【Abstract】 The first and the 2A bidding sections of West Section of Second West to East Gas Pipeline Project pass through two seismic fault zones, i.e. Keshi River seismic fault zone and Boa seismic fault zone. The technical summary on the pipeline construction in these two seismic fault zones is presented in aspects of pipe material, anticorrosion and girth welding performance as well as pipeline aseismic measures, aseismic construction and engineering aseismic check before acceptance, which will provide useful experience for similar projects.更多还原
