发布时间：2018-11-21 06:46
【摘要】：矮堰基础附近冲刷坑的深度是矮堰设计的重要参数,关系到建筑物的稳定与安全。系统回顾了国内外80余年关于矮堰基础冲刷的研究进展,阐述了矮堰基础冲刷的分类和机理,从物理模型试验、理论分析和数值模拟3个方面评述了研究现状和存在的不足。目前矮堰基础冲刷较为成熟的成果多集中于二维矮堰非淹没式清水冲刷方面,以物理模型试验方法为主,对于三维矮堰结构的动床冲刷、非冲积原状土床沙成分组成的影响、行进沙波与冲刷过程的耦合关系、浑水冲刷过程数值模拟技术等问题研究还有待深入。
[Abstract]:The depth of scour pit near the foundation of low Weir is an important parameter in the design of low Weir, which is related to the stability and safety of buildings. This paper systematically reviews the research progress on scour erosion of low Weir foundation in more than 80 years at home and abroad, expounds the classification and mechanism of scour erosion of low Weir foundation, and comments on the present research situation and shortcomings from three aspects of physical model test, theoretical analysis and numerical simulation. At present, the more mature results of erosion of low Weir foundation are mainly focused on the non-submerged clear water scour of two-dimensional low Weir. The physical model test method is the main method, and the effect on the moving bed scour and the composition of non-alluvial unscoured soil bed of three-dimensional low Weir structure is discussed. The coupling relationship between traveling sand wave and scour process and numerical simulation technology of muddy water scour process need to be further studied.
