Description

Technical Field

[0001] This invention relates to the field of pile-soil stress analysis technology, and specifically to a pile-soil stress analysis system. Background Technology

[0002] With the increasing development of marine resources and the growing number of marine engineering projects in my country, pile foundation engineering plays a crucial role in marine engineering structures. Pile-soil stress analysis is one of the core technologies in pile foundation engineering design, directly affecting the safety, stability, and economy of the project. In various marine environments, pile-soil stress analysis under complex wave conditions is particularly critical and complex.

[0003] In related technologies, pile-soil stress analysis primarily relies on static methods. These static methods typically assume the load is static, neglecting time-varying and dynamic effects. Instead, they assess the stress on the pile foundation by calculating the stress and displacement under static loads. This approach can predict pile foundation stress relatively well under calm water conditions. However, in actual marine environments, waves are a major dynamic factor. Complex waves, such as nonlinear waves, wave-current interactions, and wave breaking, can significantly impact the stress on pile foundations. Therefore, static analysis methods cannot accurately capture dynamic changes under complex wave conditions, leading to significant limitations in predicting pile-soil stress under such conditions. Summary of the Invention

The data acquisition module, as the starting point of the pile-soil action stress analysis system, bears the important responsibility of accurately collecting and inputting various key parameters. This data acquisition module ensures data accuracy and efficiency through the following methods.

[0057] The pile-soil stress analysis system in this embodiment also has data backup and recovery functions to ensure data security and accuracy.

[0058] The data simulation module is used to construct a three-dimensional pile-soil model based on wave parameters, pile parameters, and soil parameters. It also uses pile-soil stress analysis to convert wave parameters into dynamic loads that are applied to the three-dimensional pile-soil model to simulate the dynamic impact of waves on the pile and obtain the stress-strain relationship of the pile and the interaction between the pile and the soil.

[0059] The data simulation module is used to construct a three-dimensional pile-soil model based on wave parameters, pile parameters, and soil parameters. It also uses pile-soil stress analysis to convert wave parameters into dynamic loads that are applied to the three-dimensional pile-soil model to simulate the dynamic impact of waves on the pile and obtain the stress-strain relationship of the pile and the interaction between the pile and the soil.

[0060] In a specific example, in Figure 2 In the middle, the data simulation module 12 includes: pile-soil model construction unit 121, wave load simulation unit 122, and pile-soil nonlinear contact unit 123.

[0061] The system includes several elements: a pile-soil model construction unit, used to construct a three-dimensional pile-soil model based on wave parameters, pile parameters, and soil parameters using the constitutive finite element method; a wave load simulation unit, used to dynamically load the three-dimensional pile-soil model based on wave parameters using potential flow theory rules, random wave spectra, or explicit dynamic algorithms to simulate the dynamic impact of waves on the pile and obtain the stress-strain relationship of the pile; and a pile-soil nonlinear contact unit, used to simulate pile-soil frictional contact based on the dynamic impact of waves on the pile and soil parameters using the penalty function method to obtain the interaction between the pile and soil.

[0062] For example, in this embodiment, the data simulation module establishes a three-dimensional pile-soil model of wave-pile-soil interaction based on wave parameters, pile parameters, and soil parameters collected by the data acquisition module, using the soil constitutive finite element method. This embodiment uses potential flow theory or wave spectrum and other pile-soil stress analysis methods to convert the collected wave parameters such as wave height, wavelength, and wave period into dynamic loads, which are then applied to the three-dimensional pile-soil model to accurately simulate the dynamic impact of waves on the pile. Then, based on the collected soil parameters such as soil density, soil elastic modulus, soil Poisson's ratio, soil type, soil internal friction angle, and soil cohesion, soil constitutive models such as the modified Cambridge model and the Drucker-Prager criterion model are selected to describe the stress-strain relationship of the pile. Furthermore, considering the nonlinearity of contact between the pile and soil, a frictional contact model or an adhesive contact model is used to simulate the interaction between the pile and soil.

[0063] In this embodiment, the data simulation module employs parallel computing to process the pile-soil 3D model, improving calculation speed and efficiency. Through this method, the data simulation module can accurately simulate the dynamic impact of wave loads on the pile and the interaction between the pile and soil, generating a pile-soil 3D model.

[0064] The data analysis module is used to analyze the stress distribution of the pile based on the stress-strain relationship of the soil using stress analysis algorithms, and to analyze the variation of pile displacement with wave period based on the interaction between the pile and the soil. It also uses pore water pressure analysis to simulate the variation of pore water pressure in the soil under different wave conditions, and then compares the simulation results under different wave parameters, pile parameters, and soil parameters. Finally, it uses sensitivity analysis algorithms to evaluate the degree of influence of different wave parameters, pile parameters, and soil parameters on the pile-soil interaction.

