Abstract: In order to better promote soilbag revetment and verify the broad application prospects of soilbag underwater revetment technology, this article, based on previous theoretical research results, focuses on the design of soilbag unit body, stability verification, and selection of geotextile fabric materials, and completes the soilbag body design of the deep groove protection project on the right edge of the Baguazhou Head.After actual construction, the underwater revetment structure section of the project is tested using a multibeam depth measurement system to verify the engineering effect.The results indicate that the design process of the bag body is feasible, saving stone resources and achieving remediation effects, providing a reference for similar bag body designs in future shore protection projects.
