输油气管道建设中的水土保持研究

长距离的输油气管道建设引发的地质灾害和水土流失类型多样,空间分布差异大;会造成滑坡、泥石流、崩塌等地质灾害,也会引起土壤结构破坏和水土流失,影响区域的可持续发展。以西南地区的贵阳—重庆成品油管道工程为例,对建设过程中造成的地质灾害和水土流失进行了汇总、分析和研究,得到了其破坏机制和特点;并提出了相应的防治建议必须坚持“预防为主、防治结合、因地制宜、因害设防、综合治理”的方针和生态与经济建设同步发展的原则。研究成果对输油气管道工程的水土保持研究具有重要的工程和科学意义。

Research on Soil and Water Conservation in the Construction of Oil and Gas Pipeline

In the construction of long-distance oil and gas pipeline, geological disasters and soil erosion occur with different kinds and styles of spatial distribution. On the one hand, the construction will trigger geological disasters such as landslide, debris flow and collapse. On the other hand, it will lead to soil structural damage in association with soil and water loss. Guiyang-Chongqing pipeline project of oil products was taken as an example, which is in the southwest of China. Geological disasters and soil erosion caused by construction were summarized and analyzed for the project. On the basis of this, we obtained the behavior and characteristics of disasters and propose prevention measures. In other words, we must obey principles (prevention first, combining prevention with control, adjusting measures to local conditions, prevention for disaster and comprehensive management), for the purpose of developments of ecology and economy. Finally, the research results can be referenced for soil and water conservation in oil and gas pipeline projects.
