Examples
- Studies on the characteristic of unsteady flow at lower lock approach deserve regards from the aspect of theoretical research and actual practice consideration
船闸下游引航道非恒定流特性的研究是一个在理论和生产实践中均值得重视的问题。 - In the whole course of flood regulation of tgp during flood season as well as filling and discharging of its shiplock , unsteady flow at different levels will occur in the upper and the lower access channels , which will exert an adverse impact on the navigation
摘要三峡水利枢纽在汛期调洪和船闸充、泄水运行全过程，在上、下游引航道内将产生不同程度的非恒定流，对航运构成相应的不利影响。 - Based on discussing methods to study the characteristic of unsteady flow at lower lock approach , several improved project proposals are provided , and then the alternate proposals are tested using both physical model and numerical model
在讨论船闸下游引航道非恒定流特性研究方法的基础上，对江苏泗阳船闸下游引航道非恒定流进行了分析研究，提出了几种工程改进方案，并相应地进行了数值计算和物理模型试验。 - Qinjiatuo bridge for three gorges project is a super bridge over the approach of the sea - route on lower reaches of the temporary lock . the bridge is 303 . 10m in length . the bridge is the heaviest - loaded bridge in asia at present , whose design loads are automobile - 135 and trailer - 660
三峡工程覃家沱桥为横跨临时船闸下游引航道的一座特大桥，大桥全长303 . 10m ，设计荷载为汽? 135级，挂? 660级，为目前亚洲第一重载桥。 - The pattern of flow of lower lock approach is usually complicated due to the influences of the interaction of flow underpoured from different locks . generally , physical model is applied to study the current field for the case of irregular boundaries and complex flow pattern
由于受多线船闸下泄水流相互作用的影响，船闸下游引航道非恒定流流态十分复杂，对于此类有复杂流态的非恒定水流运动问题一般采用物理模型进行研究。
