Direct Stress Monitoring of Pipelines and Development of Limitations - A Case Study 

A segment of high-pressure steel petroleum pipeline needed to be replaced on a hillside and beneath a waterway within an existing right-of-way containing multiple petroleum pipelines. The pipeline replacement required excavation of sedimentary rock to allow placement of the new pipe. As a result of an existing right-of-way limitation, steep slopes, and hard rock, blasting would be required as close as 7.8 meters (25 feet) from two operating pipelines.

Determination of Blast Vibration Limits by Direct Strain Measurement

Structural blast vibration limits should be based on the strength of the structure, the stress induced by blasting, and a responsible factor of safety. In this article a methodology that uses direct strain measurements to determine the stress induced by blasting is described.
