新型泥砂互层结构埝体变形特性.

With the increasingly stringent requirements lor environmental protection in China, the research on dredged soil treatment technology has become a hot spot. A new type of embankment with mud—sand interhedded structure is put forward in this paper. The dredged soil is filled with membrane bag and interhedded with sandy membrane bag, which gradually forms a new stable embankment core structure. Through the finite element simulation results, it is known that after 55 d of consolidation, the maximum displacement of mud—sand interhedded structure is 2.73 in, and the top surface of the mud—sand inteibedded structure is 1.9 in from the back surface. The compression of the mud—sand interhedded structure is mainly occurs in the middle of the body, and the bottom and top are less compressed. The design and construction of the embankment meets the engineering requirements, and it is a feasible and last embankment technology on soft soil foundation. [ABSTRACT FROM AUTHOR]
