Torsional dynamic response of tapered pile considering compaction effect and stress diffusion effect
Publikováno v:
Journal of Central South University. 27:3839-3851
Considering both the compaction effect of pile surrounding soil and the stress diffusion effect of pile end soil, this paper theoretically investigates the torsional vibration characteristics of tapered pile. Utilizing the complex stiffness transfer
