摘要
本文应用空气动力学中机翼理论分析高速滑坡体在空气中滑行的规律,得出考虑到空气动力效应的运动微分方程,修正了滑坡体的抛体运动方程,为分析实际问题和估计灾害程度等提出了较为准确的定量分析方法,指出了其深入研究和应用的前景。
This study analyses the sliding law of the high-speed landslide body in the air in terms of plane wing theory and obtains a kinematic-differential equation in consideration of the airo-kinematic effect.Accordingly, the projectile-kinematic equation of the landslide boty is revised.This paper further presents a relatively accurate and quantitative method for both analysis of practical problems and for evaluation of damage degree.Finally the prospect of this study and its application are demonstrated.
