摘要
长江口深水航道治理三期工程疏浚工程建设过程中，组织6艘装备ADCP的水文测验船，在国内首次采用多固定断面法对耙吸作业过程的溢流疏浚土及北槽内贮泥坑、抛泥区涨落潮抛泥过程中的疏浚土扩散情况进行了观测。首次在长江口成功获取了水体中疏浚土扩散场的实测资料，深化了对长江口疏浚土扩散特性的认识，在此基础上，改进了疏浚溢流和疏浚土处理的时间控制措施。
During the construction of the third stage of Improvement Project of Deep-water Channel of the Yangtze estuary, 6 ADCP hydrologic survey vessels were arranged to measure the diffusion condition of the suspended sediment via fixed synchronous cross section measurements, which was carried out in China for the first time. The result of suspended sediment diffusion field was observed when the dredged sediment was overflowed during dredging in channel and deposited in the disposal area in the north passage of the Yangtze Estuary during the tidal fluctuation period. According to that, the optimized construction method was improved.
