| 摘 要： | 通过比尺为1∶20的船厢出入水物理模型,系统研究船池面积和船厢出水速度对下水式升船机船厢出水水动力特性的影响。结果表明:船池与船厢间隙面积与船厢面积比β的增大可有效降低船厢出水启动力、引航道内水面最大坡降,改善船池内船厢停泊条件;结合船厢入水过程水动力特性以及工程实际,建议船池与船厢间隙面积与船厢面积的最佳比值β为1.24。

| Abstract: | A research,which aims at the TSHD issues of complicated working conditions,big hopper,great dredging depth,accurate and highly efficient controllability and fine sailing performance,is conducted in the aspect of hull shape,serialized drag-head,high-efficiency dredging pump,pump for drag-head boom,as well as the control system.Several methods are adopted such as theoretical research,large-scale model experiments,test on dredgers,etc.,which solve the bottleneck problems that limit the technical domestication of the jumbo TSHD.Based on the above-mentioned achievement,2 jumbo TSHDs are designed and built,and applied to several key projects of port and waterway,which achieved remarkable social and economic benefit. |
