Stability analysis of geotube groin during construction

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.
