Effects of Cofferdam Engineering on the Performance of Underground Pipelines

The effects of cofferdam engineering on the performance of underground pipelines are actively investigated in this study.The judgment of pipeline category,properties of loading and service performance are firstly introduced.Then,the background of a real blowdown pipeline is illustrated.The performance of the blowdown pipeline is investigated through numerical simulation and the results are provided as the guidelines for long term service and maintenance.The made observations indicate that the deformation,strength and stability of the blowdown pipelines subjected to cofferdam loading are satisfied and no damage event can be induced.
