- 摘要:
- 为有效抑减液体管道穿越河流溢油环境风险，针对流宽较大（≥20 m）和流速较高（≥0.4 m/s）的河流穿越，以小孔泄漏为情景，分有压和无压进行管道泄漏量仿真，综合考虑重力、惯性力、表面张力等内力和水力、风力等外力作用，采用理论和经验模型相结合的方法进行溢油扩散过程模拟，依此厘定下游拦截位置；上述工作基础上，按照“高集油-低走水”原则，进行“围栏选型-角度&长度计算-拉力校核”等方案设计，提出1套基于“扩散-拦截-回收”分析框架的拦截处置方案，并以西北地区2处液体管道穿越为样板进行范例研究。研究结果表明：在应急资源抵达时间较长情形下，溢油扩散距离及其影响范围主要受水力和风力为主的外力影响，流速效用最显著；上述背景下，宜充分发挥闸坝体系水情调控功能，结合围油栏科学布放，进行水面油品聚拢和回收，有效提升现场处置效率。研究结果可为液体管道穿越河流潜在泄漏应急响应和科学处置提供技术范式。
- Abstract:
- In order to mitigate environmental risks posed by oil spill diffusion from liquid pipeline-river crossings,specifically for wide river (≥ 20 m) with higher flow velocity (≥ 0.4 m/s) crossings,the small-aperture leakage was validated under both pressurized and unpressurized conditions.Comprehensively incorporating internal forces such as gravity,inertial force,and surface tension,along with external forces like hydraulic and wind forces,the distance of oil spill diffusion was simulated based on the combination of theoretical and empirical models to determine the downstream interception positions.Building upon the above and guided by the principle of “higher oil collection-lower water flowing”,a scheme design was developed containing “boom selection-angle & length calculation-tension verification”,leading to a novel “Diffusion-Interception-Recovery (DIR)” based analysis framework for emergency treatment.Case studies of two liquid pipeline-river crossings in Northwestern China were conducted.Results indicate that,under conditions of delayed emergency resource arrival,oil spill diffusion and its impact range are primarily governed by external forces,with the flow velocity influencing mostly.In such scenarios,leveraging existing dam and weir systems to regulate flow and water levels is recommended.Combined with reasonable oil boom deployment,oil recovery and on-site response efficiency could be effectively enhanced.The study might offer a technical paradigm for emergency response and scientific management of potential oil spills from liquid pipeline-river crossings.
