- Abstract:
- The torsional vibration of soil is solved by separation variable method by considering interaction be.tween pipe pile and soil under axisymmetric condition, and the torsional vibration of pipe pile in soil is investi-.gated with the orthogonality of trigonometric functions by considering the boundary conditions of soil and pipepile, and the influenee of related parameters on the coupling torsional vibration of pipe pile, The research in.dieate that the resonance phenomenon is existed, and the radius ration between inside and outside of pipe pileand modulus ratio between and pile around soil have great effect on the complex stiffness of pipe pile at head.but the influenee of modulus ratio and density ratio between inner soil and pile around soil is very little at lowerfrequency, but the influence is larger at higher frequency.
