） Abstract： The risk is the harm to human beings in a certain period, caused by an outbreak of an activity or a event which people engage in
It depends not only on the frequency of the event, but also the size of event consequence
Pipeline risk can be described from different aspects, such as life risk, maximum individual risk, average personal risk of exposed population, average personal risk of total population and average mortality rate
The most common life risk indicators for oil and gas pipeline failure consequence evaluation include individual risk (IR) and social risk (SR)
This paper describes a simple method for long-distance gas pipeline life risk assessment
There are two important parameters, which are fatal length and cumulative fatal length
Thus a long-distance gas pipeline life risk assessment model is established
The quantitative calculation of pipeline risk is a prerequisite of risk acceptability assessment and risk decision-making
This paper will take individual risk and social risk as research object, which are indicators discribing the casualties in the vicinity of pipeline caused by gas pipeline failure, and explore life risk quantification
Thereby it is a basis for subsequent risk mitigation and risk decision-making researches
