Abstract: With rapid development of China national economy, the energy demand continues to increase in the central and southeast-coastal areas of China. China timely to start the west-east gas pipeline Ⅲ project to import the abundant natural gas in Central Asia.The west-east gas pipeline Ⅲ has a 5220km pipeline which obliquely across the western, central and south-east of the country. There is a variety of physiognomy in the areas along the gas pipeline and the seismogeological environment is so complex that prone to geological disasters.It is important for the feasibility studies of the project to have an intensive geological survey and study along the pipeline areas, including the study of active fault, the earthquake and geological disasters dangerous analysis, and local tectonic stability assessment, in order to ensure the pipeline safe in its lifecycle, neither in its design, construction nor operation.
