| Abstract: | Zichang section of West-East gas transfer pipeline in Shanxi Province of China is one of the fearful sections of frequent landslide disaster traversing the loess region.The creep of loess landslide located at DD277 of this section occurred in September 2007,which endangered the security of West-East gas transfer pipeline.On the basis of the landslide situation,the pacing factors affecting the stability of this landslide are analysed.As a matter of experience,the effective engineering methods to control the loess landslide on West-East gas transfer pipeline are given.It is of great practical significance to control the landslide in the oil and gas transfer pipeline engineering. |
