塔输轮南-鄯善输油(气)管道工程地质灾害发育特征及危险性评估

The Geological Disasters Development Characteristics and Risk Assessment of Lunnan to Shanshan Oil(gas)Pipeline Engineering

以塔输轮南—鄯善输油(气)管道工程为例,分析塔输轮南—鄯善输油(气)管道工程沿线地质灾害形成地质环境背景,提出沿线地质灾害发育特征,并对地质灾害危险性开展评估。研究表明,塔输轮南—鄯善输油(气)管道工程沿线地质灾害类型包括崩塌、泥石流灾害。地质灾害危险性评估面积1588.45 m^(2),其中,危险性中等区49.87 m^(2),占评估区面积的3.14%;危险性小区1538.58 m^(2),占评估区面积的96.86%。在此基础上,提出防治措施建议,为塔输轮南—鄯善输油(气)管道工程地质灾害的防治提供科学理论基础。

Geological disasters have a signifcant impact on the normal operation and management of oil(gas)pipeline projects,and many types of geological hazards are involved.This paper takes Lunan to Shanshan oil(gas)pipeline engineering as an example,analyze the geological environment background of geological hazards along the pipeline,put forward the development characteristics of geological disasters,assesss the risk of geological disasters.The research shows,the geological hazards type include collapse and debris flow along Lunnan to Shanshan Oil(Gas)Pipeline Projct,the geological disasters risk assessment total area is 1588.45 square kilometers,Include medium risk area 49.87 square kilometers,3.14% of the assessed area;low risk area 1538.58 square kilometers,96.86%of the assessed area.On this basis,prevention and control measures are proposed,put forward preventive measures proposal,it provide scientific theoretical basis for Geological hazard prevention of Oil(gas)pipeline project.
