The study was carried out based on CPT data. Firstly, the soil nonuniformity of Chengdao Sea at Yellow River estuary was discussed. Then one model for analyzing the liquefaction based on CPT data was established, and the liquefaction degree of Chengdao Sea was calculated. Results show that, liquefaction does not always begin from surface of seabed to down expansion, but easily appear at the weak layer. The soil horizontal nonuniformity induced different liquefaction depths, and can reach 3.65.0 m under 10th storm waves. Under the water and gravity force, the liquefied soil could fail and form rugged topography.
