深圳市某河道截污管道近距离上穿既有大直径地下供水管道有限元分析

城市建设过程中各类地下管线交叉不可避免,由于地下管线材质、管径、使用功能、荷载不同,常规计算方法繁琐且不够直观。为此,通过有限元方法分析了深圳市某河道截污管道近距离上穿既有大直径地下供水管道问题,为既有管道安全和正常使用提供了直观的计算结果,亦为工程设计和施工方案提供了技术支撑。

Finite Element Analysis of a Sewage Interception Pipeline in a River Improvement Project in Shenzhen through an Existing Large-diameter Underground Water Supply Pipeline at a Close Distance

In the process of urban construction,the intersection of various underground pipelines is inevitable.Due to the different materials,pipe diameters,use functions,and loads of underground pipelines,conventional calculation meth-ods are cumbersome and not enough intuitive.Therefore,the finite element method is used to analyze the problem of a river sewage interception pipeline passing through an existing large-diameter underground water supply pipeline at a short distance,which provides more intuitive calculation results for the safety and normal use of the existing pipeline as well as technical support for engineering design and construction plan.
