Based on the safety distance from the oilfield facilities to the nearby structures and facilities specified in the national and industrial standards, the relevant technical requirements are proposed and SAFETI software is applied to quantitatively evaluate the safety influence on the oilfield production facilities, the safety distance from the productio.

Based on the analysis of the safety distance of traffic flow on expressway,the conception and calculation method about basic safety distance were proposed,which can ensure the safety of traffic flow.

According to the relationship between gas pipeline and cantilever pipes,the calculation model of safety distance that gas pipeline horizontally passes through foundation ditch of cantilever piles is established.
