| 摘 要： | 天津港15万吨级深水航道二期工程将航道高程从-14.8m浚深至-17.4m,在航道底部遇到约2.6~3.0m的粉沙层。针对粉沙运动的特性,采用试挖槽观测、模型试验、示踪沙试验等方法进行了研究,并对航道开挖后的泥沙回淤进行了预测。

| Abstract: | During implementation of Tianjin Port 150 000 DWT Deepwater Channel Phase II Project, which was purposed to excavate the channel from the elevation of -14.8m to -17.4m, silt layer of 2.6~3.0m deep was found in channel bottom. In the light of the characteristics of silt motion, methods such as observation through trial tunnel, model experiment, and sand tracing test, etc. were studied and back silting in the channel after excavation was forecasted. |
