... vertical displacements occur in the soil plug inside the DSA and adjacent to the skirts. Concentration excess pore pressure was observed around at the tip of the skirts and adjacent to the stiffeners. In addition, it was found that the presence of post-lay rock at the vicinity of DSA considerably affects...

... =0.04mm). Results show that the buried soil reduces the excess pore pressure around pipeline and provides a degree of resistance to seabed liquefaction, and the excess pore pressure around the circumference of pipeline or beneath the pipeline is larger in the coarser backfill sand, and decreases...

... Asia, which requires a foundation design that is able to withstand the effects of seismic loading. The seismic load from e.g. an earthquake is cyclic by nature. This type of loading can lead to generation of excess pore pressure in the soil. In loose (contractive) soils, the generated excess pore...

... the mechanism of the suction generation and the contributing factors. Based on studies of the excess pore pressure development process, the suction generation process is divided into three stages. With parametric studies, a formula is proposed to calculate the ratio of actual suction to the ultimate suction...

... dependency of clayey soil is represented by an elasto-viscoplastic soil model. The numerical model is validated against existing centrifuge testing data. The anchor deceleration profiles and the development of excess pore pressures around the anchor are discussed. A parameteric study is then conducted...

... (Herbich et al., 1984; Christian et al., 1974). In general, ocean waves propagating over the seabed can exert dynamic pressure fluctuation in the soil skeleton, and further generate excess pore pressure accompanied with a decrease in effective stress within the seabed soil. As a result, the seabed...

Furthermore, the derived liquefaction resistance was compared to the test results of 3 irregular wave loadings with various waveforms and durations...

... Abstract Cyclic loading of saturated sand will result in the generation of excesspore pressures. The amount of excess pore pressure depends not only on the soil properties, but also on the rate of dissipation and the loading history. In this study an approach is described to take into account...
