摘要: Long-distance natural gas transmission pipelines are designed to cross the large-scale mountain area with start of West-East Gas Pipeline Project in China. A great portion now threatened by severe landslide hazards. The pipeline could fail resulting a loss because failure deformation. Therefore, spatial arrangement plan underground crossing is one key problems. paper presents new mechanical model and under trapezoidal force conduct analysis on deformation pipeline. series shear force, bending moment defection different angle can be deduced according simplified presented. Based case study typical crossing, geological system established. characteristics conducted driving utilizing mechanics theory so as determine position maximum stress point along Consequently, optimal depth orientation obtained. result shows that proper setting buried effectively improve safety pipelines. corresponding control strategy suggestions for similar projects proposed well.
