[0022] Example 1 See also Figure 1 , an embodiment provided by the present invention: a water conservancy project construction management method based on three-dimensional visualization, comprising the following specific steps: Step S1: collecting relevant data of the water conservancy project construction area and performing preprocessing to obtain first monitoring data; Relevant data for water conservancy project construction areas include: geological exploration data, which obtains detailed information on underground structures through drilling, geophysical exploration, seismic wave reflection data, etc. These data are mainly used to identify geological characteristics such as soil bearing capacity and groundwater level in different areas; Remote sensing and laser radar (LiDAR) data, using drone aerial photography, satellite remote sensing or ground-based laser radar scanning to obtain high-precision terrain data of the construction area. LiDAR technology can provide high-resolution 3D point cloud data, which is essential for building accurate 3D models; Meteorological and environmental data, including precipitation, temperature and humidity, wind speed, climate change, etc. Real-time meteorological data is crucial, especially in the process of soil and water conservation and ecological monitoring in the construction area; Construction data, including construction progress, equipment location, construction personnel distribution, etc., to ensure that all data can be updated synchronously with the actual construction process; and related historical data.

[0023] The preprocessing includes: data cleaning, cleaning the collected data related to the water conservancy project construction area to eliminate noise data and abnormal values; standardization processing, converting data from different sources and in different formats into a unified data format to facilitate subsequent analysis.

[0024] Step S2: constructing a three-dimensional digital model of the water conservancy project based on the first monitoring data; The specific steps of step S2 are: Step S201: constructing a first model, a second model, a third model and a fourth model of a water conservancy project according to the first monitoring data; In this embodiment, the first model may be: a terrain and geological model, using a point cloud of laser radar (LiDAR) scanning data to fit the ground surface through a weighted least squares algorithm to obtain a point cloud set of a three-dimensional terrain model, and converting the point cloud set data of the three-dimensional terrain model into a visual terrain map using a triangular mesh (TIN) or a contour method; The second model can be: underground structure model. According to geological exploration data, the finite element analysis method is used to model the underground structure (such as soil layer, rock layer, etc.) to evaluate its bearing capacity and stability. By introducing boundary conditions and load effects in the model, the mechanical response of soil layers at different depths is analyzed. The specific formula of the underground structure model is: ,in, represents the stress tensor at coordinate (i, j), and represents the Lamé constant, represents the Kronecker symbol, represents the strain tensor at coordinate (i, j), The trace of strain, i.e. the total amount of strain, is used to simulate the response of different geological layers under different loads through finite element analysis to determine the areas where problems are most likely to occur; The third model can be: environmental and hydrological model, which uses meteorological data and hydrological data to build a hydrological environment model to evaluate soil erosion and ecological impact during the construction process, and uses the USLE soil erosion model, combined with terrain and precipitation data, to predict the intensity of soil erosion in different areas, and combines it with a three-dimensional terrain model to show the vulnerable areas; The fourth model may be: a construction model, which includes construction progress, equipment location, construction quality data, etc., and is established through dynamic geometry updating and timing analysis.

[0025] Step S202: determine a unified spatial reference system, and convert the coordinate systems of each model to the selected spatial reference system through a coordinate conversion algorithm; In this embodiment, different models may be constructed based on different coordinate systems. For example, the first model uses a local engineering coordinate system with a fixed point of the dam as the origin; the second model is based on the national geodetic coordinate system for large-scale terrain matching; the coordinate system of the third model is a relative coordinate system based on CAD drawings; the fourth model uses a custom coordinate system based on the installation location of the monitoring equipment, etc. Using known control point information, such as geodetic control points and engineering benchmark points, a seven-parameter or four-parameter transformation model is used to transform the point coordinates in each model. For example, for the first model using the local engineering coordinate system, the transformation parameters are calculated based on the correspondence with the known control points in the national geodetic coordinate system to achieve the transformation of the model coordinates to the national geodetic coordinate system, ensuring that all models can be accurately matched in the same spatial framework. Step S203: using the actual geographical location and logical structure relationship of the water conservancy project, the first model, the second model, the third model and the fourth model of the water conservancy project are integrated to construct a three-dimensional digital model of the water conservancy project.

[0026] In this embodiment, the surface is used as the interface, and the geological model is embedded into the corresponding position below the terrain model by matching the terrain undulation data with the underground geological stratification data. The Boolean operation function of the three-dimensional modeling software is used to ensure that the two fit seamlessly, so that the geological structure changes can transition naturally with the terrain undulations. For the structure of the water conservancy facilities, it is accurately placed on the terrain model according to the design and planning position, and according to the coordinate positioning information of the construction drawings, the transformation operations such as translation, rotation, and scaling are used to make it adapt to the terrain and geological models. For example, the dam model is accurately located on the riverbed, and the foundation part is consistent with the dam foundation rock layer in the geological model. The real-time data during the construction process (such as construction progress, equipment location, construction quality data, etc.) is directly embedded in the three-dimensional model. For the environment, according to the spatial correlation between its monitoring range and the water conservancy project area, the environmental elements representing vegetation coverage, water ecology, etc. are integrated into the overall model in the form of layer overlay, and reasonable transparency and display priority are set, so that the ecological environment information can be presented intuitively without hindering the viewing of the main structure of the water conservancy project and the terrain and geology.

