摘要：

An analytical method was presented for analysis of the torsional vibration of an elastic pile embedded in transversely isotropic saturated soil. The bar-porous medium system was decomposed into an extended transversely isotropic porous medium system and a fictitious pile as a reinforcement. The soil was governed by Biot's three-dimensional elastodynamic theory, and the pile was modeled by one-dimensional elastic theory. Hankel transform was used to solve the dynamic governing differential equations of the saturated poroelastic soil. Considering the mixed boundary-value conditions at the interface of pile and soil, a Fredholm's integral equation of the second kind for the bar-force was established. The bar-force was determined by numerical method, and then the angle of twist of pile. The numerical calculation indicates that the characters of soil and load frequency affect the vibration obviously.
