系统回顾近几十年来国内外有关非均匀沙隐暴作用的研究状况 ,阐述诸多研究成果的局限性及其存在的不足。在此基础上 ,作者采用最新的矢量力学分析方法 ,探讨任意面上处于隐蔽和暴露状态的泥沙颗粒的受力关系 ,建立了更具一般性的非均匀沙起动流速矢量公式。文中又对不同方位床面上的泥沙起动公式进行有益的讨论 ,并对暴露状态下的一维公式进行了验证。 In this paper, we reviewed systematically the research status of the non-uniform sand storms at home and abroad in recent decades, and described the limitations and deficiencies of many research results. On this basis, the authors used the latest vector mechanics analysis method to investigate the force relationship of sediment particles in a hidden and exposed state on an arbitrary surface, and established a more general vector formula of non-uniform sand starting velocity. In this paper, we discuss the sediment start-up formula on the bed in different directions and validate the one-dimensional formula under the exposure condition.
