A Study on the Dynamic Strength and Index Model of Artificial Structural Loess

Buildings
Loess is a distinctly structured soil. Undisturbed loess is prone to geological hazards, such as liquefaction and landslides under dynamic loads. There are also problems such as the inhomogeneity, anisotropy, and disturbance of in situ sampling.
