Abstract: This paper revievs the various types of excavation that are commonly situated near gas distribution pipelines. The principal soiu-ces of large ground movement are evaluated so that gas utility engineers can correct or minimize the consequences of large displacements and prevent related difficulties. Patterns of ground movement caused by excavations are summarized on the basis of field measurements. Ground movement effects on pipelines both parallel and perpendicular to excavations are described, and areas of potentially large pipeline deformation are identified. Recommendations are proposed for evaluating ground movement effects on buried mains and developing protective measures to insure safe pipeline operation.
