| 摘 要： | 针对杭州湾海底管道的实际工程状况,使用声学探测技术对海底管道冲刷自埋演化过程进行了现场检测,验证了海底管道从初始敷设状态依次发展为孔道冲刷、部分掩埋、尾流冲刷、尾流冲刷平衡、再次孔道冲刷和回淤自埋状态的演化过程.采用数值模拟方法分析了海底管道自埋演化过程中的典型状态,结果表明:管道下方的渗流和天然微孔隙是孔道冲刷起动的...

| Abstract: | An acoustic detection technique was used to inspect the process of scouring and self-burying of the submarine pipeline in Hangzhouwan Bay.It is verified that the self-burial process includes pipeline-touch-down,tunnel erosion,partial burial,wake scouring,wake erosion equilibrium,second tunnel erosion and backfilling till self-buried state.The typical states in the process were analyzed with numerical modeling method.The results show that the seepage flow and piping underneath the pipe is one of the driving ... |
