That the bamboo structures replace the traditional riprap and bagged sand dike as reclamation area partition dike is a new design idea.In order to understand the overall safety and stability and reasonable scale of the new embankment structure under the effect of land reclamation soil pressure，the paper analyzes the factors affecting the stability of the overall safety based on the bamboo structure construction of external condition.Impoundment is used to balance soil pressure.Element software PLAXIS is used to calculate different projects composed of different water heads and different number of spans of bamboo structure.
