多年冻土区石油污染物迁移过程研究回顾与展望

Migration of the Petroleum Pollutants in Permafrost Regions:Review and Prospect

多年冻土区泄漏石油污染物会引起严重的环境和工程问题.通过对国内外石油污染物迁移过程、迁移机理、迁移模型、影响因素等研究进行回顾,基于国内外冻土区石油污染的研究进展和社会经济发展要求,提出了多年冻土区石油污染物可能引起的环境与工程问题,并对相关的科学问题进行展望,期望对以后研究工作有所指导并逐渐得到解决.

The spilled crude oil could result in serious environmental and engineering problems in permafrost regions. The related reviews on migrating process, mechanisms and mathematic models, and influencing factors, which were presented by domestic and foreign researchers, have been made. Based on the research advance, and social and economic requirements in cold regions, in this paper, some potential environmental and engineering problems were put forward and some related scientific vistas were opened for future research and expected to be progressively solved in coming decades. They include how the petroleum pollutants migrate in permafrost regions, how the permafrost influences the migration, what are the factors influencing the migration, what are the key driving forces, how the petroleum pollutants impact on the physical and mechanical properties of the pipeline foundation soils, what are the migrating models for the multi-phase flow in frozen soils.
