Paper presented at the ISRM International Symposium, November 19–24, 2000
Paper Number: ISRM-IS-2000-570
... ABSTRACT: A test conducted on buried HDPE pipe has been examined using finite element analysis to investigate a number of potential modeling choices. Issues considered include stress dependent response of granular materials, shear failure of the soil surrounding the flexible compressible pipe...

... in the ground adjacent to the westbound lanes. It was determined that erosion and piping of significant quantities of granular backfill soils into the deep storm drain system had occurred, primarily at unsealed pipe joints. This had resulted in collapsible voids above and around the storm drains, low-density...

... was abandoned at several years ago to follow legal restrictions. The investigation pursued two goals. One was to confirm whether or not the ground underneath pipe fittings of the storage tanks had been contaminated with TCE. A second goal consisted of carrying out a general investigation for the whole factory...

Unexpected catastrophic ground collapse above ageing infrastructure due to sewer or pipe collapse does occur. Excessive expenditure on new construction...

... ABSTRACT: Recently, small-diameter shallow tunnels are often being built by using slurry pipe-jacking. This is the sewage tunnel drivage method. This system involves the pushing or thrusting of a drivage machine through concrete pipes ahead of jacks. The mortar injection into the over-cutting...

... ABSTRACT: The restraints from the side fill on a buried pipe influence its deformed shape. It is often very difficult to compact well the side fill in narrow trenches. The trench width to pipe diameter ratio must necessarily be an important parameter in the design of buried flexible pipes...
