研究了围堰工程对地下管道的服役性能影响。首先介绍了管线类型判别、荷载特性以及服役性能分析方法。进一步地介绍了某地下排污管道的工程背景。基于数值分析方法考察了该管线的服役性能,为结构体系的长期使用和维护提供了相关依据。研究表明,该管线在上部围堰施工过程中其变形、强度和稳定性均满足要求,不会引起结构的损伤和破坏。
The effect of cofferdam engineering on service performance of underground pipelines was studied. First of all, it introduces the pipeline type identification, load characteristics and service performance analysis methods. Further introduces the engineering background of an underground sewer. Based on the numerical analysis method, the service performance of the pipeline is investigated, which provides the basis for the long-term use and maintenance of the structural system. The research shows that the deformation, strength and stability of the pipeline meet the requirements during the construction of the upper cofferdam, and will not cause structural damage and damage.
