Excess pore water pressure and seepage in slopes induced by breaking internal solitary waves

Zhuangcai Tian et al.

Summary: This study simulated the breaking of ISWs using LES and analyzed the pressure induced by ISWs. It was found that the polarity of ISW-induced pressure changed when they propagated over slopes, and the rate of polarity change increased with an increase in slope angle. Additionally, two distinct seepage fields existed in the seabed with sloping topography, leading to different failure risks in different parts of the seabed.

Numerical Investigation of the Landslide Cover Thickness Effect on the Drag Forces Acting on Submarine Pipelines

Xingsen Guo et al.

Summary: This study investigates the influence of submarine landslides on pipelines, specifically focusing on the thickness of the landslide cover, pipeline diameter, and span height. It is found that increasing the landslide cover thickness leads to an increase in drag force on the pipelines, although the growth pattern varies depending on the span height condition. The study proposes a reference value for the drag force coefficient and an adjustment factor, and establishes a standardized chart methodology for evaluating drag forces.

In-situ observation of seabed vertical deformation in Yellow River Delta under storm surges

Cong Hu et al.

Summary: Sediment destruction is a significant threat to marine engineering facilities in river delta areas, often caused by the vertical deformation of the seabed during storm surges. This study developed an in-situ observation system, including high-precision water pressure sensors and acoustic Doppler current profilers, to monitor the seabed vertical deformation. Through applying this system and processing method in the Yellow River Delta, the vertical settlement of seabed during storm surge events was quantitatively analyzed, and a mechanism for seabed vertical deformation was established.

A methodology to predict the run-out distance of submarine landslides

Xingsen Guo et al.

Summary: In this study, the method of computational fluid dynamics (CFD) was used to simulate a fluidized submarine landslide with shear thinning non-Newtonian fluids under different contact conditions. The accuracy of the CFD method was validated and various experiments were systematically performed. The stress state and causes of the submarine landslide mass during its movement in ambient water were revealed, and the submarine landslide-seabed contact relation was identified as a decisive influencing factor. Furthermore, a methodology based on energy conservation was presented to predict the run-out distance of the submarine landslide mass, and equations to quantify the process were established and validated by numerical results. This provides a significant basis for the prediction of marine engineering geological and hydrodynamic hazards related to submarine landslides.

Wei Shao et al.

Summary: This study investigates the durability life and horizontal bearing characteristics of carbon fiber reinforced polymers (CFRP) composite piles in marine environments. The durability life of CFRP composite piles is divided into the initial corrosion stage and the crack propagation stage. A chloride diffusion model and Monte Carlo simulation method are used to predict the initial corrosion time, while a durability life prediction model for the crack propagation stage is established. The bending stiffness reduction factor of CFRP composite piles with different replacement ratios is obtained, and the attenuation law of bending stiffness and horizontal bearing characteristics are analyzed.

Deep seabed mining: Frontiers in engineering geology and environment

Xingsen Guo et al.

Summary: Ocean mining activities have been ongoing for nearly 70 years, contributing greatly to industrialization. With the increasing energy demand and efforts to achieve a low-carbon economy, deep seabed mining will play a crucial role in addressing energy and resource-related issues in the future. However, deep seabed mining is still in the exploratory stage and faces challenges posed by the high-pressure, low-temperature, and complex geologic and hydrodynamic environments in deep-sea mining areas, which are inaccessible to human activities. It is necessary to make considerable efforts to ensure sustainable, economic, reliable, and safe deep seabed mining.

Morphology and origin of liquefaction-related sediment failures on the Yellow River subaqueous delta

Hong Zhang et al.

Summary: The bottom morphology of the Yellow River subaqueous delta is highly complex, with a moderately disturbed area and a heavily disturbed area. The heavily disturbed area shows evidence of liquefaction-related sediment failure and is divided into four morphological zones. Sub-bottom profiles reveal erosion as the main cause of failure features in Zone 1, while Zones 2-4 lack internal structures and display chaotic/disturbed signatures, indicating liquefaction. The formation mechanism for these features involves sediment liquefaction, resuspension, resolidification, and erosion.
