Abstract: Buried gas pipelines in karst area are inevitably affected by the geotechnical activities, which is difficult to resist the permanent ground displacement caused by soil dislocation and surface damage. In this paper, abaqus ...

Abstract: Long-distance buried pipelines inescapably go through seismic fracture zones which makes the buried pipelines be easily influenced by the diastrophism. A strong and resilient pipe can withstand a certain degree of seismic ...

Abstract: In this paper, the hazard criteria for thermal radiation and shock wave overpressure applicable to the deflagration of urban gas pipelines have been proposed. The phast software is used to analyze the hazard intensity and ...

Abstract: In this paper, a risk analysis method of gas pipeline in karst area based on the integrated model of the decision-making trial and evaluation laboratory–interpretive structural model (DEMATEL– ISM) method and the cross-impact ...
