【 摘 要 】

With the increasingly stringent of environmental protection requirements of the China, there is fewer and fewer land reclamation projects, so the related research on dredged soil treatment technology has become a hot spot. A new type of mud-sand interbedded structure is put forward in this paper. The dredged soil is filled in membrane bag and interbedded with sandy membrane bag, which gradually forms a stable new seawall core structure. From the finite element simulation results, it is known that the maximum displacement of mud-sand interbedded structure is 2.73 m. After the calculation, the top surface of the mud-sand interbedded structure is 1.9 m from the back surface, and the compression of the mud-sand interbedded structure is mainly occurs in the middle of the body, the bottom and top are less compressed. The design and construction of the breakwater meets the engineering requirements, and it is a feasible and fast breakwater technology on soft soil foundation.
