- W633268015 abstract "Installation of pipelines in congested urban areas using conventional open-cut or cut and fill excavation methods generally causes disruption to traffic and other surface activity. An alternative pipeline installation technique is pipe bursting, where the new pipe is installed by pulling it into place after first breaking apart and pushing aside fragments of the existing pipe. Pipelines installed by pipe bursting are subjected to external pressure due to soil-pipe interaction. This leads to frictional drag as the pipe is pulled into place, an installation load that may be more severe than the operational loads, and which may govern maximum pulling lengths. Field experience also indicates that the invert or axis position of the new pipe may differ from the pipe being replaced, an important consideration for gravity flow sewers. Axisymmetric modeling of the problem using semi-analytical solutions has been proposed as a potential tool for pipe and geotechnical consultants designing bursting projects. However, approximations associated with the axisymmetric solution (homogeneous, isotropic initial stress, and the infinite extent of the soil) require investigation. Furthermore, axisymmetric analysis cannot provide information about relocation of the new pipe axis. These issues are explored using materially and geometrically nonlinear finite element analysis. Incremental earth pressures during bursting are found to be almost axisymmetric, and these dominate the ground stresses. Radial pressures are small for pipes pulled into place within clay, because cavity contraction onto the new pipe brings stresses close to zero. Radial stresses on new pipes installed in sand are higher. By using horizontal earth pressure to normalize stresses, the semi-analytic, axisymmetric solution is found to provide good estimates of those radial pressures. The finite element analysis indicates that changes in pipe alignment are controlled by the zone of shear failure that develops in the overlying soil as the burst head expands the cavity. Before this zone reaches the ground surface, the axis of the burst head remains near the location of the original pipe axis. After this ?plastic zone? reaches the surface, it is the invert elevation of the burst head that remains almost constant. Changes in pipe elevation are particularly noticeable at shallow depths, and when bursting operations are conducted in sand." @default.
