  • Loess water erosion constitutes a great threat to the safety of the West-to-East Gas Pipeline in China. Through aerial-photo interpretation and investigation of the typical region (Zichang (子长)-Yongping (永坪) Section) where the loess water erosion problem is intensely developed, the influence of water erosion on the pipeline in the loess area can be manifested as the following 3 aspects: (1) surface and gully erosion causes the base overhead and pipeline exposure; (2) underground erosion forms caves, which may cause surface subsidence and foundation failure; (3) water erosion of loess may destroy the balance of slopes and cause geological hazards like landslide, collapse and debris flow. Presently, the controlling methods are mainly concrete or grouted rubble protection...

Abstract: Loess water erosion constitutes a great threat to the safety of the West-to-East Gas Pipeline in China. Through aerial-photo interpretation and investigation of the typical region (Zichang (子长)-Yongping (永坪) Section) where the loess water erosion problem is intensely developed, the influence of water erosion on the pipeline in the loess area can be manifested as the following 3 aspects: (1) surface and gully erosion causes the base overhead and pipeline exposure; (2) underground erosion forms caves, which may cause surface subsidence and foundation failure; (3) water erosion of loess may destroy the balance of slopes and cause geological hazards like landslide, collapse and debris flow. Presently, the controlling methods are mainly concrete or grouted rubble protection...
