Numerical simulation method for dynamic process of spudcan penetration

Based on the coupled Euler-Lagrange (CEL) method, the process of spudcan penetration is simulated, and several parameters affecting the calculated results are analyzed. The results show that the reasonable parameters in the CEL method can effectively simulate the penetration resistance results of centrifugal model tests. The large mesh size in the model will cause the calculated results to shake, so it is recommended to take 0.05 times the diameter of spudcan. Slow spudcan penetration speed v, has small influences on the lower penetration resistance, and it is recommended to be 1 m/s. The friction coefficient f between spudcan and soil has small influences on the penetration resistance, and smooth contact is recommended in clay. The lateral pressure coefficient K₀ of the geostress step should be coordinated with other soil parameters, and it is recommended to be 1 for clay.
