Study on effect of barrier of a row of hollow pipe piles on isolation of incident plane SV waves

According to the multiple scattering of elastic waves by a row of cylinders in cylindrical coordinate systems,supposing that the interface of hollow pipe piles and soils was coherent,and stresses and displacements were continuous,a theoretical solution of scattering coefficients of incident plane SV waves by the barrier of a row of hollow pipe piles was obtained.By studying the normalized vertical displacement amplitude,the ratio of vertical displacement amplitude of soils behind the barrier to the amplitude of the incident SV waves,the effects of different types of barriers on the isolation of incident plane SV waves were compared,and the influence of displacement between the center of the two adjacent hollow pipe piles,the location of the barriers and the shear modulus or rigidness of the hollow pipe piles on the effect of isolation of the incident plane SV waves were discussed,and it would provide theoretical basis for the design of discontinuous barrier for vibration isolation.
