Son yirmi yılda, farklı deneysel yöntemler alan ve laboratuvar test verilerine dayandırılarak hacimsel gerilme (zemin oturması) ve maksimum kayma gerginliğini belirlemek için kullanıldı. Bu çalışmanın temel amacı, zemin sıvılaşmasından sonra zemin oturma oranı oranının değerlendirilmesi ve sıvılaşma potansiyel endeksi (LPI) ile oturma arasındaki çalışma ilişkisinin değerlendirilmesidir. Tebriz Metro 2 Hattı boyunca Standard Penetrasyon testi (SPT) 54 sondaj deliğindeki sonuçlarından zemin katmanlarının sıvılaşma potansiyelini tahmin etmek için kullanıldı. Daha sonra hem kuru hem de doymuş zemin katmanlarında sıvılaştırmaya bağlı olarak zemin katmanlarında oturma oranı hesaplanmıştır. Devamında LPI hesaplanmıştır. Çalışmadan elde edilen sonuçlar gösteriyor ki, doymuş zemin katmanlarındaki oturma oranının, yeraltı su seviyesinin üzerindeki zemin katmanlardan belirgin derecede yüksek olduğunu ve zemin katmanlarının yoğunluğunun arttığında oturma oranının ve zemin hacimsel gerilimin azaldığını gösterdi. Ayrıca, zemin katmanlarında LPI ve zemin oturma değerleri arasında iyi bir uyum var.
