土工填充管袋丁坝具有施工周期短、工程费用低等优点,具有一定的工程应用前景,但目前设计和施工尚无具体规范。建立流固耦合数学模型,分析管袋丁坝施工期各阶段的流场变化、丁坝坝堤上的动水压力变化以及丁坝坝体内的应力、应变分布,其计算成果可为管袋丁坝设计和施工提供一定的参考依据。

Geotube groin with advantage of short construction period and low engineering expense has a good prospect of engineering application,but there is no code for design and construction of the structure.The fluid-solid coupled mathematical model is developed to analyze the change of flow field,the variant of hydrodynamic pressure on the surface of groin and the distribution of stress and strain in the groin during the construction.The result can be reference for design and construction of geotube groin.
