摘要: |
在分析传统堆石丁坝特点的基础上,提出了排桩式丁坝,并分析了其护塘功能、坝型选择、坝群布置、结构设计等关键问题.实际运行情况表明,排桩式丁坝能有效地减轻涌潮对近塘滩地的冲刷,大幅度减轻局部冲刷,提高丁坝的稳定性,在河口治理、护塘和促淤工程中具有广泛应用价值. |

Abstract: |
Based on analyses of the traditio protection function, groin form selection, lay Practical operation results show that the sheet and can improve the stability of groins. The seawall protection and siltation accretion. nal rockfill groins, the sheet-pile groin is out of groin group, and structure design of -pile groins can reduce beach scour near the sheet-pile groin has been widely applicated presented. The seawall the groin are analyzed. ponds and local scour, to estuarine regulation, |
Key words: sheet-pile groin rockfill groin beach protection and siltation accretion structural design estuary of Qiantang River |
