New Construction Method of Marine Cofferdam on the Soft Ground in Tideland

Abstract:

The marine cofferdams of the littoral new town in Lianyungang were constructed with geotextile bags filled with solidified soil and the soft ground under the cofferdams was treated by under water vacuum preloading method. The dimension of the cofferdams was reduced while the foundation kept stable. And the cofferdams were configurated with the geotextile bags filled with solidified soil, the silt clay was utilized adequately, the sand stone resource was saved and protected, the obvious effect was achieved. This method can be promoted in construction of marine cofferdams.
