Study on the Material Composition and Engineering Properties of Flowing Mud

In offshore engineering and river dredging projects, flowing mud is often encountered during construction. This kind of silt has the characteristics of high mobility and extremely poor engineering properties, which must be removed during the construction process, causing great trouble to the engineering construction. In this paper, the physical and mechanical properties of flowing mud in coastal areas are analyzed through indoor tests. It is found that the flowing mud has the characteristics of high water content, high compressibility, low consolidation coefficient and low shear strength, and the shear strength of the flowing mud is significantly increased after the consolidation is completed, which indicates that the drainage consolidation method is completely feasible to treat this kind of soil in theory.
