【摘要】 众所周知,给水排水管道是城市的生命线工程。在我国,给排水管道频繁爆裂带来了严重危害,因而有必要研究其原因及对策。本文对城市爆管现象的统计数据进行了比较,并探讨了管道爆裂的原因及机理。导致管道爆裂的主要原因有:①管道材料;②管道接口;③管道敷设深度:④管道的不均匀下沉。本文同时基于实际工程,提出了预防管线爆管的一些对策。更多还原

【Abstract】 It is well-known that water supplying and draining pipelines are cities’lifeline.Frequent pipelines bursting causes severe disaster in our country,so it is necessary to study its reasons and prevention measures.This paper makes detail comparison among statistical data of pipelines bursting and discusses its reasons and mechanism.The main reasons of pipelines bursting are as following:①pipelines ma- terial;②pipelines joints;③pipelines laying depth;④pipelines uneven subsidence. Some pipelines bursting prevention measures are also proposed in the paper based on actual engineering.更多还原
