【摘要】 管道建设工程所面临的风险因素较多,在建设过程中重、特大事故偶有发生。为了更好地规避风险,减少建设过程中的损失,有必要对管道工程风险进行系统研究。以某大型管道工程为对象,在现场踏勘的基础上,从单一风险的可能性和严重性2个方面分析被评估单元所面临的风险,进而得出被评估单元的综合风险状况,最终得出地质断裂带(地震)风险、雪崩风险、隧道施工风险、第三方责任风险和试车期高压天然气风险是对工程危害最大的风险因素。应重点关注可预测类风险,做好风险易发区段的管理工作。更多还原

【Abstract】 Some major accidents have happened occasionally in the construction of long-distant natural gas pipeline,so it is necessary to study the risk of the pipeline system in order to better avoid the risks and lessen the losses of properties.Based on the survey datum,the comprehensive risk status of the evaluated unit is found out through analysis of the possibility and severity of every risk in unit.Conclusion is concluded that the higher risk factors includes earthquakes,avalanches,tunnel construction,the third party liability and high pressure natural gas.So it is necessary to consider the risk of predictability and do a good job of risk management.更多还原
