Description

Technical Field

[0001] The present invention relates to the technical field of pile-soil models, and in particular to an automated construction method, device, equipment and storage medium for a three-dimensional pile-soil model. Background Art

[0002] At present, 3D geological model technology is mainly used in the field of geological and mineral exploration, and the technology is relatively mature. However, in the field of pile foundation engineering, the presentation of geological survey information still mainly relies on the bar chart of a single borehole or the geological profile of multiple boreholes, which cannot intuitively display the 3D geological structure of the entire engineering site. This limitation makes it difficult for engineers to fully and accurately grasp the overall geological information of the site under complex geological conditions. Especially when the number of boreholes is limited, relying on these local geological data for design and construction decisions often brings greater uncertainty and risk. In addition, the existing 3D geological model construction technology is mostly static and cannot be dynamically updated according to real-time data during the construction process, which seriously limits its practical application value in pile foundation engineering.

[0047] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] In order to solve the problems in the prior art, the present invention proposes an automated construction method for a three-dimensional pile-soil model to achieve rapid modeling of the pile-soil model. The automated construction method for the three-dimensional pile-soil model is described below. Figure 1 As shown, including but not limited to the following steps:

[0049] Step 110: Acquire the data to be modeled, wherein the data to be modeled includes drilling attribute data and pile position design data.

[0050] In this step, the data to be modeled are first obtained, and the data to be modeled include borehole attribute data and pile position design data. Borehole attribute data refers to the physical, chemical and geological property information of the soil obtained through borehole measurement, such as soil type, density, porosity, compressive strength, etc. The pile position design data includes the specific location, depth, number and other design parameters of the pile. These data can be obtained through geological exploration, field measurement or database query, and stored in a computer system in a standard format for subsequent processing.

[0051] The borehole location, borehole properties, and pile location design data are required in the modeling stage. The standardized formats are shown in Tables 1, 2, and 3.

[0058]

[0059] Step 120: number all strata revealed by the boreholes in the target modeling area according to the sequence of strata deposition and based on the borehole attribute data to obtain a borehole stratigraphic sequence.

[0060] In this step, based on the borehole attribute data obtained in step 110, the strata revealed by all the boreholes in the target modeling area are numbered according to the sequence of strata deposition. The specific operation is as follows:

[0061] Identify stratigraphic information for each drill hole, including the depth range and attribute characteristics of each formation.

[0062] According to the sequence of stratigraphic deposition, the strata are sorted from the bottom to the top to form a drilled stratigraphic sequence.

[0063] Assign each stratum a unique number to facilitate subsequent reference and processing.

[0064] The result of this step is an ordered list containing all the drilled stratigraphic information, which is convenient for subsequent data interpolation and 3D modeling.

[0065] Step 130: Perform inverse distance weighted interpolation based on the drilled stratigraphic sequence and the pile position design data to determine a pile position stratigraphic data set at the pile position.

[0066] In step 130, based on the drilled stratigraphic sequence generated in step 120, inverse distance weighted interpolation is performed to determine the pile stratigraphic data set at the pile position. The specific process is as follows: determine the target pile position for interpolation, and identify the pile position that needs to be interpolated based on the pile position design data. For each target pile position, calculate its distance from all boreholes, and assign weights according to the size of the distance. The closer the distance, the greater the weight of the borehole. Using the inverse distance weighted method, the stratigraphic data of each borehole is weighted averaged according to the weight, and finally the stratigraphic data set at the pile position is obtained. Ensure that the interpolation result covers all relevant stratigraphic information of the target pile position and forms a structured data set.

[0067] Step 140: Perform three-dimensional modeling based on the pile position stratum data set to obtain a target pile-soil model.

[0068] In step 140, three-dimensional modeling is performed based on the pile position stratum data set obtained in step 130 to obtain a target pile-soil model. Specifically, a three-dimensional modeling software is used to input the pile position stratum data set into a modeling system. Through a modeling tool, a three-dimensional borehole model, a layer model, and a solid model are drawn based on the stratum data. The model is visualized so as to intuitively display the stratum structure and pile position distribution. The target pile-soil model finally generated can be used for subsequent geological analysis, engineering design, and decision support.

