The technology of mud-filled bag filled with sand plays a good role in the construction of the dike in the Yangtze Estuary. However, the dike embankments are mainly built by powder materials with high permeability, and the shallow strata of dike foundation normally consist of silt and silty sand, which are moderately permeable and prone to seepage deformation. Under the action of water head difference, levee and foundation soil may produce leakage and seepage deformation. Therefore, seepage control measures should be taken for the reservoir embankments. According to the characteristics and difficulties of the seepage control measures in this project, many schemes are compared, and the final form and construction parameters of the impervious structure are determined based on the field prototype tests. A detailed calculation of the flow control of the recommended scheme is given, and it may can provide reference for similar projects. © 2016, Chinese Society of Civil Engineering.
