The article looks at how different treatments for soft ground affect nearby pile foundations under pressure. By studying real sites and using computer simulations, the researchers found that weak layers in the ground have the biggest impact on piles closest to the edge, causing the most deformation. To improve this, side piles should be made stronger, and certain treatments like cement mixing or rigid piles can help. Rigid piles work better than cement mixing. The best treatment distance from the pile is around 8 meters, not too close or too far.