[0069] As a further optional embodiment, the borehole stratigraphic sequence includes: a borehole macrostratum sequence and a borehole substratum sequence, and the step of numbering all strata revealed by the boreholes in the target modeling area according to the stratigraphic deposition order and based on the borehole attribute data to obtain the borehole stratigraphic sequence specifically includes:

[0070] According to the stratigraphic deposition sequence and based on the borehole attribute data, all the stratigraphic layers revealed by the boreholes in the target modeling area are numbered to obtain a borehole macrostratum sequence;

[0071] Based on the large-layer sequence of drill holes, construct a drill hole plane triangulation network;

[0072] The drilling sublayer sequence is determined based on the drilling plane triangulation network.

[0073] In this embodiment, the strata revealed by all the boreholes in the target modeling area are numbered according to the order of strata deposition and according to the borehole attribute data to form a borehole stratigraphic sequence. Specifically, the attribute data of each borehole in the target modeling area, including depth, soil type, physical properties, etc., are collected. Then, the strata revealed in each borehole are sorted according to the order of strata deposition. All strata are numbered from the bottom to the top to form a borehole large layer sequence. The number of each large layer should reflect its relative position in the deposition sequence and contain corresponding attribute information, such as thickness and material properties. Subsequently, based on the borehole large layer sequence, a borehole plane triangulation network is constructed using a three-dimensional modeling software. The grid can effectively connect the borehole position and its large layer sequence to form a two-dimensional plane model for subsequent processing and analysis. During the construction process, it is necessary to ensure that all boreholes and their corresponding large layer sequences can be accurately represented in the plane grid. Finally, according to the borehole plane triangulation network, the details inside each large layer are further analyzed to identify and number the borehole sublayers. Sublayers are different soil layers that exist within the same large layer and may have different characteristics and properties. The process of determining sublayers involves extracting information from the planar triangulation network, identifying the depth range of each sublayer and its characteristics, and numbering them to form a complete sequence of drill hole sublayers.

[0074] Through the above steps, the generated drilled stratigraphic sequence will include detailed drilled macro-layer sequences and sub-layer sequences, thereby providing more detailed and accurate stratigraphic information for subsequent data interpolation and three-dimensional modeling. This embodiment significantly improves the accuracy and reliability of modeling and is suitable for various application scenarios such as geological exploration and engineering design.

[0075] As a further optional embodiment, the borehole large layer sequence includes a borehole real layer sequence and a borehole virtual layer sequence, and the step of numbering all the strata revealed by the boreholes in the target modeling area according to the stratum deposition order and according to the borehole attribute data to obtain the borehole large layer sequence specifically includes:

[0076] According to the stratigraphic deposition sequence and based on the borehole attribute data, all the stratigraphic layers revealed by the boreholes in the target modeling area are numbered to obtain a borehole macrostratum sequence;

[0077] The strata missing from the boreholes in the target modeling area are numbered to obtain a virtual layer sequence of the boreholes.

[0078] like Figure 2 As shown, in this embodiment, the strata revealed by all the boreholes in the target modeling area are numbered according to the sequence of strata deposition and combined with the borehole attribute data to form a large sequence of borehole layers. Specifically: the attribute data of each borehole in the target modeling area, including soil type, depth, physical and chemical properties, etc., are collected to facilitate subsequent analysis. In all boreholes, the actual strata revealed are sorted and numbered according to the sequence of strata deposition. The actual layer refers to the stratum actually observed in the borehole, and the numbering should reflect its position and attributes in the deposition sequence. The thickness, type and other important attributes of each actual layer are recorded to ensure the accuracy of subsequent modeling.

[0079] If a large layer is missing in the borehole, a virtual layer can be inserted at its corresponding position to ensure the uniformity of the stratigraphic information. Analyze the boreholes in the target modeling area to identify those strata that are not observed in the actual boreholes but may exist based on the stratigraphic depositional laws or stratigraphic characteristics of adjacent boreholes. Generate numbers for these missing strata to form a borehole virtual layer sequence. The virtual layer sequence should be reasonably inferred based on the real layer data and depositional laws of adjacent boreholes, and include the estimated properties of each virtual layer.

[0080] The generated real and virtual layers of the boreholes are integrated to form a complete large-scale sequence of borehole layers, which can provide comprehensive stratigraphic information, including both the actually observed layers and the inferred layers.

[0081] like Figure 2As shown in the figure, the stratigraphic layers of boreholes SG09, SG10, and SG17 are numbered from top to bottom as ['1', '2', '3', '4', '5', '6']. The numbers of their sublayers start with the number of the large layer, such as ['4-1', '4-2-a'] are all sublayers of large layer No. 4. The blue triangle in the figure (not reflected in the figure) indicates that in order to unify the large layers of all boreholes, a virtual layer 0 is automatically inserted at the corresponding position. The automatically inserted virtual layer number ends with '-0' to distinguish them. For example, a virtual layer 1-0 is inserted at the top of large layer No. 2 in borehole SG09, virtual layers 2-0, 4-1-0, and 5-0 are inserted at the top and bottom of large layer No. 3 in borehole SG10, and virtual layers 2-0 and 5-0 are inserted at the bottom of large layers No. 1 and No. 4 in borehole SG17, respectively.

