Abstract: An analytical procedure is proposed to determine the three‐dimensional response of a multiple‐cylindrical‐cavity system deeply buried in a viscoelastic medium subjected to moving or seismic loading. The tunnels are treated ...

Abstract: Estimation of the pulling forces during installation is an important step in the successful design of a horizontal directional drilling project. Moreover, estimation of the postinstallation loads is important for the ...

Abstract: High-density polyethylene (HDPE) pipes are subjected to tensile stresses and strains in the axial direction during and after a pulled-in-place installation by horizontal directional drilling or pipe bursting. During these ...

Abstract: High-density polyethylene (HDPE) pipelines are commonly installed using horizontal directional drilling (HDD), a trenchless construction technique used to replace or expand underground pipelines which generates cyclic axial ...

Abstract: The successful rehabilitation of three corrugated steel plate culverts consisting of 11.28-m-span horizontal ellipses is described. When constructed in 1970, the culverts were the longest-span horizontal ellipse culverts ...

Abstract: A scheme for reviewing the condition of long-span corrugated metal culverts is outlined. The scheme assesses the significance of observed pipe deformations. The scheme has been used successfully in Elgin County, Ontario, ...

Abstract: Pipe bursting is a construction technique that involves the replacement of an existing buried pipe with potentially much less surface disturbance than traditional cut and cover construction. However, excessive ground ...

Abstract: Deep-corrugated steel culverts (corrugation wavelength of 400 mm and amplitude of 150 mm) can be effective alternatives to short-span bridges. Because the corrugation dimensions are of a similar size to their minimum burial ...
