“…The weight of the fibrous material used for each fiber content is calculated based on the air-dried soil weight ( Al-Refeai, 1991 ; Maher and Ho, 1994 ; Tang et al., 2007 ; Mollamahmutoglu and Yilmaz, 2009 ; Amir-Faryar, 2012 ; Amir-Faryar and Aggour, 2012 ; Zaimoglu and Yetimoglu, 2012 ; Li and Senetakis, 2017 ; Wang et al., 2018 ; Develioglu and Pulat, 2021 ; Zhang et al., 2022 ).…”

“…This can be achieved through the use of geosynthetics and geotextiles, such as geogrids and geocomposites, which provide additional tensile strength and stability to soil [119]. Geosynthetic-reinforced soil walls can also be used to stabilize slopes and prevent internal erosion [120][121][122][123][124]. Another approach is the design and implementation of effective drainage systems.…”

This paper employs the systematic literature review (SLR) methodology to investigate the combined effects of seismic vibrations and rainfall on soil suffusion, a process leading to soil instability. Earthquake activity can accelerate soil liquefaction, exacerbating suffusion, while heavy rainfall can increase soil weight, inducing instability. Consequently, the repercussions of seismic activity and rainfall on suffusion may induce further damage and instability to civil infrastructure. The review reveals that the compound impact of rainfall and seismic vibrations can precipitate severe damage and instability, primarily through two mechanisms. First, earthquakes can catalyze soil liquefaction, inciting soil movement and amplifying the suffusion process. Second, heavy rainfall can saturate the soil, augmenting its weight and rendering it unstable, thereby inducing suffusion. However, the review also reveals a significant gap in understanding and mitigating suffusion triggered by simultaneous rainfall and seismic activity. Current techniques for identifying and mitigating such suffusion are inadequate, highlighting the need for further research. This review posits that the interaction of rainfall and seismic vibrations as a catalyst for soil suffusion demands additional scrutiny. It provides a comprehensive understanding of suffusion and the impact of rainfall and seismic vibrations on suffusive soils, serving as a basis for future studies on this important issue.

“…In recent decades, tension-resisting materials have been widely used by various researchers to reinforce the soils, improving the shear strength, density, and compressibility (Rowe and Li 2002 ; Li and Rowe 2008 ; Jones 2013 ; Shukla 2017 ; Lian et al 2020 ; Develioglu and Pulat 2021 ; Wang et al 2021 ). Among these, using randomly distributed fibers to reinforce the soils has recently attracted great interest from researchers and engineers because their performance exceeds that of conventional reinforcements, such as geotextiles, strips, and geogrids (Ye et al 2017 ; Wang et al 2020 ; Bao et al 2020 ).…”

The rapid response to the COVID-19 pandemic has resulted in increased municipal waste in the form of used face masks (FMs), which pose a global threat to the environment. To mitigate this, the study explores the applicability of shredded FMs as alternative reinforcing material in sands. Laboratory-grade Ottawa sand and naturally collected sea sand are adopted as the base sands for testing. The primary physical properties of the base materials and the FMs are first examined, and the soil particles are imaged via scanning electron microscopy. Thirty consolidated undrained (CU) triaxial compression tests were conducted to evaluate the effects of the weight fraction of FM, FM length, and the initial effective mean stress on the undrained shear strength parameters of the sands. The experimental results proved that FM inclusion can lead to a substantial improvement in the undrained shear strength of the sands; however, such improvement was sensitive to the initial effective mean stress, with higher undrained shear strength gains associated with lower initial effective mean stress. For a given FM content, the critical state ratio and angle of friction at the critical state increased with the FM length. Finally, the results revealed that FM-reinforced sands exhibit dilative and strain-hardening behaviors.
