摘要: SUMMARY An analytical solution is developed in this paper to investigate the dynamic response of a large-diameter end-bearing pipe pile subjected torsional loading viscoelastic saturated soil. The wave propagation soil and are simulated by Biot's two-phased linear theory one-dimensional elastic theory, respectively. equilibrium equations outer soil, inner established. solutions for soils frequency domain obtained Laplace transform technique separation variables method. Then, on basis perfect contacts between as well results compared with that solid verify validity solution. Furthermore, classic plane strain further check accuracy Numerical presented analyze vibration characteristics illustrate effect parameters geometry size complex impedance velocity admittance head. Finally, displacement at different depth analyzed. Copyright © 2014 John Wiley & Sons, Ltd.
