Study on the Solidification Effect of Dredger Fill by Microbial-Induced Calcium Precipitation (MICP) [PDF]
Materials, 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 ...

Study of the sorting pattern of dredger fill under artificial disturbance based on the concealment degree [PDF]
Scientific Reports, 2022 This paper focuses on the sorting pattern of silt deposited at estuaries under artificial disturbance based on the concept of bidirectional concealment, which is introduced for such silt with similar particle size, low disturbance exposure angle, and ...

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 ...

Research on the Pore Characteristics of Dredger Fill By Preloading
Lecture Notes in Civil Engineering, 2023 AbstractThis study investigated the characteristics of dredger fill after preloading at the DaLian. Granulometric composition test and X-ray diffraction were employed to determine the composition of dredger fill. Mercury intrusion porosimetry was combined to determine the related features of the pore.

Interface shear characteristics of dredger fill and concrete using large size direct shear test
International Journal of Geo-Engineering, 2018 A large-size direct shear test was conducted to test the interface of dredger fill and concrete. The effect that concrete strength and the density of dredger fill have on the properties of interface is then analyzed.

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.
