摘要:: 根据基于应变与基于可靠性的两种管道设计新方法的工程需要，对我国油气管道面临的断层、采空、冻土、滑坡等常见地质灾害类型及其土壤位移模式进行了分类总结。以断层作用下管道设计应变计算的有限元分析力学模型及设计应变经验公式为基础，将其推广到采空、冻土、滑坡等其他地质灾害类型的研究中，提出简化的管道地质灾害综合位移模型及管道设计应变计算模型，模型将地质灾害位移类比为水平面和垂直面内的断层位移形式，从而衍生出其他地质灾害形式管道应变计算方法。该方法计算精度高、效率高、适用性广，特别是满足了多种地质灾害作用下油气管道可靠性的设计需要。

Abstract:: To meet the engineering requirements of two new pipeline design methods (i.e., the strain-based design method and the reliability-based design method), the common geological hazards (e.g. faults, mining subsidence, frozen soil and landslide) encountered by oil and gas pipelines were summarized and their soil displacement forms were classified. Then, a simplified geological hazard displacement model and a pipeline design strain calculation model were proposed by generalizing the mechanics model based on finite element analysis and the empirical formula for calculating the design strain of pipelines under the effect of faults to the other geological hazards, e.g. mining subsidence, frozen soil and landslide. In this model, the displacement of the geological hazards is regarded as the analog of fault displacement in vertical or horizontal plane. And as a result, the calculation method for pipeline strain subject to other geological hazards was derived. With the advantages of high accuracy, high efficiency and wide applicability, the proposed method is especially applicable to the reliability-based design of oil and gas pipelines under the effect of various geological hazards.
