Course overview
The Pipeline Toolbox is home to many tools and calculators. The PLTB User’s Guide presents information, guidelines and procedures for use during construction, operations and integrity tasks for field or office applications.

The general problem of a buried explosive detonating near a pipeline consists of two parts. The-first part, similitude theory; empirical analyses and test data were used to derive equations for estimating maximum ground displacement and particle velocity. The ground motions., provided the forcing function imparted to a buried pipeline. The second part, similitude theory, conservation of mass and momentum, and approximate energy methods were used to derive functional relationships for the maximum pipe strains and stresses. Experimental data from more than 60 tests, primarily in model scale, were then used to develop equations for estimating maximum pipe stresses induced by point and parallel line explosive sources buried in a homogeneous soil ‘media. The large amount of data used, and the wide range of these data make the solutions applicable to most soil blasting situations near pipelines.