[0082] Through the above steps, the generated large-scale sequence of drill holes can fully reflect the stratigraphic characteristics of the target modeling area and enhance the accuracy and reliability of modeling. This refined method is particularly suitable for exploration and modeling work in complex geological environments, and helps to improve the effectiveness and safety of engineering design.

[0083] As a further optional embodiment, the drilling sub-layer sequence includes a drilling real sub-layer sequence and a drilling virtual sub-layer sequence, and the step of determining the drilling sub-layer sequence according to the drilling plane triangulation specifically includes:

[0084] Determine the starting triangular unit in the current drilling plane triangulation network;

[0085] Based on the starting triangular unit, extract and unify sublayer information to obtain a drilling sublayer sequence;

[0086] The sublayers missing from the boreholes in the target modeling area are numbered to obtain a drill hole virtual layer sequence.

[0087] refer to Figure 3 In this embodiment, it is necessary to determine the borehole sublayer sequence based on the borehole plane triangulation network. Specifically, in the constructed borehole plane triangulation network, an appropriate starting triangular unit is selected. This unit is usually located at a key position of stratigraphic change, such as an area with significant geological features or layer boundaries, to ensure that the extracted information can represent the characteristics of the entire modeling area. Preferably, the triangle with the least number of shared vertices can be selected as the starting triangular unit. Then, based on the selected starting triangular unit, gradual expansion and information extraction are performed. The sublayer information of each borehole in the current triangular unit and its adjacent units is extracted, including the type, thickness and characteristics of the sublayer. The extracted sublayer information is unified and organized to ensure that sublayers of the same type have consistent naming and numbering rules between different boreholes. This process ensures the integrity and consistency of the data, facilitating subsequent modeling and analysis.

[0088] Subsequently, the boreholes in the target modeling area are analyzed to identify those sublayers that are not observed in the actual boreholes but may exist. These missing sublayers can be reasonably inferred based on the existing borehole data, geological laws and sedimentary patterns. Numbers are generated for these missing sublayers to form a borehole virtual sublayer sequence. This sequence should take into account the actual sublayer information and sedimentary environment of adjacent boreholes to ensure the accuracy and scientificity of the inference.

[0089] Through the above steps, the generated borehole sublayer sequence not only contains the sublayer information actually observed, but also includes the virtual sublayer information inferred according to geological laws, which fully reflects the geological characteristics of the target modeling area. This refined sequence construction method helps to improve the accuracy and reliability of the 3D pile-soil model, and is particularly suitable for engineering exploration and design under complex geological conditions.

[0090] refer to Figure 3 , taking SG10, SG11, and SG18 as examples, the sublayer sequence of the No. 3 large layer is unified. The first layer of SG10, SG11, and SG18 is the 3-1-a stratum, so the No. 1 sublayer of the No. 3 large layer is unified as 3-1-a. Processing the next layer, the second layer of SG11 and SG18 is 3-1-b, while SG10 does not have a second layer, so the No. 2 sublayer of the No. 3 large layer is unified as 3-1-b, and the 3-1-b-0 virtual layer is inserted at the bottom of the No. 1 sublayer of SG10 as its No. 2 sublayer. Continue to process the next layer, the third layer of SG11 is 3-1-a, while the other two boreholes do not have a third layer, so the No. 3 sublayer of the No. 3 large layer is unified as 3-1-a, and 3-1-a-0 is inserted at the bottom of the No. 2 sublayer of SG10 and SG18 as its No. 3 sublayer. When the stratigraphic sequences of the No. 3 layers of the three boreholes are completely consistent, it is considered that the stratigraphic sequence of the No. 3 layer of the current triangular unit is unified. Repeat the above steps to process other layers until all stratigraphic sequences of the three boreholes are unified, and record the stratigraphic sequence as the unified stratigraphic sequence ['1', '2', '3-1-a', '3-1-b', '3-1-a', '4', '5', '6-1-a', '6-1-b', '6-2'].

