| 英文简介 | According to the flood characteristics,silt characteristics, geological features, flood characteristics and evolution law of the sandy desert river in xinjiang tarim river basin, based on the previous research results, to research on the structure type, and the scouring and silting characteristics of the permeable hydraulic flashboard spur dike. The main research methods including theoretical analysis, movable bed model test, and turbulent flow numerical simulation of computation fluid dynamics, etc. Specific study content as follows: the structure type and protection effects, hydraulic characteristics, the mechanism of scouring and silting, the key hydraulic problems in design of the permeable hydraulic flashboard spur dike. Aims to put forward optimal structure type and layout scheme of the permeable hydraulic flashboard spur dike, in order to obtaine scouring and silting laws in the action area of the spur dike, to quest the riverbank protecting and sediment promoting mechanism of the permeable hydraulic flashboard spur dike, to put forward the determination method about the key hydraulic parameters such as local scouring depth, height of backwater, water level descent, and backflow length,etc. The study works is of significance to exploring porous hydraulics scouring and silting characteristics of the permeable regulation structure. It provides theoretical basis for application of the permeable flashboard spur dike in river regulation and flood management in the sandy plain river in xinjiang tarim river basin. It will explore a new way for constructing more safe ,more economic，and more effective porous hydrophilic regulationg structure and permanent bank revetment project. |
