Experimental Study on Different Improvement Schemes of EICP-Lignin Solidified Silt

Yongshuai Sun et al.

Summary: This paper mainly studies the effects of urease, lignin, and their mixture on the strength and liquefaction resistance of silt. Different improvement schemes were analyzed based on unconfined compressive strength and dynamic triaxial tests, and optimal values were obtained for the addition of cement or lignin. The results showed that the optimal concentration of urease was 1.0 mol/L and the optimum addition ratio of lignin was 3% for improved silt.

Seismic performance assessment of wall-type gravel and rubber drains in liquefaction mitigation of sands

Araz Hasheminezhad et al.

Summary: This paper investigates the performance and application of wall-type gravel and rubber drains in liquefaction mitigation. The results show that increasing the width and number of the drains can reduce settlement and liquefaction-induced deformations, as well as excess pore water pressure, improving the sand's resistance to liquefaction.

Effects of variations of voltage and pH value on the shear strength of soil and durability of different electrodes and piles during electrokinetic phenomenon

Fatemeh Sadeghian et al.

Summary: Electrokinetic (EK) treatment is effective in accelerating soil consolidation and improving geotechnical properties, but electrode corrosion and loss of electrical potential may reduce efficiency. The voltage applied during the EK process significantly influences the treatment efficiency, and careful selection of the optimal voltage is crucial.

Influence of structure on the aseismic stability and dynamic responses of liquefiable soil

Pengfei Dou et al.

Summary: The study on seismic response and stability of liquefiable sites with and without structures found that non-free field has higher natural frequency and lower damping ratio. Under weak seismic loading condition, similar dynamic response is observed in both sites. However, under strong ground motion condition, the presence of structures in the non-free field leads to lower liquefaction depth, slower accumulation of porewater pressure, and smaller lateral displacements and acceleration compared to the free field.

Centrifuge and numerical modelling of earthquake-induced soil liquefaction under free-field conditions and by considering soil-structure interaction

A. G. Ozcebe et al.

Summary: This paper focuses on the modelling of earthquake-induced soil liquefaction and its consequences on overlying buildings using physical and numerical modelling techniques. The presence of a structure increases vertical effective stress and leads to a concentrated strain field near the foundations, resulting in stronger response and larger settlements compared to the free-field conditions.

Megazonation of earthquake-induced soil liquefaction hazard in continental Europe

F. Bozzoni et al.

Summary: Mapping liquefaction hazard at a continental scale is challenging due to the localized nature of soil liquefaction. However, continental charts of liquefaction hazard can help policymakers prioritize urbanized territories for further investigation to assess seismic risk. These charts are useful despite the low accuracy at a local scale.

Energy-based model for predicting liquefaction potential of sandy soils using evolutionary polynomial regression method

Ali Ghorbani et al.

Summary: The study introduces a comprehensive energy-based model for evaluating liquefaction potential in sandy soils, taking into account factors such as Plasticity Index and loading Frequency. The model was developed in two steps, validated with 100 worldwide case histories, and found to be superior to previous energy-based models. Parametric analysis showed that fine content and Plasticity Index are the main factors influencing liquefaction capacity in sandy soils.

An experimental evaluation of helical piles as a liquefaction-induced building settlement mitigation measure

Milad Jahed Orang et al.

Summary: The study evaluates the use of helical piles to reduce liquefaction-induced foundation settlement and investigates their seismic performance in liquefiable grounds. The experimental results showed that helical piles can reduce excess pore-water pressure generation and prevent foundation tilt and settlement in liquefiable grounds. However, the design and application of helical piles need further investigation to prevent possible amplified superstructure response.

Liquefaction and reliquefaction resistance of saturated sand deposits treated with sand compaction piles

Gowtham Padmanabhan et al.

Summary: To improve liquefaction resistance in sandy deposits, techniques such as Sand Compaction Pile (SCP) were used in the field. A series of shaking experiments on SCP treated and untreated sand deposits were conducted under repeated incremental acceleration loading conditions, showing improved soil resistance and relative density, as well as the dissipation of excess pore water pressures. The seismic response of liquefiable sand deposits was significantly enhanced by SCP installation and continuous soil densification under repeated loading was observed, suggesting that SCP can perform better during repeated shaking events.

Seismic response of non-connected piled raft foundations

Maryam Saadatinezhad et al.

Summary: This paper investigates the behavior of non-connected piled raft foundations (NCPRFs) subjected to earthquake loading, highlighting that pile slenderness ratio and raft thickness are essential factors in evaluating dynamic response. The comparison between CPRF and NCPRF shows that the latter leads to less shear force and bending moments along the piles, resulting in a more economical design.