[0091] As a further optional embodiment, the step of extracting and unifying sub-layer information based on the starting triangular unit to obtain a drilling sub-layer sequence specifically includes:

[0092] The sub-layer information corresponding to each borehole in the starting triangular unit is extracted, and the sub-layer information is arranged according to a preset stratigraphic order.

[0093] In this embodiment, in the selected starting triangular unit, each borehole adjacent to it is analyzed one by one. For each borehole, the corresponding sublayer information is extracted, including the type, thickness, physical and chemical properties of each sublayer. During the extraction process, the information obtained from different boreholes is ensured to be consistent to avoid inaccurate information due to differences in measurement methods or data recording.

[0094] Subsequently, the extracted sublayer information is arranged in a preset stratigraphic order. The order should be based on geological characteristics and sedimentary processes, for example, from surface to bottom, from new to old, etc. During the arrangement process, it is ensured that sublayers of the same type can be compared in different boreholes and their relative positions remain stable. This process helps to further understand the stratigraphic relationship and evolution process of the strata.

[0095] Through the above steps, the final drill hole sub-layer sequence will provide detailed and consistent geological information for subsequent 3D modeling. This unified sub-layer information processing method not only improves the availability of data, but also provides a solid foundation for engineering applications in complex geological environments, ensuring the scientificity and accuracy of the model.

[0096] As a further optional embodiment, the step of performing inverse distance weighted interpolation according to the drilled stratum sequence and the pile position design data to determine the pile position stratum data set at the pile position specifically includes:

[0097] Determining an interpolated target pile position according to the pile position design data;

[0098] Inverse distance weighted interpolation is performed on the target pile position to determine a pile position stratigraphic data set at the pile position.

[0099] In this embodiment, it is necessary to perform inverse distance weighted interpolation based on the borehole stratigraphic sequence and the pile position design data to determine the pile position stratigraphic data set at the pile position. Specifically, the information of each target pile position is extracted from the pile position design data, including its coordinate position, design depth and other relevant geological information. According to the extracted pile position information, the target pile position to be interpolated is determined. These target pile positions are the basis for subsequent interpolation calculations. Then, for each target pile position, the distance between it and all known boreholes is calculated. The distance can be measured using Euclidean distance or other appropriate measurement methods. According to the distance information, the stratigraphic data of each borehole is weightedly calculated using the inverse distance weighted interpolation formula. Specifically, the closer the borehole is, the greater the weight of its stratigraphic data in the interpolation, and vice versa. After the inverse distance weighted interpolation calculation, the pile position stratigraphic data set of the target pile position is obtained. The data set contains the geological characteristics of each layer related to the target pile position, such as soil layer type, thickness and its physical and chemical properties.

[0100] Through the above steps, the pile position stratigraphic data set finally generated provides accurate geological information for subsequent 3D modeling, ensuring the scientificity and practicality of model construction. This method not only improves data utilization efficiency, but also provides important support for engineering design in complex geological environments.

[0101] As a further optional embodiment, the step of performing three-dimensional modeling according to the pile position stratum data set to obtain a target pile-soil model specifically includes:

[0102] The pile position stratum data set is visualized by a three-dimensional visualization toolkit, including a three-dimensional drilling model of a target pile-soil model, a three-dimensional layer model and a three-dimensional solid model.

[0103] In this embodiment, it is necessary to perform three-dimensional modeling based on the pile position stratigraphic data set to obtain the target pile-soil model. Specifically, it is ensured that the obtained pile position stratigraphic data set contains complete stratigraphic information, including the thickness of each layer, soil type and its physical and chemical properties, etc. A suitable three-dimensional visualization toolkit is selected, which supports three-dimensional visualization and modeling functions of geological data and can process complex stratigraphic data.

[0104] Next, refer to Figure 4 , based on the drilling information in the pile position stratigraphic dataset, a 3D drilling model of each target pile position is constructed, and different soil layers can be distinguished by different colors (not shown in the figure). This model shows the depth of the drilling hole, the stratigraphic distribution and the properties of each layer, making it intuitive to display the underground structure.

[0105] refer to Figure 5 In 3D space, a 3D layer model is generated based on the depth and thickness information of each layer in the borehole model. This model shows the distribution and contact relationship of different soil layers, which helps to understand the overall layout of the geological structure, and different soil layers can be distinguished by different colors (not shown in the figure).

[0106] refer to Figure 6 Based on the 3D layer model, an overall 3D solid model is constructed. This model presents each layer in a solid form, and different soil layers can be distinguished by different colors (not shown in the figure), which is convenient for in-depth geological analysis and engineering applications.