[0027] Step S3: Based on the three-dimensional digital model of the water conservancy project and in combination with the historical construction data of the water conservancy project, the construction risk of the water conservancy project is evaluated; The specific steps of step S3 are: Step S301: Analyze the impact of geological bearing capacity on the dam body of the water conservancy project based on the three-dimensional digital model of the water conservancy project; Step S302: Analyze the influence of groundwater seepage, soil compressibility, and underground structure on the dam of the water conservancy project; Step S303: Simulate the hydrology and meteorology of the reservoir and analyze the impact of water level changes on the dam of the water conservancy project; Step S304: During the construction process, the additional load on the dam body and foundation soil layer is generated by combining the construction history data and the real-time data analysis to obtain the impact of the construction process on the dam body of the water conservancy project; In this embodiment, factors such as vibration, load application, and settlement during the construction process also affect the ultimate bearing capacity of the dam body. Before the reservoir is filled with water, the construction process may cause settlement or compression of the local foundation; Impact of loads during construction: During the construction process, the operation of equipment, material stacking and construction technology may generate additional loads on the dam body and the foundation soil layer, thereby affecting the stability of the dam body; Construction vibration and dam body stability: The impact of vibrations that may occur during the construction process on the dam body also needs to be dynamically analyzed. Based on the construction vibration data, a dynamic model can be used to analyze the vibration impact on the dam body during construction, so as to further predict the long-term stability of the dam body.

[0028] Step S305: By dynamically analyzing and weighted coupling geological influences, underground structure influences, hydrological and meteorological influences, and construction influences, an assessment value of the water conservancy project construction risk is obtained.

[0029] In this embodiment, the dynamic analysis and coupling methods can be used to evaluate the construction risks of water conservancy projects in a relatively comprehensive and real-time manner, providing a scientific basis and decision-making support for risk management during the construction process.

[0030] The specific steps of step S301 are: Step S3011: Based on the three-dimensional digital model of the water conservancy project, the stability of the dam body is simulated using the stress-strain relationship. The specific formula is: , Among them, Yl represents stress, P represents force, and A represents contact area; In this embodiment, calculations are performed on each local area of ​​the dam foundation to ensure that the stress in each area of ​​the dam is within the bearing range during the reservoir impoundment process. Step S3012: For different soil layers and rock layers, the maximum bearing capacity of the soil layer and / or rock layer is calculated. The specific formula is: , in, Indicates the maximum bearing capacity of the soil layer and / or rock layer. represents the coefficient related to soil type, represents the compressive strength of soil, z represents the underground depth, and H represents the total thickness of the soil layer and / or rock layer; Step S3013: Combined with finite element analysis, the stress distribution of the dam body and foundation soil layer under different water storage conditions is calculated, and the bearing capacity of the dam body is further obtained.

[0031] The specific steps of step S302 are: Step S3021: During the construction of the dam, the change in groundwater level will affect the stability of the dam. The influence on the stability of the dam is analyzed, including: buoyancy, seepage pressure and water pressure difference. In this embodiment, the buoyancy effect: the groundwater below the dam foundation will generate buoyancy on the dam body, and the buoyancy is equal to the weight of the groundwater displaced by the dam body. The buoyancy will reduce the effective pressure between the dam body and the foundation, thereby reducing the anti-sliding stability of the dam body; the seepage pressure effect, when the groundwater infiltrates the dam foundation and the dam body, it will generate seepage pressure, which will form a seepage field inside the dam body, generating a horizontal thrust on the dam body. At the same time, the seepage pressure may also lead to the loss of soil particles inside the dam body, causing seepage damage such as pipe bursts, further affecting the stability of the dam body; the water pressure difference effect, the groundwater pressure difference above and below the dam foundation will generate an upward supporting force on the dam body; in summary, the change in groundwater level has many adverse effects on the stability of the dam body by generating buoyancy, seepage pressure and water pressure difference.

[0032] Step S3022: Analyze the influence of groundwater level change on the settlement of underground soil layer and / or rock layer. The specific formula is: , in, Indicates the settlement of underground soil layer and / or rock layer, represents the load, E represents the elastic modulus of the soil layer and / or rock layer, Indicates the load area.

[0033] By simulating the settlement process after water storage, the stability of the dam can be evaluated.

[0034] The specific steps of step S303 are: Step S3031: Estimate the water storage capacity of the reservoir based on hydrological and basin precipitation data. The specific formula is: , in, represents the reservoir water storage at time t, represents the reservoir water storage at time t-1, Indicates the amount of water coming in. Indicates the amount of water discharged. Indicates evaporation; Step S3032: Calculate the buoyancy generated by the water level change and analyze the influence of the buoyancy effect generated by the water level change on the dam body. The specific formula of buoyancy is: , in, Indicates the buoyancy caused by water level changes, represents the density of water, represents the volume displaced by water and g represents the acceleration due to gravity.

[0035] In this embodiment, the influence of the buoyancy on the dam body is calculated by combining the finite element method to evaluate the safety of the dam body stability during water level changes.

[0036] Step S4: Based on the risk assessment, risk levels are classified and water conservancy project construction is dynamically managed.

[0037] The risk level classification includes: different risk levels are classified according to the calculated risk assessment value, risk assessment value <0.3 is low risk, 0.3≤risk assessment value≤0.6 is medium risk, and risk assessment value >0.6 is high risk. When the construction risk assessment value reaches medium risk or above, an early warning signal is issued to remind construction management personnel to take corresponding risk response measures. For example, for high-risk situations, it may be necessary to suspend construction, conduct detailed inspections and reinforcements on geology and underground structures, strengthen hydrological and meteorological monitoring, optimize construction technology and quality control, etc.; for medium-risk situations, measures such as increasing the monitoring frequency and partially adjusting the construction plan can be taken.
