...Zhengtao Shen; Yue Xu; Yuanyuan Geng; Fei Jin; Benyi Cao; Huan Liu; Chao-Sheng Tang; Bin Shi The erosion-induced environmental risks of contaminated soil and the corresponding remediation strategies remain inadequately understood. This study investigates the effect of reactive magnesia (MgO), a low...

...Danial Haider; Chao Zhou Internal soil erosion is a major cause of failure in embankment dams, slopes and sea walls. Although several constitutive models have been proposed to simulate soil erosion and its impacts on soil behaviour, they are not able to capture the accumulation of erosion under...

..., resulting in more complex contact erosion responses between soil layers. In this study, a coupled computational fluid dynamics–discrete element method (CFD–DEM) was employed to investigate the effects of different mean hydraulic gradients and cyclic hydraulic gradient amplitudes. The research focused...

...Teing Teing Tan; Ali Akbar Karimzadeh; Anthony Kwan Leung The behaviours of soil subjected to internal erosion have been widely investigated, yet the evolution of soil fabric anisotropy during erosion and the corresponding changes in post-erosion stiffness degradation curves have never been...

This study examines internal erosion during shearing of granular soils under triaxial loading conditions...

...Guo-Qing Cai; Xian-Feng Diao; Xu-Zhen He; Shuai Gao; Tao Liu Different layers of soil often have distinct particle sizes. When exposed to the natural environment, soil is easily affected by natural rainfall, rising groundwater levels and human activities, leading to particle contact erosion, which...

...Huaxiang Yan; Majid Sedighi; Andrey Jivkov; Abdelmalek Bouazza Recent laboratory and field experiments have provided evidence of the erosion and piping of clay-based barriers. Predicting these phenomena is essential for the performance assessment of bentonite barriers and containments. This paper...

...Zhijie Wang; Caglar Oskay; Alessandro Fascetti Backward erosion piping (BEP) has been recognised as a major cause of failures in water-retaining structures. However, the fundamental mechanisms controlling the phenomenon are not well understood. This research applies the theory of rate processes...

...Majid Sedighi; Huaxiang Yan; Andrey P. Jivkov Experimental observations of the erosion of clays indicate a high degree of coupling between the hydro-chemical processes in the clay–water system and the mechanics of erosion. In contrast with the volume of experimental work and the significance...

... sandy soils, whereas the roadbed is constructed from well-graded gravel. A concrete base about 20 m long, 3·0 m wide and 0·3 m thick is directly constructed over the roadbed, and a concrete capping layer is installed on the roadbed shoulder to avoid rainwater infiltration and roadbed erosion...

...Andrea Ciancimino; Liam Jones; Lampros Sakellariadis; Ioannis Anastasopoulos; Sebastiano Foti Scouring around piers is recognised as one of the main causes of bridge failure. Local scour refers to the localised erosion of soil at piers and abutments caused by flow-induced vortices around their base...

...Chen Chen; Limin Zhang Numerous incidents and failures of earth slopes, dykes, levees and embankment dams are caused by internal erosion. At a time of global climate change, rapid pore-water pressure changes in soil masses are frequently induced by extreme rainfall, storm surges, waves, flash...

...Xiaogang Qin; Ian D. Moore Water infiltration is one of the most significant underlying causes of deterioration in buried rigid pipes, which can bring about erosion voids in the backfill that will increase the severity of the soil loading and produce structural failures. Based on model tests...

...Esther Rosenbrand; Vera van Beek; Adam Bezuijen The coarse sand barrier (CSB) is a novel remediation measure to reinforce embankments against the internal erosion mechanism of backward erosion piping (BEP). The feasibility of the CSB is investigated in a research programme consisting of experiments...

The physical mechanism by which a pipe progresses upstream beneath the embankment is conceptually...

... unfiltered seepage exits that may lead to initiation of backward erosion piping (BEP) in the foundation materials. Further progression of the backward erosion process may undermine the embankment, ultimately leading to collapse and breach. As the progression of BEP is dependent on the horizontal hydraulic...

Internal erosion of the finer soil fraction driven by the seepage forces is thought to have played a significant role...
