摘要： 针对草方格沙障防护区域内流场的特点,提出一个单排理想涡列模型,用以模拟实际风沙流场。在此基础上,利用流体力学的分析方法,给出了与目前工程实际所建议的尺寸比较吻合的草方格沙障间距(或草方格边长)与出露草头高度的对应关系。
关键词: 草方格, 流体力学, 理论模型
Abstract: Straw checkerboard barrier is a kind of very useful barriers to reduce wind-blown sand transportation. According to the characteristics of the actual flow field in straw checkerboard barriers, a theoretical model, that is one-row-vortex model, is suggested to simulate the flow field in the straw checkerboard barriers. The measurements for one straw checkerboard barrier, such as its length and its height out of the sand bed, which have very important influence on the effect of the sand-breaks, are calculated by the model and hydrodynamic theory.
Key words: straw checkerboard barriers, hydrodynamics, theory model
