摘要/Abstract

摘要： 在溜砂坡系列研究之二的基础上，对风干砂的运动特征进行了细致观察。将干砂流视为连续介质的流动，对干砂流的运动动力和阻力进行了深入研究，建立了干砂流垂线流速分布方程和干砂流体底面、表面滑动速度方程。结合挡砂工程，将干砂流体视为沿底面（此种砂坡的天然休止角）滑动的三角体，从而导出粒状碎屑溜砂坡水平土压力（或水平推力）计算模型。

关键词: 干砂流, 底面滑动速度方程, 表面滑动速度方程, 砂坡土压力

Abstract: The motion and soil pressure of air dried sands are studied based on field observations and investigations. First, the driving and resisting forces for movement of dry sands, which is regarded as a continuous medium that can flow, are analysed thoroughly. Then the equations for velocity distribution along vertical direction of the dry sand flow and that for velocity of sand mass sliding along the subface and top surface are derived. Finally, a calculation model for the horizontal earth pressure of granular flowing class or sands on the retaining wall is derived in connection with practical retaining works, in which the dry sands are treated as a triangular body.

Key words: dry sand flow, velocity equation for sliding along subface, velocity equation for sliding along top surface, soil pressure of sand slope
