Environmental geological problems and countermeasure of oil pipeline from Yan'an refinery to Xi'an

摘要

The project of oil pipeline from Yan'an refinery to Xi'an is a key project carried out by Yanchang Petroleum Group Company of Shaanxi province. By collecting the data of the meteorological, hydrological and geological conditions along the pipeline, the authors analyze the environmental geological problems that may occur in the project area. These problems include loess collapsibility, gully erosion, loess cave, unstable slope, active faults and ground fissures, and so on. The influence of these problems on the pipeline is also analyzed, and corresponding measures are put forward.
