Abstract
This paper describes a theoretical investigation into the way in which the coupling conditions between a buried plastic water pipe and the surrounding soil affects the propagation characteristics of the fluid dominated wave in the pipe. Of particular interest, is whether the axial coupling between the pipe and the soil is an important factor for a typical Brazilian water pipe system. For typical soil in São Paulo city, it is found that shear modulus of the soil has a profound effect on the wave motion in the pipe, and this is mainly through radial rather than axial coupling between the pipe and the soil.
