- •
Dynamic impedance will be not affected by the number of soil layers when n≥100.
- •
Dynamic impedance increases as the central angle increases at low frequencies.
- •
Contact factors of plate–soil system can influence the dynamic impedance heavily.
- •
The length of the support plate should be designed according to requirements.
- •
Dynamic impedance decrease as the embedment ratio of the support plate increases.
