群桩作用下隔水导管可打性试验
DRIVABLE TEST OF RISER PIPE UNDER THE INTERACTION OF CLUSTER PILES
-
摘要: 结合海洋钻井实际工程情况,开展了群桩模拟试验,研究分析了群桩条件下的桩土相互作用问题,得出了群桩作用对土应力场的影响关系,模拟试验结果对海上隔水导管的施工具有重要的指导意义。Abstract: Simulation test of cluster piles was conducted in accordance with the engineering situation of offshore drilling.The interaction of seabed earth in cluster piling condition was investigated, and the influencing tendency of cluster piling on the stress field of seabed earth was also revealed.The simulation test results were very important for directing the operation of offshore riser pipe.
