Quality control and construction technologies for seadike on soft soil foundations

Abstract

    Sea dikes and estuary dikes of Vietnam have been constructed in a long time with different quality. Most of them had constructed on the natural lines in which the foundation is very complicated. When a land is increased, a new line of dike will be relocated, that a new dike will be laid on the soft soils. The safety and economic of new dike as well as short time of construction are depended on construction method. The construction method for sea dike on soft soils with high seepage, low strength and settlement will be presented and discussed in this paper. In Vietnam, construction methods used for soft foundation will be sand- sub base, strengthening of foundation, control settlement referring to consolidation
