The Safety Assessment Method of Gas Pipeline Backfill Construction Based on Mathematical Model
The backfill process in gas pipeline construction is a key link,which not only needs to ensure the engineering quality,but also needs to ensure the construction safety.Therefore,a comprehensive assessment of the safety of backfill construction is of great significance for reducing the risk of accidents.Firstly,the backfill construction technology of gas pipeline is analyzed in detail,and the current situation and influencing factors of backfill construction technology are considered.Then,the mathematical model of backfill construction of gas pipeline is established,which considers the pipeline structure,backfill material characteristics,boundary conditions and load application mode,and the simulation is used to analyze the pipeline medium.Finally,the gas pipeline backfill construction technology and pipeline route are designed,and the effectiveness of the mathematical model is verified by numerical simulation under different conditions.The results show that the mathematical model can effectively predict and assess the safety of gas pipeline backfill construction.
