摘　　要：城市地下管道设施是城市功能正常运转的“生命线”,下埋管道高路基施工过程中,为保证城市管道设施的正常使用,需控制附加荷载与地面沉降。文章以东靖路新建工程上跨污水处理管道的道路施工为例,分析了常规施工和EPS(发泡聚苯乙烯)施工的附加荷载与沉降差异,并介绍了EPS路基在管道上方施工的具体方法。该案例作为EPS路基在下埋管道高路基施工中的成功实践,对类似工程施工具有借鉴意义。Urban underground pipeline facilities are the"lifeline"of the normal operation of urban functions.In order to ensure the normal use of urban pipeline facilities,it is necessary to control the additional load and land subsidence during the construction of high subgrade of buried pipeline.Taking the road construction of the new project of Dongjing Road crossing the sewage treatment pipeline as an example,this paper analyzes the difference of additional load and settlement between conventional construction and EPS(Expanded Polystyrene)construction,and introduces the specific method of EPS subgrade construction above the pipeline.As a successful practice of EPS subgrade in the construction of buried pipeline high subgrade,this case has reference significance for similar engineering construction.
