Pore pressures and strains after repeated loading of saturated clay [PDF]

, 1974
Repeated and sustained loading tests on undrained samples of normally consolidated lacustrine clay are used to prove the existence of a relationship between pore water pressures and axial strains.The behavior of the clay is studied by investigating the ...

Accumulation of Pore Pressure in a Soft Clay Seabed around a Suction Anchor Subjected to Cyclic Loads

Journal of Marine Science and Engineering, 2019
A suction anchor is an appealing anchoring solution for floating production. However, the possible effects of residual pore pressure can be rarely found any report so far in term of the research and design.

Changes in excess pore water pressure in soft ground under multi-factor influences coupled with positive and negative pressure

Shuiwen dizhi gongcheng dizhi
Vacuum stacking joint pre-compression method is widely used to reinforce soft ground. During the preloading process, a coupled mechanism involving positive and negative pore-water pressures develops within the soil, and the reinforcement performance is ...

Experimental Investigation of Pore Pressure on Sandy Seabed around Submarine Pipeline under Irregular Wave Loading

Sensors
The propagation of shallow-water waves may cause liquefaction of the seabed, thereby reducing its support capacity for pipelines and potentially leading to pipeline settlement or deformation.

Dynamic simulation of“12·20”Shenzhen landslide

Yantu gongcheng xuebao, 2018
The filled soil of Shenzhen landslide is treated as saturated porous media. The excess pore pressure due to fast filling process is derived using the classical one-dimensional consolidation theory by assuming the thickness of the filled soil to increase ...

Blast Liquefaction Test of Saturated Sand Foundations Disposed by a Drainage Rigid Pile

Shock and Vibration, 2022
Drainage rigid piles represent a commonly used antiliquefaction treatment for saturated sand foundations. Small-scale model tests on the liquefaction-resistant characteristics of drainage rigid piles subjected to blasting were conducted in this study ...

Effect of DFPP on Ferroptosis in Peripheral Blood CD14+ Monocytes of Hyperlipidemic Patients Involving the ACSL4/LPCAT3/ALOX5 Pathway

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Hyperlipidemia is a major risk factor for atherosclerotic cardiovascular disease (ASCVD). Although statins are the cornerstone of lipid‐lowering therapy, their use may be limited in some patients by adverse effects. This study evaluated the possible impact of non‐drug treatment using double‐filtration plasmapheresis (DFPP) on CD14+

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
