摘　　要：作为城市生命线重要组成部分的城市主干给水管的安全影响着城市的正常运行,在工程建设中需要对其加以严格保护。新建电力管工程位于既有DN1800 mm城市主干给水管下方,并与其呈81°空间交汇,上下净距11.80 m。新建电力管采用水平定向钻法穿越,为确保既有给水管安全,采用有限元分析了穿越施工对管线的影响,在施工全过程对管道及管侧土体进行了监测,实测数据与有限元分析结果较为吻合,表明该施工方法是安全可行的。As an important part of the urban lifeline,the safety of the urban main water supply pipe affects the normal op-eration of the city,which needs to be strictly protected in the engineering construction.The new power pipe project is lo-cated under the existing DN1800 mm urban main water supply pipe and intersects with it in 81°space,with a clear dis-tance of 11.80 m from top to bottom.The horizontal directional drilling method is used to cross the newly-built power pipe.In order to ensure the safety of the existing water supply pipe,the finite element method is used to analyze the im-pact of the crossing construction on the pipeline.The pipeline and the soil around the pipe are monitored during the whole construction process.The measured data are in good agreement with the finite element analysis results,indicating that the construction method is safe and feasible.
