摘要
为了保证管道的稳定和安全,管道穿越水域及通过高地下水位地段时常需要进行抗漂校核及设计。针对海外项目普遍进行管道抗漂计算的需要以及ASME B31.4和ASME B31.8两个规范的要求,结合阿布扎比国家石油公司相关项目的设计经验,从未回填状态下管道浮力校核、回填状态下管道浮力校核(土壤饱和水)、试压条件下管道沉降校核及采取的抗漂措施四个方面,对管道抗漂进行计算,并对四种管径的管道进行了实例分析。阿布扎比国家石油公司相关项目的详细抗漂计算步骤及实例分析,对于执行海外同类情况的项目具有一定借鉴意义。
In order to ensure the stability and safety of the pipeline,anti-floating checking and design are often necessary when the pipeline passes through the water area and the area with high groundwater level.In view of the general needs of overseas projects for pipeline anti-floating calculation and the requirements of ASME B31.4 and ASME B31.8,combined with the design experience of Abu Dhabi National Oil Company related projects,the anti-floating calculation of pipeline is described in detail from four aspects:pipeline floating check without backfill,pipeline floating check with soil backfill(submerged in water),pipeline sinking check at pressure test condition,and anti-floating measures to be taken.Then,case analysis of pipelines with four kinds of diameters is carried out.The detailed antifloating calculation steps and case analysis of Abu Dhabi National Petroleum Corporation's related projects have practical significance for similar overseas projects.
