摘要:
针对影响长输埋地管道安全运行的山体滑坡问题，基于深层圆弧形滑坡理论和有限元方法，建立了在深层圆弧形滑坡作用下的管道计算 模型，对管道的受力进行了数值模拟。对土壤密度、管道壁厚、管道内压以及土抗剪强度进行了参数敏感性分析，研究了各参数对发生滑坡时 管道所受最大应力的影响规律。结果表明：当滑坡规模、滑坡角度增大时，管道所受Von Mises值会随之增大；随土壤密度的增加，管道所受的 应力也会增加；在滑坡多发区，应设计大壁厚的管道，以增加管道安全性；应确保管道内压小于10MPa，当内压突增时应有紧急预案；土抗剪强 度对在深层圆弧形滑坡作用下管道所受应力的影响明显小于其他3个敏感参数。该研究工作为山体滑坡区的安全管道设计提供了一定的参考，对 确保滑坡区埋地管道的安全运营有重要意义。
Abstract:
Aiming at the problem of landslide which affects the safe operation of long distance buried pipelines, based on the theory of deep circular arc landslide and finite element method, a calculation model of pipeline impacted by deep circular arc landslide was established, and the stress of pipeline was numerically simulated. The parameter sensibility analysis was conducted on soil density, wall thickness, pipeline internal pressure and soil shear strength, and the influence of each parameter on the maximum stress of pipeline in the landslide was researched. The results showed that when the landslide scale and angle increase, the Von Mises value of pipeline will increase. The stress of pipeline will increase as the soil density increase. In the prone areas of landslide, large wall thickness should be designed to increase the pipeline safety. The pipeline internal pressure should be less than 10MPa, and when the internal pressure increases, there should be an emergency plan. The impact of soil shear strength on the stress of pipelines under deep circular arc landslide is less than other three sensitive parameters obviously. The research can provide a reference for the safe design of pipeline in the landslide areas, ant it has an important significance to guarantee the safe operation of buried pipelines in the landslide areas.
