- Abstract
The full-bore rupture of a buried high-pressure natural-gas pipeline can lead to detonation waves that can pose a significant threat to underground structure in the vicinity of failure location. The dominant hazards are shock wave propagation through the soil around the underground structure from buried pipeline physical explosion. In this paper, a methodology is presented to evaluate hazard areas of underground structure relating the diameter, the operating pressure, the length of pipeline, soil characteristics, the distance between buried pipeline and underground structure. An effective thermodynamic method is proposed to estimate the energy of buried pipeline physical explosion. TNT equivalent model is utilized to convert buried pipelines physical explosion energy, two simplified models are proposed, concentrated mass and linear distribution per unit length, to comprehensively describe the effective physical explosion range of the longitudinal length of the pipeline. The methodology can be readily used by practicing engineers to calculate the shock wave pressure of existing or constructing underground structure subjected to pipeline physical explosion.
