In the combination with the engineering practice of dike construction by bagged-sand in Yangtze River estuary, the stability of the bagged-sand dike is demonstrated in terms of the reinforcement mechanism, failure mode, calculating methods etc. The reliability of the bagged-sand cofferdam is analyzed from the perspective of bagged-sand material's selection and anti-aging tests etc. The future research issues are put forward from the aspects of coordination between the bagged-sand cofferdam design and relative technical code as well as the durability. The theoretical and practical basis is provided for wide application of bagged-sand cofferdam.
