The major objective of Phase I of the program is: Develop an analysis procedure for determining the response of buried gas transmission pipelines to nearby (1 to 100 ft) blasting. This analysis considers all types of soil conditions commonly…
This report contains all the data traces recorded by Southwest Research Institute (SwRI) for the blasting research projects funded by the Pipeline Research Committee (PRCI) of the Pipeline Research Council International. In these two projects,…
This report contains handout material for the Seminar on Blasting Effects on Pipelines presented by the Pipeline Research Committee at San Antonio, Texas, October 26-28, 1981. Topics covered include: experiments and ground motion equations, pipe…
This item consists of two nomographs plotting pipe thickness, modulus of elasticity, equivalent charge weight, standoff distance, and circumferential or longitudinal stress. The two graphs cover different ranges of equivalent charge density and…

Blasting near buried gas pipelines is a common occurrence, and the blast-induced stresses can be significant relative to normal operational stress limits on a pipeline. Use of explosives for trench blasting in construction of pipelines adjacent to…
Occasionally, buried explosives are used within proximity of producing oil & gas wells which increases the stresses in the casing near the explosion which may result in failure of the well. A procedure was needed for predicting the maximum stresses…
This report describes a blasting research program conducted to develop simple procedures for predicting the maximum stresses in steel pipelines induced by nearby, buried, explosive detonations. Empirical analyses and test data were used to derive…
Current methods to assess pipeline response to nearby sub-surface blasting are largely empirical or semiempirical and do not consider increasingly important factors such as non-pristine pipelines, blasting in soil with varying soil and terrain…
Occasionally buried explosives are used within proximity of "in-service" pipelines which increases the stresses in the localized section of pipeline near the explosion which may result in pipeline failures. A procedure was needed for predicting the…
