Dynamic behavior and failure of buried gas pipeline considering the pipe connection form subjected to blasting seismic waves

To ensure the safety of gas pipelines during tunnel blasting excavation, it is of vital significance to investigate the dynamic response of buried gas pipelines under blasting vibration. Based on a great number of engineering examples, a representative buried gas pipeline with a diameter of 1 m and a wall thickness of 10 cm in the urban area was taken as the research object, and a full-scale buried gas pipeline blasting experiment on basis of...
