An Investigation of Time-Dependent Deformation Characteristics of Soft Dredger Fill [PDF]
Advances in Civil Engineering, 2020 The creep characteristics of soft clays have been studied for decades. However, the lateral deformation of soils is not allowed during the commonly used one-dimensional consolidation tests, which cannot describe the real deformation features of soils in ...

Study on the Solidification Effect of Dredger Fill by Microbial-Induced Calcium Precipitation (MICP). [PDF]
Materials (Basel), 2022 This paper puts forward a new soft soil reinforcement technology—microbial-induced calcite precipitation (MICP) technology—which considers the problem of dredger fill soft-soil reinforcement in Dalian Taiping Bay. In this paper, the calcium carbonate content (CCC) and unconfined compressive strength (UCS) of microbial solidified dredger fill (MSDF ...

Vacuum Preconsolidation Settlement Characteristics and Microstructural Evolution of Marine Dredger‐Filled Silt [PDF]
Advances in Civil Engineering, 2021 The method of vacuum preloading for foundation treatments is used in the construction of the Fangchenggang coastal area in Guangxi province, China. The thick marine dredger‐filled silt has a considerable impact on the treatment effort. In this study, the mineral composition and grain size distribution of these silts were analyzed to investigate their ...

3D DEM simulation of initial anisotropy in dredger fill soft soil
IOP Conference Series: Earth and Environmental Science, 2021 Abstract The initial anisotropy has a significant effect on the mechanical properties of the soft soil. Based on the initial anisotropy of the particles, the mechanical characteristics are analysed from a microscopic view, and the micro-macro relationship of the soil is established.

Experimental study on flocculation-accelerated deposition of dredger fill
Yantu gongcheng xuebao, 2017 After hydraulic reclamation of the dredger fill, the mud needs some time to deposit. The reinforcement treatment cannot be carried out until the sludge-water separation is completed and the separated water is drained.
