Southwest Research Institute presents the experimental test results and findings of a program aimed at developing procedures for predicting the maximum circumferential and longitudinal stresses in pipelines caused by nearby buried explosive detonations. SwRI studied the problem in two parts, estimating (1) maximum soil-particle velocities and displacements at various distances from single (point-source) and multiple (line-source) explosions and (2) the resultant stresses in buried pipe caused by these maximum ground motions. It found that pipe stresses are most sensitive to the standoff distance and least sensitive to the modulus of elasticity of the pipe and pipe thickness. Surprisingly, pipe stresses are independent of the soil density, the soil seismic propagation velocity, and the pipe diameter. To help guide corporate development of a field manual based on these research findings, SwRI discusses various uses of predictive equations and illustrates applications for computing pipe stresses from blasting.
