Liquefaction of the soil surrounding the pile foundations poses a risk of diminishing their load-carrying capacity in the event of earthquake. Consequently, liquefaction of the soil may lead to lateral spreading, exerting additional lateral forces on the piles and potentially causing failure. When soil liquefaction is a concern, it is often preferable to address it through mitigation rather than solely relying on designing the larger diameter piles with heavy reinforcement to accommodate seismic forces. The present study covers a specific case where liquefaction mitigation is addressed through ground improvement using vibro compaction. Pre- and post-Cone Penetration Tests (CPTs) were conducted to quantify the effectiveness of the improvements of the treated ground. The findings reveal that the implementation of ground improvement has significantly mitigated liquefaction. This paper also outlines the enhancement of lateral pile capacity post improvement of the ground. OpenSees platform is used for analysis of laterally loaded piles with the improved soil conditions, and the results are compared with field lateral pile load test results. The numerical results are in well in agreement between numerical simulations and field test data.
