good geographical continuity of the areas responsible for each unit, reducing the frequency of unit movement.
[0071] S54, initial device allocation scheme generation: finally, the system will summarize the deployment information of the three types of construction equipment to form a complete initial device allocation scheme, including: Hard rock area deployment scheme: contains the total number of hydraulic impact hammer units and each unit number, corresponding construction grid coordinate set, equipment service area boundary, etc.
[0072] Soft soil area deployment scheme: contains the total number of vibration pile driving machine units and each unit number, corresponding construction grid coordinate set, equipment distribution center point position, etc.
[0073] Transition zone deployment scheme: contains the total number of rotary drilling rig units and each unit number, responsible space grid set, area shape description, etc.
[0074] Equipment dispatch list: includes the total number of hydraulic impact hammer units, vibration pile driving machine units and rotary drilling rig units, lists the number of each type of equipment, service area number, planned start time, etc. Field, forming a standard input template for construction plan and operation scheduling interface; S6: when the real-time monitoring of the comprehensive geological stiffness index of a unit changes by more than ±15%, trigger the adjacent area equipment scheduling instruction, update the dynamic resource allocation scheme, specifically: S61, geological variation unit detection and marking: continuously monitor the real-time update status of the standardized geological data cube, especially the comprehensive geological stiffness index field.
[0075] In each update period (set to daily or every 4 hours), all spatial grid units are traversed from the latest cube data, the current comprehensive geological stiffness index is extracted, and the initial value recorded in the initial device allocation scheme is compared.
[0076] When the change in the comprehensive geological stiffness index of any grid unit relative to the initial value exceeds ±15%, the system marks the grid unit as a geological variation unit.
[0077] For each geological variation unit, the system extracts its three-dimensional spatial coordinates and the changed comprehensive geological stiffness index, writes it into the geological variation log, and generates a visual highlight identification layer for the dispatch system to call.
[0078] For example, in a certain construction area, the original comprehensive geological stiffness index of grid unit G_132_57 is 0.62, and the updated value is 0.72. The determined change range is 16.1%, which meets the variation condition, and the grid is marked as a geological variation unit.
[0079] S62, adjacent area scheduling instruction generation: perform adjacent area expansion analysis on each geological variation unit, expand one grid unit in all directions above, below, left and right and diagonally from the center of the unit to form a three-by-three nine-grid adjacent area.
[0080] Subsequently, according to the index change direction of the geological variation unit, the following scheduling rules are executed: If the increase of the comprehensive geological stiffness index after the variation is ≥15%, the system determines that the regional geology is hardened, and the rotary drilling rig unit originally deployed in the adjacent area may no longer be suitable, and needs to be switched to a hydraulic impact hammer unit. The system issues a device conversion instruction and records it in the scheduling log.
[0081] If the decrease of the comprehensive geological stiffness index after the variation is ≥15%, the system determines that the regional geology is softened, and the originally deployed hydraulic impact hammer unit may be over-provisioned, and needs to be switched to a vibratory pile driver unit. The system automatically issues a corresponding device switching instruction.
[0082] If the variation range is within ±15%, the system determines that the geological state is relatively stable, and the original device can continue to work without any adjustment.
[0083] The system encapsulates each adjacent area device scheduling instruction as a structured data packet, including the geological variation unit number, the adjacent area grid coordinate set, the variation type, the target device type and the execution priority.
[0084] S63, dynamic resource allocation scheme update: according to the scheduling instructions generated in S62, the system starts the dynamic resource allocation module to modify the device deployment scheme and the device scheduling list as follows: 1. Unbind the original device binding relationship: first, find the device information bound to the current adjacent area grid in the initial device allocation scheme, unbind the device from its corresponding grid coordinate set, and mark the device as to be redeployed.
[0085] 2. Reallocate device type: according to the target device type required in the scheduling instruction, reconfigure the appropriate unit type for the adjacent area grid. Preferably, allocate the same type of device that is currently in idle or standby state; if there is no available device, then call a new device from the standby resource pool for supplementation.
[0086] 3. Update the device scheduling list: adjust the number of each type of device in the device scheduling list, record the device number, change time and scheduling source of the added or released device, and synchronize to the resource scheduling database.
[0087] 4. Generating dynamic resource deployment scheme: merging the latest equipment binding results of the mutation unit and its adjacent area into the equipment deployment master layer. The system outputs the dynamic resource deployment scheme text list and layer file containing the latest equipment number, construction grid coordinate set, equipment type and dispatch source.
[0088] For example, if the grid numbered G_75_120 has a comprehensive geological stiffness index drop of 17.8% during construction, the system detects that the original deployment is a hydraulic impact hammer unit, and under the dispatch instruction, the construction equipment in this area and its adjacent area is re-designated as a vibratory pile driver unit, and a device instance numbered ZD-021 is generated and deployed to the target area, while updating the dispatch list to record the change event.
