| 摘 要： | 群发性崩塌具有速度大,破坏性的特点,一直以来都是按照自由落体进行研究,忽略空气的作用,这对群发性崩塌的预防和防治带来了误差.建立崩塌体垂直下落的模型,考虑空气对崩塌体的作用,通过理论推导,数值计算的方法,考虑空气外泄系数,应用空气动力学理论分析崩塌体在空气中的运动,从而得到在考虑空气效应后崩塌体到达沟谷的速度,以及封闭...

| Abstract: | The mass landslip takes rapidity and destructive characteristics.Without taking the function of air into accout,studied by free fall for a long time,it could lead to errors for the prevention and control of the landslip.The model of vertical drop collapse body was established;a more accurate quantitative analysis method for analyzing the practical issue and estimating disasters was obtained,which was proposed by considering the speed of collapse body reached gully after the air affect and closed air volume.By considering the role of air to collapse body,the air out releasing coefficient was calculated through the theory derivation and numerical calculation method. |