[0065] In a specific example, in Figure 2 The data analysis module includes: pile stress analysis unit 131, pile displacement analysis unit 132, soil pressure analysis unit 133, and parameter comprehensive analysis unit 134.

[0066] The pile stress analysis unit is used to analyze the stress distribution law of the pile based on the stress-strain relationship and stress analysis algorithm, and draw stress distribution diagram based on the stress distribution law.

[0067] For example, in this embodiment, the pile stress analysis unit performs detailed stress analysis based on the stress-strain relationship of the pile and uses stress analysis algorithms to identify high stress areas and stress concentration points, comprehensively assess the stress state of the pile and surrounding soil under wave load, with an accuracy of ±5%, providing users with accurate stress distribution information.

[0068] The pile displacement analysis unit is used to analyze the variation law of pile displacement with wave period based on the interaction between pile and soil, and to draw the frequency spectrum analysis diagram of displacement over time.

[0069] For example, the pile displacement analysis unit calculates the pile displacement based on the interaction between the pile and the soil. This displacement ranges from mm to cm with an accuracy of ±0.01 mm, and analyzes its variation with the wave cycle. By introducing a more accurate displacement calculation algorithm, the system in this embodiment can more accurately reflect the displacement changes of the pile under wave loads.

[0070] The soil pressure analysis unit is used to simulate the variation of soil pore water pressure under different wave conditions using the pore water pressure analysis calculation method, and to plot the pressure dissipation rate curve.

[0071] For example, the soil pressure analysis unit in this embodiment records the changes in pore water pressure, uses the pore water pressure analysis calculation method to simulate the changes in soil pore water pressure under different wave conditions, and plots the pressure dissipation rate curve.

[0072] The parameter comprehensive analysis unit is used to compare simulation results under different wave parameters, pile parameters, and soil parameters, and uses sensitivity analysis algorithms to evaluate the degree of influence of different wave parameters, pile parameters, and soil parameters on pile-soil interaction.

[0073] This embodiment compares simulation results under different wave parameters, pile parameters, and soil parameters, and uses a sensitivity analysis algorithm to evaluate the degree of influence of these parameters on pile-soil interaction. Therefore, this embodiment, through its parameter comprehensive analysis unit, can provide users with in-depth and comprehensive stress characteristic analysis, helping to optimize pile foundation design and construction processes.

[0074] The data display module is used to display the stress distribution law of the pile, the variation law of pile displacement with wave period, the variation law of soil pore water pressure under different wave conditions, and the degree of influence of different wave parameters, pile parameters and soil parameters on pile-soil interaction.

Furthermore, by optimizing the rendering algorithm, this embodiment improves rendering speed by 25% compared to traditional methods, providing users with a smoother and more realistic visualization experience.

[0078] In a specific example, the animation display unit is used to generate an animation of the pile-soil interaction forces in the target area based on the pile-soil interaction force rendering diagram.

[0079] This embodiment combines the pile-soil interaction stress rendering diagram of the target area generated by the image rendering unit described above, and further uses animation to intuitively display the pile-soil interaction stress animation of the target area.

[0080] In a specific example, the report output unit is used to output the pile-soil interaction force animation in the target area based on the stress distribution law of the soil, the variation law of pile displacement with wave period, the variation law of soil pore water pressure under different wave conditions, and the degree of influence of different wave parameters, pile parameters and soil parameters on pile-soil interaction.

[0081] This embodiment automatically generates detailed reports and charts through the report output unit, including stress distribution diagrams, displacement change curves, and pore water pressure change curves. Users can export reports and charts as needed, providing a scientific basis for subsequent analysis and evaluation. By introducing richer report generation functions, the system in this embodiment can provide users with a more comprehensive and convenient way to output data.

This simulates the dynamic impact of waves on the pile, obtaining the stress-strain relationship of the soil. It can accurately simulate wave loads in complex wave environments, improving simulation accuracy by 20% compared to traditional methods. Furthermore, the system incorporates a real-time verification function, automatically detecting the rationality and accuracy of wave parameters to ensure the reliability of the simulation results. Therefore, the pile-soil stress analysis system in this embodiment not only improves simulation accuracy but also significantly shortens simulation preparation time, providing users with a more efficient and accurate wave load simulation service.

[0083] Furthermore, the pile-soil stress analysis system in this embodiment supports soil constitutive models such as the modified Cambridge model and the Drucker-Prager criterion model, enabling a more realistic description of the stress-strain relationship in soil. Therefore, by introducing efficient algorithms and optimization methods, this embodiment can complete large-scale numerical simulations in a short time, improving simulation accuracy by 15%.

Therefore, the system in this embodiment can more accurately reflect the pile-soil interaction mechanism, improving simulation accuracy by 10%. Thus, this embodiment provides users with a more in-depth and comprehensive pile-soil interaction analysis service.
