Dynamic response of buried oil pipeline to blasting construction of the second submarine tunnel in Jiaozhou Bay
To further study the dynamic response mechanism of buried oil pipelines and the vibration velocity law of oil pipelines under different working conditions,this study took the Huangdao end inclined shaft phase Ⅱ project of the second submarine tunnel of Qingdao Jiaozhou Bay as the background and the buried oil pipeline in the Qingdao Oil Port dock plant as the research object.Based on the measured data,a numerical model was established by using ANSYS/LS-DYNA software.The oil pipeline's vibration velocity prediction model was established by simulating the three working conditions of detonation charge,detonation center distance,and pipeline buried depth.The results show that the vibration velocity on the pipe ring's side is greater than that on the back explosion side of the pipe ring,and the maximum value of the axial peak vibration velocity of the pipeline appears on the pipeline cross-section about 4 m in front of the working face.The obtained vibration velocity prediction model of buried oil pipelines can provide important reference for the protection of the neighboring buried oil pipelines in engineering blasting construction.
