“…The relationship between the coefficient of viscosity and excess pore pressure ratio (u/σ c ) adopted in this study is given in Figure 5. For the soil domain, the TEPP is introduced, and the state equation is described in Equation (1). In this study, the coefficient of viscosity, η ∞ , of the liquefiable soil ranges from 60 kPa•s to 2000 kPa•s depending on the completeness of its internal structure, which could be indicated by the generation of excess pore pressure ratio in the soil.…”

“…Earthquake liquefaction has a great influence on infrastructure such as structures and buildings and has become a hot research topic. The pile foundations of existing buildings and structures have been severely injured by liquefaction-induced lateral spreading during several earthquakes [1][2][3]. In the 1964 Niigata earthquake, the famous Showa Bridge caved because of liquefaction-induced lateral displacement [4].…”

One of the challenges to the analysis of interactions between soil and piles in lateral spreading is the modeling of the progress generated by excess pore pressure and soil strength and stiffness degradation. In this paper, a pile–soil interaction analysis method that introduces the thixotropic-induced excess pore pressure model (TEPP) to describe the progressive development of the stress–strain rate connection of liquefying soil is proposed. The reliability of the method was verified by comparing the calculated results with that of the shake table test. Then, the parametric analyses of soil–pile interactions were carried out. The results show that the bending moment and horizontal displacement of pile foundations increase with the increase in superficial viscosity and inclination angle of the site. The horizontal dislocation and bending moment of the pile foundation increase with the decrease in loading frequency as a result of the property of amplifying low-frequency loads and filtering high-frequency loads of liquefied soil.

This study examines the impact of soil liquefaction on buildings supported by piles driven into the ground, focusing on the structural response and potential consequences when the ground temporarily loses its strength and becomes unstable during seismic loading, such as earthquakes. To enhance safety and mitigate the risks associated with soil liquefaction, proactive measures are being considered, such as conducting thorough ground investigations before construction, implementing ground improvement techniques, and employing meticulous engineering and design practices when planning buildings supported by piles in regions prone to ground weakness during seismic events. This research is essential for advancing our comprehension of the impact of soil liquefaction on pile-supported buildings and for developing strategies to enhance structural stability in regions prone to liquefaction, providing valuable insights for engineers and builders committed to creating earthquake-resistant structures and ensuring the safety of communities in seismic-prone areas.
