摘要
分析了供水管网产生爆管的原因,并对预测机制进行研究,确定管网中存在爆管隐患的管道。从各方面分析了管网产生爆管的原因,并以T市供水管网为例,通过建立爆管预测模型,分析计算管道组爆管率,进而计算联合爆管率,确定了存在隐患的管道。结果表明,管道P-9397的联合爆管率最大为63.166 9%,存在较大安全隐患,应锁定该管道在管网中的位置。爆管原因错综复杂,通过分析计算,确定可能产生爆管的管道,并进行修复,以提高供水管网的安全可靠性。
The pipe burst causes were analyzed in water supply network,the prediction mechanism was investigated,and the pipes with hidden danger were determined.The causes of pipe burst were analyzed from several aspects.Taking water supply network of T City as an example,the pipe burst possibility of pipe set was analyzed and calculated by a pipe burst prediction model established,then the burst possibility for combined pipes was calculated and the pipes of potential risk were determined.The maximum burst possibility for combined pipes was 63.1669% for the P-9397 with a high potential risk.The pipe locations could be confirmed.Due to the complicated cause of pipe burst,if the pipe with potential risk could be determined by analysis and calculation,the repairing would be carried out in order to improve the safety and reliability of water supply network.
