摘要
目前国内油气长输管道建设项目,通常采用建管分离模式,建设单位为了控制工程投资,将工作重点放在主体工程的建设上,对保证管道安全运行的地质灾害防治工作停留在轻"事前"重"事后"、轻"规划"重"补救"的层面,尤其是在地质灾害频发的地区,运营期管道的抢维修和隐患治理给运营单位带来了很大的成本和安全压力。通过阆中-南充输气管道的建设,运用地质灾害风险管理的方法,对该管道所经地区的地质、地貌特征以及灾害类型进行分析,对管道全生命周期的各个环节提出了具体做法,通过工程实践,建立了一套科学、经济的管道地质灾害防治体系,实现了管道长期安全稳定运行的目标。
At present,the long-distance oil and gas pipeline construction projects in China are carried out under the construction-management separation mode. In order to control the engineering investment,construction companies usually give the priority to the construction of main projects. However,the geological disasters prevention and control work in ensuring safe operation of pipelines still remain at the level featured by placing post-disaster recovery prior to pre-disaster planning. The risk management and emergency response to the operating pipeline problems that occurred particularly in the regions highly affected by geological disasters have brought tremendous repairing costs and safety pressures to the operation companies. Drawing on the risk management measures against geological disasters,this essay adopts a case study method based on the construction Langzhong-Nanchong（LN） gas pipelines. The essay examines the geological and geomorphological characteristics as well as the disaster types of the regions that the LN pipelines were built through,and proposes the specific solutions to the different stages of the full life cycle of the gas pipelines. Through engineering practice,a scientific and economical system of preventing and controlling geological disasters in pipeline construction of has been established,thus ensuring the long-term safe and stable operation of long-distance pipelines.
