Artificial fish shelter structure optimizing method

Abstract

The invention relates to an artificial fish shelter structure optimizing method, which comprises: (1) determining the shape, wall thickness and pore layout and shape of an artificial fish shelter body structure; (2) analyzing a finished artificial fish shelter body; (3) obtaining the results of the stability, flow field effect and manufacturing cost of an artificial fish shelter by analysis, and returning to the step (1) to improve the artificial fish shelter body structure if a certain data excess a threshold value according to the sea conditions and project requirements of a placing sea area; and (4) if the values obtained by the step (3) meet requirements, finishing the final design of the artificial fish shelter body, forming a construction scheme and recording analysis results. The method disclosed by the invention replaces the conventional method for performing theoretical calculation by using experience values, improves accuracy of stability analysis, provides an optimal design scheme on the basis of comprehensive stability, flow field effect and manufacturing cost factors, facilitates the summarization of structure design experience of design personnel, and summarizes the regulations and standards for making optimal design.

Description

technical field [0001] The invention belongs to the technical field of fishery infrastructure, in particular to an artificial fish reef structure optimization design method. Background technique [0002] Artificial fish reefs are structures artificially set up in waters to improve the habitat of aquatic organisms, provide places for feeding, breeding, growth, and development of marine economic organisms, and achieve the purpose of protecting and multiplying fishery resources and improving the quality of fish catches. Purpose. Under the situation of rapid population growth, decline of marine fishery resources, and environmental deterioration, the construction of artificial reefs, as a comprehensive measure for the proliferation and protection of fishery resources, has played a very good role in the restoration of the offshore ecological environment and the proliferation of fishery resources. [0003] The physical complexity of artificial reefs will have a decisive impact on ...

AI Technical Summary

Problems solved by technology

[0005] At present, the structural design of artificial reefs mainly depends on the qualitative analysis of designers based on experience. When performing stability analysis and selecting the maximum static friction coefficient and reef resistance coefficient between reefs and seabed sediments, most of them use empirical values. Corresponding experimental verification

Due to the lack of accurate design basis and theoretical guidance, choosing an empirical value with a too large safety factor will increase the construction cost of artificial reefs, which is contrary to the original intention of building a resource-saving society; choosing an empirical value with a too low safety factor will lead to instability. However, considering the stability and cost of artificial reefs alone will ignore the flow field effect of artificial reefs, and the flow field effect is the key factor for artificial reefs to function
