This study examines the impact of nozzle structural parameters on soil-breaking depth and width. Utilizing the Arbitrary Lagrange-Euler (ALE) algorithm, a finite element model for submerged water jet soil-breaking was established and validated through laboratory experiments. Response surface methodology was employed to optimize nozzle parameters, analyzing the effects of cone angle, diameter, and length on soil-breaking outcomes. Findings indicate that nozzle diameter exerts the most significant influence on both depth and width, while the interaction between diameter and cone angle has the most pronounced effect . By integrating a satisfaction function and using soil-breaking depth and width as evaluation metrics, the nozzle design was optimized. The optimal parameters identified for the conical nozzle are a cone angle of 12.21°, a diameter of 1.16 mm, and a length of 2 mm, achieving an optimal balance between depth and width.
