Soil utilization of solid waste: Small-strain dynamic properties and microscopic mechanism of phosphogypsum-modified coastal cement soil

Journal of Materials Research and Technology
Phosphogypsum (PG), a solid waste from the wet process phosphoric acid industry, but the utilization rate is low at present. The effect of phosphogypsum and cement on small strain dynamic characteristics of coastal soft soil was studied by resonance ...

Experimental study on the determination of small strain-shear modulus of loess soil

HBRC Journal, 2016
The primary aim of this study was to investigate the collapse potential of loess soil in Egypt, the factors affecting the dynamic properties of this soil and establish relationships between them. Whether engineered or natural, may exist in seismic zones;

In-situ material damping measurements using the crosshole seismic method [PDF]

E3S Web of Conferences
Crosshole seismic testing is commonly used to determine detailed and reliable wave velocity profiles. Material damping measurements can also be performed in crosshole seismic testing, but these measurements require a window function to maintain similar ...

A refined method for determining equivalent radius (Req) in resonant column tests across a wide strain range

International Journal of Geo-Engineering
The equivalent radius $$\:{R}_{eq}$$ has been used for calculation of strain in Resonant Column (RC) testing. Present calculation methods for $$\:{R}_{eq}$$ are not adequate since they are not precise over a wide range of strain.

Research on Arc Extinguishing Characteristics of Single-Phase Grounding Fault in Distribution Network

Energies
The development of a single-phase grounding fault arc is influenced by various environmental factors, which can result in the rapid extinction and reignition of the arc. This phenomenon can lead to accidents, such as resonant overvoltage.
