摘要
地质滑坡对油气管道的安全运行危害很大。建立横向滑坡管道有限元模型,分析管道的力学行为和极限状态,研究了滑坡位移、滑坡规模、埋深和土质等因素对管道变形和应力的影响,为可能滑坡地区管道的设计、施工和维护提供理论依据和技术参考。
Landslide is a typically poor geological conditions in pipeline engineoring, which Ires potential threats to pipelines. A finite dement model of pipeline subjected to transverse landslide is built. Effects of slip distance, landslide ex- tend, buried depth and soil character on pipeline deformation and stress are analyzed. So it can provide effective methods and references for design, construction and maintenance of pipelines in poor geological conditions of landslide.
