考虑事故工况的城市燃气管网规划方案比较

Comparison on urban gas pipeline planning scheme with accident condition taking into consideration

以某市新区的燃气管网规划为例,在管网水力计算完成的基础上,确定了几个特定的事故工况,并对这些事故工况进行了分析计算,清楚地比较出不同方案的水力稳定性,为燃气管网规划的方案比较提出了新的思路和方法。

Taking the gas pipeline planning of the new city region as an example,based on accomplishing hydraulic pipeline calculation,the paper determines several certain accident conditions,and analyzes and calculates the accident conditions,and clearly compares the hydraulic stability of different schemes,which has provided new concept and method for the comparison of gas pipeline planning scheme.
