摘要： Chemical, physical, mineralogical, beneficiation, and agglomeration studies found the offshore limemud as a potential replacement for limestone in the cement, filler, blast furnace, steel melting shop, lime production, paint, and Grade-I steel industries. An assessment of mining and transportation costs indicates that the offshore limemud (USD 5–6/ton) is more cost-effective than that imported from other countries (USD16-18/ton). With several advantageous factors like low impurity, mode of occurrence in overburden-free stratified form, fine-grained slurry nature, and shallow water depth, sustainable mining of offshore limemud could be a future reality with controllable technological, economic, and environmental challenges.

关键词：Physical and mechanical properties microstructures of submarine soils in the Yellow Sea
摘要：AbstractIn recent years, the exploration of seabed has been intensified, but the submarine soils of silt and sand in the Yellow Sea area have not been well investigated so far. In this study, the physical and mechanical properties of silt and sand from the Yellow Sea were measured using a direct shear apparatus and their microstructures were observed using a scanning electron microscope. The te...

关键词：Mechanical responses of underground carriageway structures due to construction metro tunnels beneath the existing structure A case study
摘要：1 INTRODUCTIONDue to the convenience and efficiency of metro lines, increasingly more cities are planning and constructing new metro lines. Therefore, traversing of a new tunnel traverses around existing structures is becoming common, resulting in the formation of a structural system including tunnels, underground stations, building foundations, and so on (Chen et al., 2016; Guo, 2011; Huang et...
